Spark Plug Replacement & Misfire Repair
Brooklyn stop-and-go cooks spark plugs. When plugs wear out, your engine misfires, runs rough, burns extra gas, and can destroy the catalytic converter. We replace spark plugs the correct way (torque spec, correct gap, anti-seize only when required) and diagnose coils when the problem isn’t “just plugs.”
Local coverage: Serving Sunset Park, Bay Ridge, Park Slope and surrounding Brooklyn neighborhoods — ~5 miles radius from 11232.
✅ NGK / Denso / Bosch
✅ Iridium & Platinum
✅ Coil-on-Plug Diagnosis
✅ Misfire Testing
✅ MPG Restoration

Signs You Need Spark Plugs
Rough Idle
Shaking at red lights means one or more cylinders aren’t firing clean.
Poor MPG
Worn plugs force the engine to work harder and waste fuel.
Hesitation
Stumble when accelerating or merging onto the highway.
Check Engine Light
Misfire codes (P0300–P0306) often point to plugs/coils.
Hard Starts
Cranks longer before starting, especially in cold weather.
Loss of Power
Car feels “heavy” and weak climbing hills or loaded.
Spark Plugs vs Ignition Coils (Stop Guessing)
Worn Spark Plugs
Plugs wear gradually. Symptoms usually build over time: poor MPG, sluggish acceleration, rough idle.
- Common near 60k–100k miles (depends on plug type).
- Can trigger misfire codes.
- Cheaper fix when done on time.
Failing Ignition Coils
Coils fail suddenly. You can go from “fine” to “shaking violently” in one day.
- Often misfire under load or when hot.
- Common on coil-on-plug engines.
- We test before replacing parts.
Our Spark Plug Standard (Done Correctly)
Wrong plugs or wrong install = stripped threads, misfires, and repeat repairs.
| Step | Why It Matters | Our Standard |
|---|---|---|
| Code Scan | Confirms which cylinder is misfiring and why. | OBD scan + live data review. |
| Correct Plugs | Heat range and design must match the engine. | OEM-spec NGK / Denso / Bosch. |
| Torque Spec | Too tight strips threads; too loose causes blow-by. | Torqued to spec; no “impact gun” nonsense. |
| Gap Handling | Iridium tips can be damaged if gapped incorrectly. | We follow manufacturer guidance. |
| Coil Inspection | Boots crack and arc; coils fail and mimic bad plugs. | Boot check + swap test when needed. |
| Final Test Drive | Verifies misfire is gone and trims look normal. | Warm-up + verification scan. |
Verification: We confirm the engine runs smooth and the misfire counters stay at zero.
Common Spark Plug Issues by Brand
Honda / Acura
High-mileage plugs cause rough idle and misfire under load. V6 engines may require more labor due to access.
BMW / Mini
Coils fail often. We test coils before you waste money replacing parts blindly.
Toyota / Lexus
Long-life Iridium plugs still wear. When MPG drops and idle gets rough, it’s usually time.

Spark Plug FAQ
How much does spark plug replacement cost?
It depends on the engine and access. Some cars are fast; others require intake removal. Call with Year/Make/Model for a real quote.
Can I drive with a flashing check engine light?
No. A flashing light means active misfire. That raw fuel can destroy the catalytic converter. Shut it down and call.
Do I need coils with spark plugs?
Not always. If coils test weak or boots are cracked/arcing, then yes. We test first and only replace what’s proven bad.

I was looking for a new tire and same day service on an uncommon tire size. Ali was very helpful and recommended 2 spots where I would have some luck finding the tire and getting it replaced same day.

I don’t usually write reviews, but I know how important they are when it comes to auto repair. Like many people—especially women—I’ve experienced being taken advantage of at my dealership. After a routine service visit to the Nissan dealer turned into unnecessary services and thousands of dollars in repairs, I was left feeling completely ripped off and discouraged.
After that experience, I was hesitant to trust another shop until I found A&A Auto Repair which was recommended by my friend. From the moment I walked in, Ali was polite, honest, humble, and respectful. He thoroughly explained what needed to be fixed now and what could wait. I needed brakes, a motor blower replacement, an oil and filter change, and two new tires—and the price he quoted was less than a quarter of what the dealer charged me for far less work.
As a single parent, that honesty and fairness meant everything to me. For the first time, I didn’t feel like I was taken advantage of or or regretful that I did not bring a man w/ me. I felt his hospitality and genuinely respected. He followed up w/ me the very next day to see how the car was working and to reminded me of our next appointment to finish everything off. Ali has earned my trust and will absolutely be my mechanic moving forward 😉 Thank you, Ali. More then you know!!!
See you soon

I came in because my check engine light came on, and Ali took care of the issue immediately. He was professional, knowledgeable, and provided great service from start to finish. Everything was explained clearly, and my car was taken care of quickly. I really appreciate the excellent service and would definitely recommend this shop.

Great shop and super quick. I spent a month at other shops trying to figure out my steering issue with my hybrid and nobody could figure it out. They found the issue and solved it in 2 hours. So grateful.

I had an amazing experience at this shop. From the moment I walked in, the staff was friendly, professional, and transparent about everything my car needed. Ali and his assistants are quick and amazing. My car needed catalytic converters, Ali got me 2 for a good price, did some welding. My car is 2004 and runs like new! The prices are fair, work is quick, hospitality and customer service is outstanding. If you’re looking for a reliable and trustworthy place to get your car fixed, I highly recommend this shop. I won’t be taking my car anywhere else!

Ali and the shop did a wonderful job with my car. I came to him with a long list of issues that a dealership had flagged; he confirmed some, let me know others were not needed, and found an issue they missed. His price was so much lower than the dealership and he got everything done fast and with care. Would 100% recommend!

I had a really good experience here. The staff was friendly and straightforward, and they got the job done much faster than I expected. The quality of the repair was excellent, and the price felt fair compared to other places I’ve been to. It’s hard to find an auto shop you can trust, but this one definitely earned my confidence. Special thanks to Ali for the great service — I’ll definitely be coming back here for future work.

This place has been a godsend and feeling super lucky to have found Ali here where there are tons of auto shops but so rare to find somebody as honest and hard working as these guys. Took care of my sedan first and did such a quick and amazing job that I took my truck there about a month later with its own problems and they were taken care of perfectly. I absolutely recommend this place for anything auto related! Thanks Ali and the team!

Ali called the parts/supplier right away and was told to come back today 09/20/25. At the same day Ali was able to fix our vehicle right away.

Very grateful to Ali and his worker (I wish I got his name!) We had an issue with what we thought was the transmission. Ali ran the diagnostic machine to discover all was in working order and that the shift lever was the culprit. We had called the dealership to see if our car was still under warranty and got a quote from them (because it wasn't). They said the part wasn't sold separately from a whole new transmission-- 6600 parts, no labor.
Ali sourced the part (for a lot less) and saved us from selling our car and going carless. So grateful! He was quick, friendly and truly helped our family. We found our new mechanic.

Been going to this shop for a long time. The service is great. They make you feel like you are family. The prices are great. Went there yesterday just because my check engine light came on and they helped me put right away. They put the computer on the car to check the problem, was very helpful with the diagnosis of the problem and advised me it's most lively a dealer warranty problem. They could have charged me to do the work but was very honest with me and that goes a long way with me. Thank you for being honest and the service you provide when necessary. I definitely recommend going to them for any work needed on your vehicle.

I’ve been coming here for years. I’ve also recommended quite a few people here and they have had the same experience as I. Ali and his team are professional and honest. He takes the time to explain things to me and as well, he takes my financial concerns serious and comes up with different options to make repairs affordable for me. It’s been a tremendous blessing having them there. I highly recommend! -Alesha

I recently took my car for a brake and oil change at A&A Quick Fix, and I couldn't be happier with the experience. The staff was super friendly, and Ali took the time to explain everything that needed to be done. There is no pushy upsell, just honest recommendations. I highly recommend them to friends and family.

I almost never give reviews but I'm making an exception for Ali.
I was in a little bit of a hurry to get my car repaired before a state inspection. Ali told me to bring my car to his shop and he'd take care of it. He told me up front what cost, time and labor would be. Afterwards he checked my entire car and advised what needed additional repairs. He's honest, reliable and so nice to deal with. I'd definitely commend him to friends and family...
