No it hasn't stalled I had a misfire in cylinder 2 and 3 before I got my coils changed po302 was my code Mechanic's Assistant: What is the make/model/year of your car? 2004 Toyota solara coup 4 cylinder Mechanic's Assistant: Are you fixing your Solara yourself?

Hello, and thanks for your question. My name is \*\*\*\*\* \*\*\*\*\* I will do all I can to help. Did you put all new coils on it? also is this Solara a v6? or 4 cylinder engine? and do you still have the p0302 code present now? Thank you.

I keep answering the same question yes changed all 4 and it's a 4 cylinderNot sending anymore more they trying to figure out why I got double charged now so no thanks

No worries, customer service is on the duplicate questions, Alright, did you also replace all of the spark plugs? If so, either the tech accidently may have cracked a spark plug when installing, (I've done it before) or possibly got a bad coil pack. But, it could also need a fuel injector, or the engine has lost compression, So to diagnose it properly, the technician needs to pull the plugs, and perform a compression test to check the base engine, all should be around 150 psi or so, then check the coil pack with a spark tester and make sure it's firing the plug, if it is firing the plug, then I would try another fuel injector. Thank you and let us know if you have any further questions.
