recently got engine codes p0300 p0301 p0302 p0303 so that means all of cylinders on the left side have misfired randomly together. the most recent work i have had done was in january. i had the timing belt (and all correlating parts) replaced as well as oil change, and spark plugs. I read something about the timing belt effecting another belt because of its new tightness? but the guy at autozone suggested that it could be the coilpacks needing replacement.

my other question is my system leaks refrigerant has anyone ever used the stuff called red angel a/c leak sealer?

thanks


it runs fine, no rough idle, everything feel smooth.

Clear the codes see if the problem persists.

 

i cleared them once tuesday and they poped up again yesterday, i had driven about 150 miles between them popping up again if that makes any difference but that was straight, i didnt really use the car much this week.
