Guess what folks, my car is once AGAIN misfiring, here is my original thread

http://www.2carpros.com/questions/chrysler-sebring-2004-chrysler-sebring-p0301-code

Now everyone kept telling me to change my engine, I did!, and here we are again with the misfire. This time its in cylindar 5 and 3 (P0305, P0303) and it throws the generic code P0300. Anyone have any idea's since it now has a new engine? And its not any of the basic stuff, like changing the spark plugs, oil, coil pak etc... I have tried ALL that in the past. It seems like the only thing left is the computer itsself, because once AGAIN there are NO signs there is anything wrong with the car, no stumbling, no hesitation, nothing just the pretty little light saying there's a misfire!

There are many causes for engine misfires. Check your fuel pressure it HAS to be 58psi +-5psiso 53-62 psi. If it's below that it may beit. It als o may be the ASD relay-automatic shutdown relay. It's inthe power distribution center. I am sending along other things that can cause this.

Okay, mechanic says it could of been moisture that caused the light to come on, because it came on the day it rained and now has turned itsself off. Is that even possible? I honestly think my mechanic is stumped like I am. I believe he already did the fuel pressure test, but I will ask him about it. Thanks for being helpful!

Ya I could beleive that, as I had a chryslerproduct many years ago that when it rained it ran like crap, so I got a new computer for it and itfixed it. It wouldn't surprise me at all. Hopefully it's fixed.

The chrysler 2.5 are notorious for having distributor issues. They throw a misfire code and a crank sensor code which is inside the distributor. Buy new distributor and problem solved!
