I have a 2003 Neon 2.0 SE. When I got the car every once in a while, once it was heated up, while driving you'd feel a small jerk and the car would pretty much lose all acceleration. The only way to get it to gain even a small amount of speed is to put the pedal to the floor. Now it's started to happen every time I drive the car, and it doesn't even have to heat up first. It's throwing the code for a weak fire from post 2 on the ingnition coil, but I've replaced it twice since October, when I got the car. I've replaced all the spark plugs twice, and the wires connection the plugs to the coil. A mechanic at Progressive said it was probably the computer then, so I replaced the computer as well, and the problem isn't fixed. Other mechanics said to replace the purge valve, PCV valve, and the catalytic converter, which have now all been replaced. I'm really tired of spending money on people takin' a shot in teh dark at what's wrong with it so if anybody has dealt with this and can help me out it'd be greatly appreciated. Thanks.

 

What is the exact code that it's throwing?

 

p0352, p2302, p2305

 

Sorry, I read the wrong invoice. After we got the computer replaced, the only code that was still there was p2305

 

So if you've replaced the coil and plugs and wires and the computer then the only thing that leaves is the wiring from the PCM to the coil...

UNLESS one of the parts you've installed is faulty.

 

Okay I'm pretty much a retard when it comes to cars so I'm gonna have to ask you what the PCM is lol..

 

The computer.

 

Never count on a brand new part being good. That being said, it sounds like you have a problem somewhere in your wiring.
