i have a 1996 dodge neon that will run for about 20 minutes and then stall. i have had the coil pack, spark plugs, and spark plug wires replaced. have had the coolent sensor replaced .have swapped the pcm have had the camshaft sensor replaced and still the car will only run for 20 minutes. today i installed brand new spark plug wires and new spark plugs and the car will run for 20 minutes. i noticed after installing the spark plugs. that now the car tries to keep running first will almost stall and then it will rev up for 5 or so minutes and then it will finally stall

 

check for fuel issues. Is the gas tank full when you are running or half full. It kinda sounds like the fuel pump is heating up and quitting.

 

It just stalls out while driving? Have you checked vaccum lines and your EGR tube and valve? Any codes?

 

the fuel tank is either half full or 3/4 . so are you saying try the car on a full tank and that may hepl

 

if the fuel pump is completely submerged it will keep the pump cooler, but if you are at 3/4 of a tank that should be plenty. Pull the codes on it and see what it is doing.

 

im getting codes 44 and 43 . i tried spraying carb cleaner around the hoses no change. also i forgot to mention i had a mechanic troubleshooting the car for 4 days he suggested that it was the cam sensor after that he said there was still random misfire between the cylinders .and latter said that the main ground wire connecting to the pcm was loosing ground .it would go from low ohms while the car was off to high ohms once the car is running.

 

as of right now i have the car a haynes repair manual a small set of tools hoping that i can possibly repair this car. so far i have spent almost 600 dollars on parts and repairs in the past 2 weeks .

 

how do you check the egr valve . im kinda new to this repair thing . i recently bought the haynes manual after reading someones post on this forum

 

Pull it off and make the valve is moving correctly and not sticking. If you have the Haynes manual, it says how to in there.

 

ill give it a try. however it can be intimidating when one is not sure what they are doing .but i guess if i take my time and follow the step by step instructions ill be fine . any idea as to why the main ground wire is loosing ground to the pcm
