I have a 1995 Neon that randomly likes to stall. It starts right back up afterwards. I checked the fuel pressure at idle and got 49psi. Recently replaced the plugs and wires. Sometimes you feel it studder (miss) when driving and the acceleration is slow sometimes.

Any Ideas??

Thanks

Whens the last time it had a tune up?. Check fuel pressure while you give it some gas to make sure it don't drop off at all. Any CEL lights, auto or manual trans?

 

I just replaced the wires and plugs. Air filter a few months ago. I checked the fuel pressure at idle then turned the car off and it stayed at 49 and slowly dropped. I started it back up and kept a close eye on the pressure until it stalled. It never drooped below 48, even after the stall.

 

Almost forgot...auto trans, no CEL, only a 55 code from the key dance.

 

Revved engine and no loss of pressure.

 

Double check the wires to your sensors (O2's, crank, cam, primary coil) for cracks, rubs, etc. They can cause the issue you report especially as they age.

 

Does the car ever seem to take longer to turn over after its been sitting? If so this could be a faulty regulator or pump. Does the idle ever seem high, or bounce? This can be caused by a vacuum leak or faulty TB sensor. Usually cam sensors will throw codes, but the crankshaft sensor wont. Crankshaft sensors can sometimes cause it to kill. I usually start by unplugging it and cleaning the pigtail. The plug is facing upwards and can catch oil from a valve cover leak over time. If this does not help, I would be checking wires. A loose or faulty connection somewhere can also cause it to randomly die. Keep checking the codes periodically, wouldn't hurt to actually scan it and make sure there are no pending codes. Will the car only stall if your accelerating?

 

It finally gave me a code! I got a 12 and 32. I didn't disconnect the battery so the 12 doesn't make sense. Any hints on troubleshooting the EGR valve to fix code 32?
Thanks

Buy the EGR block off kit. I used to just leave it there and block the vacuum lines, it always worked for me. The only way the EGR will make it run differently is if the diaphragm is bad causing vacuum to leak. It could be an issue more usually EGR doesnt change how it runs. If you have a scanner check your TPS sensor to make sure its responding to the pedal movement how it should

 

The code 32 means a shorted or open EGR solenoid (transducer). Does anyone know what the resistance should be across the solenoid?

My HAYNES manual states the solenoid and valve should be replaced together. But, i can buy just the solenoid through the internet. Can i just change the solenoid (transducer)??????

I don't know where or if I should buy a block off kit. Where is one available?
