When is raining or snowing and the car is running the revolutions of the engine start going up and down adn when I stop, the engine light lightup and the car die if I don't keep it accelerate or changed to parking. Is the only way to keep it running. This not happend when the roads are dry. All this happend when is wet I took the car to the shop but nothing was found because was dry already.

Can you get teh check engine light scanned for codes that would really help.

With the engine running at night you can check to see if you see any sparks.

With engine running on a warm dry day spray salt water mixture slowly on the electrical components untill you see electricity arc through the mist or the vehicle starts to hesitate.

Let me know what you find.

I took the hoas eoff the egr valve. And it did not stall the other owner said he put a brand new egr valve on with I can see it is new. Do you think it could be the throttle position sensor. My check engine light iss not on. Thanks for your help

I have a 1995 chevy truck Silverado 305 cu. In. 5.0 liter. The problem i'm having is: The truck starts normal, it idles for about 5-& seconds than it dies out. It has a (DTC) 54 which says is the fuel pump circuit low voltage, or the EGR system. When I turn the key on I could hear the fuel pump go on but it stays way longer then 2 seconds. I have replaced fuel filter, fuel pump, idle air control valve (IAC), cleaned inside the throttle body with throttle body cleaner using a piece of rag on a stick. It starts than it drops to about 2000 rpm's, it shakes than dies out. Your help would be great. Thank you

Sounds like your truck is likely loosing prime. Check your under-hood fuel delivery system by tracing your lines from the fuel filter housing to the CP3. Did you do any work on the truck recently? I had a similar problem and found a loose banjo bolt on the Fuel Injection Control Module (FICM). Look for any wet spots (diesel) around your engine bay, in the engine valley, and on the sides of the block.
