SOURCE: egr valve is bad on my 1989 chevy with 305

You block it off before the valve on the metal pipe that runs to the EGR valve. The problem is that when you go to get it smogged you have to replace the EGR or it will not pass smog

SOURCE: Electronic Control Module Installation 1994 G20 Chevy Van

I just had the same problem. If it is a regular van try under the driver seat in a plastic box. If it is a conversion van try in a pannel just behind driver seat on side of van wall behind a pannel that looks like a vent.

SOURCE: Chevy 454 back fire

Ignition timing is set by the computer as long as the distributor pickup point is within reason.

It could be running too lean. One of the TBI injectors may be sticking or not working (wiring or computer problem), or fuel pressure could be low.

Where would I check for airfow and vacuum problems in a 1994 chevy Astor van.


Under throttle body. Take a can of carb cleaner(make sure you don't have plug wires breaking down) spray under throttle body if it changes the way the engine runs you found it. Egr and pcv are other less likely. Should be getting a lean code if you got a vacuum leak

1994 chevy lumina van. It will start and idle but stalls when gas


Try replacing the throttle position sensor. I had the same problem in my truck. It would start and run for a bit but as soon as you let off of the pedal, it would die. Try it and see if it works.
