Hello;
Make sure the distributor wires are hooked up and making a goodconnection at the base of the distributor. Also make sure the coil wire is fully in the socket. Make sure no wires got pinched for the relays. Hope this helps;
Thanks;

How to test an egr valve on a 94 topaz


Apply vacuum with a hand held vacuum pump, the engine will stall out or run really rough. If you have a very rough idle wet your fingertips and touch the lower part of the valve , if it is leaking then you will hear a sizzle and the valve will be very hot, replace the valve..

I have a 96 chevy blazer with a 4.3 vortec rough


Do a compression test on all of your cylinders when it is cold. Backfiring is a sign of a worn valve seat allowing mixed fuel and air (lit by spark) to be forced back into the intake. You will probably see compression loss on one or more cylinders.

Also... there is a chance that the EGR valve is not totally seated when the engine is cold with just a small blow by. The EGR valve seats coke up over time with black gunk.

I have a chevy blazer 94 S10 still quit on the road.


How is it running before it quits onyou. This could be the culprit of an egr valve. How many miles on thevehicle. The egr seems to die on a certain mileage pattern. Also youcould start by cleaning the egr valve before replacing it. This couldvery well help the situation, but this is just a guess. Hope thishelps!!

My 94 s10 4.3 vortec was running very rough


I hope this helps, I have had this problem 1 other time.
The EGR valve you bought was a negative and it calls for a positive. Or visa/ verse. If that is the case, it will not start. There are 2 different EGR's for 1994, CFI & TBI, both are the type of injection and are not interchangable on the EGR valves.

Idle problems


if it is a vortec 4.3l they were real common for egr valve problems. you can remove the egr check for carbon stuck in the plunger. after cleaning reinstall with a new gasket. New gaskets with a screen are available to keep this problem from happening again the standard part number is VG57. When carbon gets stuck in the egr valve it causes a vaccum leak and rough idle. please rate this if it helps
