I have a 93 chevy blazer Vortec engine, check engine light just came on, I've been driving it for over a week, just now had this pop up? Any ideas? I was driving fast today trying to get somewhere in a hurry?
I have a 2003 gmc envoy can any one please tell me where the EGR valve is located???
Thanks feel free to email me dh11670@charter.net.
I have a 2000 S10 4.3. Have some driving issues, but idles fine and no problem with breaking. I noticed most complaints are 0n 94 - 95 - 97 motors, has GM changed the design or what. I saw no post on 2000 or newer.
I own a 94' S10 Blazer with the Vortec engine. I have owned 2 blazers, the 1st had the TBI 4.3, never had a problem.
My Vortec has had all the same problems listed in the forum. I've replaced the fuel pump twice, the CPI, spark plugs, EGR x 2 and have cleaned the upper plenum and EGR several times. I have not tried the mesh gasket or using a higher grade fuel, but after all the reading I definitely will.
The problem I have had lately is my engine running hot, and coolant spraying out of the upper radiator hose. I have tried replacing the hose and it did not fix the problem and just recently I changed out the Thermostat thinking it was not opening. After all this work the coolant still leaks, thinking the radiator now. Also my truck will not start now, It had been acting sluggish when starting recently. The plugs are new, about 3 months old, but I did not replace the distributor cap, could this cause the problem of not starting?
This board is very user unfriendly because one can't respond to a specific posting unless the original poster left his email.
I have a 94 Jimmy 4.3 with some of the same problems. My idle is great and it seems to run great for about 20 min. When I stop and accelerate it dies and stalls out. I have to get out in traffic and shoot starting fluid in throttle body. It starts up, but very sluggish. Only happens when I give it the gas. Thanks brureb28@aol.com.
Grrrrrrrrrrrrrrrrrrrrr.
Time to clean the egr again.
OK I have a 94 gmc jimmy it seems to have a egr going bad. But I have a stupid question. do I have to remove the intake to get a better hold on this and should I use this fancy fiber filter gasket?
2/25/08 I also have a 94 4.3 blazer with many of the same problems listed in this forum, I must say I'm a little discouraged by all the bad luck everybody is having. Would like to see more info on the egr upgrade in the ECM that one follow talked about.
I have a 1994 S10 blazer, and I just removed the egr valve again. I put a blank plate on and it runs great. 2 years until emission testing. Have to go get my egr valve and my sledgehammer now, its the only way to fix this problem.
This page is helpful.
I have a gmc jimmy 94 with 126000 miles. I had to change the fuel pump and sending unit and I also changed the oil pressure switch. it will crank for ever and start for just a second or two and then die! does anyone have any ideas on what else I can check before bring it to the mechanic shop?

1997 GM 1/2 ton 4.3L. Starts okay, but it runs very rough especially when cold. If I accelerate hard it runs good. When I get to cruising speed it runs like garbage. It has a 5 speed so you can really feel the jerking motion of the engine running rough. IT eats distributor caps. The contacts get corroded almost instantly. Replacing sometimes makes the rough running go away. I bought it for $1500, and only drive it once or twice on the week-ends, so I guess fixing it is my new hobby. Could be worse, I could be drinking instead.
I think I might make an EGR cover plate as mentioned earlier. I might create more NOx, but hey, I only drive it 10km/year.
