Maybe it will help

Hi, yes it is a tbi. I tried cleaning egr and it didn't appear to have any problem moving. Dont know where or if this model has an egr solenoid. It has a vacuum hose coming out of it. still researching this one.

I want to see this beast. Got any images?
Because when I'm ready, I'll dump the 4.3 when it's due time.
I might go to a lighter weight V8 like from a Lexus or Beamer.

My son has a 91 s15 that stumbles on acceleration. I have replaced the fuel regulator, fuel filter, replaced plugs, check wires for continuity, replaced o2 sensor. This vehicle idles fine until it reaches running temp. then it stumbles severely on accerleration and then throws rich fuel mixture on the o2 sensor. How much fuel should one see coming out of the injectors into the throttle body while it is idling. This one seems to be alot. I can see it covering the walls and plate pretty well just when idling. I tried to test the tps and the ignition coil and the ignition pickup inside the dist. but not sure if I am doing it right. Any help would be appreciated.

1988 Chevy S-10 2.6 V-6 4 wheel drive.When I
drive the truck for 30 minutes I have to keep my
foot on the gas a little, because If I don't the
truck dies, and when I start it up it acts like the
battery doesn't have the volts, but it only does
this when the engine is normal temperature.
Please help me out on this!
