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!

start it up the starter tries to drag only when it dies.Please help me out with
a solution?

S10 unable to accelerate by mptimko

Hello to all, I come in search of a possible solution. I have a 2000 s10 4wd 4.3 V6 vin W with CPFI (central port fuel inj). Well I have a mind stumper. A few weeks ago, my fuel pump died on me for the 2nd time in 2.5 yrs. So, after much cursing and swearing, I bit the bullet and replaced the pump and harness, flushed the tank, filter etc. It ran ok for a day or two but then it started acting up. What it does is when you start it and go it's great for about 15 minutes and then all of a sudden you can't do anything more than just tap the gas. If you do, say going up a hill or even on flat, it just bogs down and if you geive it even more than half throttle, it backfires up thru the intake, not loudly, but enough. Kinda sounds like when you pull the choke out on your lawnmower and it starts flooding out. At first, you could pull over and shut it off, wait a min and then do it all over again, but now it's gotten progressively worse. I put a full tune up on it when I did the pump, and just yesterday it popped the code for a left bank o2 sensor so I changed that and looked for any vacum leaks but to no avail.. After looking at what else it can be, I have gotten everything from egr valve, throttle pos sensor, maf sensor, clogged cat conv. I am at my wits end cause it ran great until the problem with the pump and I can't go to the garage cause they will kill me on diagnostic charges. Anyone else had this problem????? Thanks for your input
