88 S-10 help

[cstein]

I have an 88 S-10 p/u 4x4 4.3 5 spd that I'm having a reoccurring problem with. When the engine gets hot and runs for awhile, it sputters when I try to accelerate. Changed the fuel filter & pump, gas (to 91 or higher octane, no ethanol) and most recently (3 mos ago) had the ignition module? (looks like a cassette tape) replaced. That worked great until today, problem is back. My readings on the battery guage say it's about 16-17 volts. I heard possibly the engine ground is bad ?????????

Thanks ahead of time !!!

Engine ground is possible, also check the fuel pressure. If the fuel pressure regulator is going bad it can act like that as well

Thanks,OBP,

My mech said the same, he checked and all was OK. He did r/r distributer and p/u so we'll see. Thanks again

OK, have now r/r distributor and ignition p/u. Also tuned up. Still having problems. Seems to be sputtering at different times, 5th gear, going uphill in any gear, or trying to pass someone. PLEEEEAAAASE HEEELLLP! OBP sent you a message, tryin to get a consensus. Do you all think it's the fuel pressure regulator ???????? If so, where is it and I'll try to fix the thing myself, tired of paying to get it "fixed"

Check all vacuum lines for leaks and look at choke valve when cold and warmed up.
