heres what i got besides a headache............my buddies 94 chevy 1500 4x4 with a 350 tbi. has a sputtering problem. it does this from a dead stop to full throttle. all tune up parts have been replaced timing has been done and set to base. tps has been changed with an advanced auto parts one around a month ago. have not done a fuel pressure test. looking for some sort of a way to go.

 

did he change the fuel filter?

 

I have seen this subject come up many times in the S10 forum, "WTF?".
Check the wires and plugs on the injectors. They may be pinched under the air cleaner or one unplugged...

 

yes furl was changed. i thought the same as far as a wire pinched. pulled the air cleaner looked at the wires and they were good.the thingis that it has no codes. driving me crazy[sm=headbang.gif]

 

Can you see injectors spray? Maybe remove the ignition module and have it tested

 

Maybe rebuild the TBI unit? It could be crapped up. I've done mine, and it's a lot easier than rebuilding a carb.

 

Yeah one little piece of crap can funk them up.

 

tbi looks good, plenty o fuel. im gonna try a map sensor and see if that helps.but it didnt and that now proves i know nothing about chevy

 

turned out to be the dist.
