ok 94 s10 blazer 4.3 cpi 4x4 what happens is that once it gets to operating temp it runs like crap, spits sputters even stalls out will start once cold any one have any ideas on where to start or have a fix ?

 

bump? need more info ask

 

Please be a little more patient. The rules of the forum state to not bump a post until you have waited at least 24 hours.

In that extra time you could have run a few searches and/or tried some things yourself and reported back on what you have already done instead of seemingly sitting on your hands waiting for someone else...

What have you done to try to correct this problem?

Did you check for codes? Were there any? If so, what are they?

When was the last time a tune up was performed (plugs, wires, cap, & rotor at the bare minimum - upstream O2 sensor if it never has been done before)?

All of these are pretty basic questions...
