Just a note to let ya'll know, the problem turned out to be a bad Fuel Pressure Regulator and a plugged injector... mechanic isolated by accelerating engine while in gear and emergency brake on, engine was hesitating and missing, he then sprayed some kind of liquid into the Throttle body and the thing cleared up... total cost $300

Now runs like new, with so much power, its scary....

Thanks for inputs...

Hi All,

I have been having a problem with my 94 Blazer 5.7, Automatic, 205K miles.

No problem starting, but when started first thing in the morn, it idles fine, but once on the road, and I excellerate it hesitates and almost cuts out, no power. Once it warms up, it seems to get better. But has rough idle, and still hesitates on excelleration.

Things Ive done or had done. Replaced plugs (couple of plugs were vry corroded), replaced Air Cleaner, used bottle of injector cleaner.

Took it to the dealer, they put it on the computer and no codes showed up, the first time.

The second time at the dealer, left it over night so they could see the problem when cold. They replaced Dist Cap/rotor, oxygen sensor, and fuel filter. But I am still having the same problem. I am wanted to get a little smarter before going back to dealer again.

Any ideas????????


Help would be most appreciated!!!
