Check for vacuum leaks around the intake. Make sure fuel pressure is within spec and the regulator is working properly. A common problem was the intake gasket. So check that closely. Expecially around the rear of it.

Thnx alot! Will try that tomorrow. You guys are great will recommend to my friends

Did you mean the intake gasket wher it bolts to the block or where the carb bolts to the intake? And what would the fuel pressure spec be for that? Thnx again!

9 to 13 psi and check both areas for leaks

Checked everything you said. No luck. Could it be an o2 sensor? Or throtle control sensor? This thing is workin my brain! Lol!
