Stock 85 Camino
305 w/ Quadrajet

My car will not idle (have to always keep foot on gas) and it has terrible acceleration, takes FOREVER to accelerate between 1000 and 2000 rpm. However in park it revs just fine.

I have tryed unhooking the exhaust from the manifold, put on a different quadrajet, and taking all the emissions stuff off (back on now except cat).

Could it be timing, compression, fuel pump?

Any Ideas?
Thanks in Advance

Still sounds like there's still an exhaust restriction. Will the engine rev beyond 2000 rpm when it's in park? Some crud from the converter may have found its way into the muffler or is clogging the exhaust pipe further back.

If the exhaust system is in good shape, I'd look at the timing chain. How many miles on the engine?

120,000 miles, took exhaust off nothing.

I put on a fuel pump and spent half hour getting fuel dumped on me while lying in dirt today. That was fun. (the oil level was really high and smelled gassy so I thought it was the fuel pump) nothing changed.

COULD IT BE THE STALL CONVERTER? This would explain why it revs fine (for a 305) in park. Also it takes like 5 seconds after you shift for the trannie to shift are they related.

It's the stock 700R4.

It sounds like your symptoms are from more than one source..... very common.

I'd bet a weeks paycheck that your torque converter is the cause of the lack of idle and poor acceleration. You've lost the torque multiplication that is designed into the T/C. (It has lost the ability to slip, probably due to a broken fin)

You have probably already solved the cause of the gas in the oil, by replacing the fuel pump.

Pretty sure it's gotta be the torque converter, but I don't wanna spend all the money on one if it's not.

I can't find a vaccuum leak anywhere.

Any ideas/opinions/comments?

Yup sure sounds like it could be a torque converter..

I can't remember if you answered this in another post or not, but have you considered the timing chain? If the crankshaft will move back a noticeable amount without observing any movement of the distributor rotor, then the chain has stretched and may have jumped a tooth. If you had to adjust the timing more than a few degrees recently, it may have been due to a jumped timing chain.
