Re: Engine bogs and dies

hey brian, first off , i am definitely not an engine expert by any means, but , i just fixed an issue with my 327 that had been giving me a fit for a while. it was similar to yours, car ran good at idle , then ran like pure crap in gear. turned out to be it needed a valve adjustment. have you tried a vacuum test on it yet? mine would jump steadily from about 12- 17 . after i adjusted valves, it sits rock steady at 19 now. not sure if this is your problem or not, just sharing what fixed similar problem. good luck !

Re: Engine bogs and dies

Recheck your timing. Do a 'search' and there is a wealth of knowledge on setting both total timing and initial timing.

Re: Engine bogs and dies

set the timing with the brown pigtail wire disconnected, or your timing will be way off.what kind of car?usually the est wire disconnected will change base timing 4 to 6 deg if not mistaken.if you set the timing with the est wire connected b ut to the factory number, you are actually setting it 4 to 6 deg retarded.

Re: Engine bogs and dies

i hope you didnt use the 305 throttle body on a 350?
350 uses bigger injectors.
350 requires more fuel and if its computer controlled the 305 prgm doesnt work well on a 350.
