Well if your pumping the brakes rapidly it could cause that effect as the manifold has to keep the reserve in the booster at low pressure.
Your basically creating a vacuum leak as you press the brakes.
If it were my motor, i would pull it and do a full rebuild rather then playing with unknowns and someone elses mistakes. This is what i did with my engine.
The block would have to be VERY warped to cause such a leak with a stock gasket. Ive seen composite gaskets seal some nasty looking...
Are you sure you have the cam timing correct? If you put in oil and it didnt change it would be time to rebuild the entire engine. No compression is a rings and/or piston problem assuming cam timing is correct. The block would have to be REALLY warped to lose that much compression.
Just to make...
For the CPS connector im using a MSD connector. Its very easy to crip and its a very nice quality connector. It can be had here http://www.summitracing.com/parts/MSD-8181/
Very nice piece.
Check for codes, if you slowly let off the gas does it try to idle at allot just completely die?The throttle plate is for the most part completely closed and idle airflow is almost entirely dependent on the ISC valve.
You can test it using the tsrm procedure.
