did a boost leak test and it leaks at the throttle body shaft...im ordering the seals now and going to install them...i am just woundering if any of you had problems with the engine stumbleing just from that?? that was the only thing that leaked from my boost leak test. i did a compression test and it was at 152 across the board...this is from a dry test on warmed up motor. other than that i know my ignition timing is not set exactly... could that be it too?? thanks
 
It could be a number of things, start by getting those leaks fixed, if the problem persisted change the plugs and wires.
 
yeah i know...there is lots of new parts on my car tho so im thinking its the boost leak...well i hope anyways... plugs and wires are new... i didnt get a chance to gap them yet tho, will do as soon as i pick up a gapper!

i dont think its fuel cut...im on the stock maf and only running like 11 psi
