Ok, as I expected, we are at the diagnosis portion of the rebuild. It's together and in, but it won't start. There is spark, there is fuel, and air.
The symptoms:
:Turns over fine, no fire
:Backfire through the intake (hot air through the throttle body, like the intake valve is open when spark occurs)
: Boost guages read spikes of pressure of 10-15 lbs (from the backfire, and the MAP?)
All in all, the engine sounds like it always did when it trys to turn over. When it reads boost, the engine bogs. I hope this is electronic and the cam isn't off. Help me guys, I'm almost ready to take it to a shop and tell them to fix it.
