5MGE is now running, (using the shorted fuel pump check connector, as afm has been replaced with map)
when throttle is applied, engine dies/chokes and revs drop dramatically, if you apply the throttle very gently it can speed up. revving the engine constantly results in what seems like a backfire through out the intake...
i think the engine could be drowning in fuel, exhaust is spitting out liquid (could be fuel not sure), and smoke is coming from exhaust manifold (could be unrelated )
As Jason mentioned it could be a timing issue, but that's easy enough to check. My money is on a VAC LEAK causing it to lean out. Pay special attention to the area between the throttle body and the AFM; I had a leak there once on my 6M and it did exactly what you're describing. Took me ages to figure out what it was because the leak was in a hard to find spot!
just had a thought, there is a large pipe connecting the egr system to the 6th exhaust port, it was undone, and i just tightened it breifly with fingers the other day, could this be the source of thou evil woringdoing vacuumus leakus
timing will be checked soon enuff too tho.
afm is gone tho, now using map.
