We drove bigturbo's car around somemore today after setting the tps..
Still bucks on the low end, still WAY low on power. Compression is still at 80psi on both rotors. And the overflo coolant is bubbling, but the coolant guage doesn't read hot... Stock fan and shroud setup. Maybe the coolant ratio is off? Or are the coolant seals shot? But there is no smoke, car is still having flooding problems and won't hold an idle..

If the coolant seals were gone, that wouldnt cause the loss of power...my '88 NA motor's coolant seals went and that thing still had great power, just smoked real bad and overheated.
like JD said..its probably a vac leak somewhere, MAF could be bad...who knows, this is that motor that took a **** out of the exhaust isnt it??? lol.

it's kinda hard to test for vaccum leaks cuz my exhaust developed a leak in process of putting it back on, and i have to hold the pedal down to 2k to keep her alive. after 2.5k and up is revs smooth but no power. under that it sounds like it is stuggling hard, u should see me drive it around, it sounds like i got a bridgeport or somethin, yea but **** is really pissin me off!

Make sure the intake tube is tight and stuff like that. If it won't idle have somebody hold the pedal down so its around a grand and then spray some starting fluid, carb cleaner around the engine. I had the block off plate on the egr leaking bad once so don't forget to spray down around there. Might want to check the timing and reset it. I don't know man, maybe your car will shoot some diamonds out the exhaust next time, lol.
