Turbo II - Rough idle, smoking, choking under accelleration.
Okay.
First some background for anyone who hasn't already heard:
It's an '87 Turbo II with a fresh engine from Mazda with less than 600 mi on the engine. Everything is stock except the HKS intake, the Racing Beat downpipe and the straight exhaust into APEXi N1 Duals.
The idle is now relatively steady give or take 200 rpms, it is idling around 1250. It still sounds kinda rough though.
Secondly the smoking is definitly noticeablle. It doesn't really stink like burning oil or coolant, its a light colored white/blue smoke. It doesn't seem to smoke as bad when you rev it up but once its revs down it smokes again. The engine seems to be running okay though, it isn't shaking or stalling. My dad says it might be running rich.
Thirdly under moderately hard(spirited) accelleration it kind of misses or bogs down or something. It starts to pull quite nicely but then, right when rotarys start to really shine, it just has no power and misses. You can feel the car just lose power when it "misses".
I'm thinking these issues are all related. I'm guessing the TPS needs to be adjusted....but I really don't know. Its needs a new blow off valve but this wouldn't cause these symptoms right?
My major concern is the rough idle, the smoking and the power loss under hard accelleration.
Here is what has been replaced : all vacuum hoses, belts, lights, motor mounts, gaskets, lines, injectors, seals, plugs, wires, battery, alternator, brake master cylinder, clutch, p-plate, throw out and pilot bearings, rebuilt rear, Racing Beat downpipe, new 2 inch y pipe into APEXi N1 Duals, fuel filter, diamond cut headlights, o2 sensor, factory stereo, HKS intake, tires(less than 500 mi on them), brakes and wheel bearings.
There is also a "screaming" or screeching sound that comes from the read end when you give it gas while driving.
Please reply with any/all ideas, comments, suggestions, questions or ideas. Thanks alot guys. I'm gonna see what else I caqn find on the forum.
