My 87 turbo was running good, and I was driving normally when it stalled out at a light. I tried the unflooding trick(which has worked before), but nothing. After several tries to get it started, I did, but BARELY. I had to hold the gas to keep it going. My friend said it seemed like it was running rich, and every time I try to start it, smoke pours out of the muffler. It was mainly whiteish-blue smoke and a little black at first. I just got a compression test done and my numbers were good. Anyone who can help me, please do ASAP!!!!!!!!

Anybody??

My car never holds idle when I start it up. I have to hold the gas until it warms up a bit and holds the idle. Then I have to keep letting it warm up even more or else it will stall if I put it in gear, drive a tiny bit and go back to idle (like reversing out of my driveway, then having it stall when I go to put it into first). And my car blows whitish smoke every once in a while. It's kinda rare and pretty random when it does blow smoke. Sorry, I don't know what the problem with your is, but it sounds similar to what's going on with my car, except much worse.

Oh, and bump.

Notice any lack of power?

I can't drive anywhere, of course there is a lack of power. I tried starting it again, and it will start, but no idle....I have to hold the gas and it is VERY lumpy.....alot of whiteish-blue smoke. Please help me, I need my car!!

I would have to say....

COMPRESSION CHECK!!!!

Saku

I just got a compression test done and my numbers were good. My guesses would be an ignitor coil is done, or else my turbo(would explain the whiteish blue smoke). Any thoughts?

Def. have to do a comp. check to be safe...hope your engine didnt go on yea.

I JUST got a compression test done. Less than a week ago. The shop foreman at Mazda said the numbers are perfect.

check your air flow meter

no no no, check your PIPES! intercooler elbow blow off and did the same **** when i had stock ecu.

The whitish-blue smoke usually means that you are not burning enough fuel because your fuel injectors are clogged. I would check the fuel injectors. Hope that solves your problem.

Listen to what these guys are telling you. Check compression once more, yourself, right now. Sounds like the engine is only running on one rotor. This can be because of fuel, spark, or compression on one of those rotors. Usually, if an engien is working, fuel and spark dont just quit, but compression can. Rotaries are unlike any other engine in that they can have perfect compression one day and NONE the next on one rotor. They let go in a split second with no warning.

Pull your lower plugs and run the poor man's comression check. Open the throttle, ccrank it over, and feel for pulses from each hole, front to back, 6 in a row.

Verify this, now, and we will help you further. Dont rely on last week's results. This only takes 10 minutes, and once you verify this we can move on.

In order of increasing cost - possible causes include (but are not limited to)

An intake piping leak after the AFM.

A bad AFM. Mine acted exactly like yours.

Bad compression.

Thank you very much. I took off my intake/throttle/and the intercooler and piping and just cleaned it out and tightened everything back up, and it fired up. Running good now(except for my unknown hesitation problem, which is basically only in 4th gear at over 5000rpm). Thanks for the input(and thanks hypntyz7 for telling me how to do a comp. test without a tester...I didn't know you could do that)
