I need some quick assistance!!I cranked the car and it started putt-in then started shaking and blowing white smoke!!Iy was driving fine yesterday.I was leaving to my girlfriends birthday dinner and she lives 30 min away!!..what bad luck any ideas?i hope it's not the diff or something.

 

Sounds like the ecu went out....my did the same thing awhile back.

 

I read something about that but,this car only has 110,xxx miles.it's a 93' any other ideas?How would I know for sure if it is the ECU?don't think it's the head gasket cause I just cranked it for the first time today drove fine last night.

 

check your vacuum lines. also try unplugging the maf and running the car.

 

Now it's not shaking as bad but,I rev it up a little it still has some white smoke to it.It idles a little better now but,still has a slight putt to it.

 

How does the exhaust smell? Is it running too rich . . . Smells like gasoline ???

 

I thought it smelled of gas but,my dad says different.It sat for about an hour while we checked here and there and I cranked it again and drove it while it smoked for a couple min and now it seems fine?The only thing I can think of that I messed with was I switched the heater vacuum hose back the other night cause it's 97 degrees out here so in the winter I have temporary heat. but,I don't think that would cause it.Should I be worried about it happening again?

 

IDK, but why not try switching the vac hose back again and see if you can reproduce the problem?

 

ecu.....fine one sec, back to smoking and skipping the next...borrow a injector test diode from a garage to verify. When it's smoking, one injector plug (or more) will keep the light on continuously instead of pulsing.

 

Well I did swap the VAC and let it sit overnight and it didn't stir any problems.I filled up the tank and I've been driving it now for a few days with no problems.I don't know what caused it but,I hope it's not an early warning.

 

Wrap it in a blanket, turn the heat on, feed it some soup.

PS- The vac hose you switched caused blowback in the intake. Most likely all of the blowback was PS fluid. The intake pressurizes the PS switch and it reverses flow when you do things like that. "Equal and opposite reaction".

 

So I wrapped it in a blanket,turned the heat on,but,it spit the Cambells out and laughed at me....O.L.T your right on the money after some deep thinking me and my friend looked at everything closely today and realized it might have been the PS fluid because of the vacuum,intake etc.Thanks a lot though it obviously just burned it off so it's running straight now.Next figuring out my weird camber problem.
