Need a little help on this one

I removed my turbo boot today,to give a good cleaning.Put it back on,started it up and now it runs like crap.The car won't rev and stalls out.There is alot of white smoke coming out of the tail pipe.

The car was running just fine before i did this.Now i'm thinking that i put the afm connector in the wrong way.My car isn't with me right at the moment to check the afm connector.It's just strange that my car is running like this.Anyone know what the problem might be?

Double check everything... you may have left off (or left loose) a connection or hose.

The AFM connector only goes on one way.

Had you driven the car earlier that same day? Or when was the last time it was started?

I drove the car last week and it ran just fine.I started it up before i removed the boot and the engine ran smooth.It seems strange that the engine would run like this.

So it was WHITE smoke? Not blue at all?

Did you touch anything on the turbocharger?

Just white smoke.I did move the wastegate hoses a little bit, to get the boot back on but, the two hoses were connected.

What did you clean the hose out with? Could be just that it's ingesting some of the cleaner kinda like when you run ATF through the motor. Check your plugs to make sure they aren't fouled. If they're ok, I'd check for leaks as well since the rubber boot doesn't seal very well.

That's actually a pretty good theory on the smoke. Pretty much any kind of cleaner, Brakleen, Seafoam, etc seems to burn out white if you get enough of that in there. Check to make sure you connected the boot back up properly, and then make sure you that you reconnected the couple of vacuum lines on the AFM to Turbo piping. There's a line for the charcoal canister, a bigger line that runs to the VCM, and the huge line that runs up to the valve cover. Since they're not in plain view it wouldn't be hard to forget these.

I only cleaned the outside of the hose out.The one thing i forgot to mention that there was white smoke coming out of the engine bay.This leads me to believe the turbo boot wasen't sealed properly.

Telling us CORRECTLY what is going on helps. Out the engine bay & out the tail pipe are two completely different things... Was smoke coming from BOTH the exhaust & engine bay????????

Maybe you could look for where the smoke is coming from? Just an idea....

Sorry for the confusion.When i first started it up smoke was coming out of the engine bay as well as the exhaust.I forgot to attach the breather hose.after i attached it,started her up and the smoke was only coming out of the exhaust.

Well white smoke usually means it's burning coolant. I'm not sure what would have changed by just messing w/ the turbo boot, but you should probably pull the spark plugs and look at the tips to see if they are oily or covered in coolant.

Did you get a whiff of the white smoke smell? That can tell you what is going on too... a very sweet smell is coolant...

There was no sweet smell in the white smoke.I think the turbo boot may not be fully connected.I'm going to work on the car tomorrrow.Like i said ,the car was running great before i removed the boot,And i haven't put more then 150 miles on the car after the turbo swap.

I'll carefuly inspect all of the vacuum hoses as well.

Well, i went to work on my car today and checked everything over again.All hoses were hooked up and connections tight.The turbo boot was on the correct way.I went to start the car up and no change.

The white smoke is still coming out of the engine bay as well as the exhaust pipe.I'm going crazy trying to figure out what the problem is.All i did was take off the turbo boot.The car was running strong just last week.I timed the engine correctly as well.I only took it out for a two mile drive and didn't race the engine at all.

Like i said before,the engine ran fine just before i removed the boot.I did check the boot for cracks and not a single one.I think my timing may have got out of whack.Any other advice on what maybe the problem?

Did you check out the spark plug tips? Is the exhaust spitting out any colored liquids?

Yes, sorry i didn't mention that.The plugs were fine and no colored liquids coming out of the exhaust.Just the white smoke.I thought my timing could've changed in some way,but taking off theturbo boot probably and afm woudn't have any effect on the timing.

It seems like we're going in circles. It would be helpful if you were more specific and descriptive when talking about what's going on. Right now I have to guess what you mean / did / checked every time.

So you attached the breather hose the first time, and the smoke went away in the engine bay... but now it's back even w/ the breather hose still on?

Are you letting the car warm up to operating temp? Does it overheat? Is it leaking any fluids anywhere?

Like I said before: white smoke means it's burning coolant. The only time I've seen white smoke and it's not coolant, is when it's burning ATF (long story).

White smoke = burning coolant
Blue smoke = burning oil
Black smoke = burning too much fuel

Sorry for going in circles on my problem.Yes, smoke is coming out of the engine bay again,with the breather hose attached.No liquids leaking anywhere.I didn't let the car warm up because i worried about damaging the engine.

I have to keep my foot on the gas to keep the car from stalling out.The engine still stumbles and won't rev.Why would i burning coolant all of a sudden when i had no problems just before i removed the boot?Thanks for taking the time to help me out,and i'm sorry for not being more clear.
