I might have posted about this problem before but it looks like it got worse. The past week I have been having a crazy *** problem.

Lets say I'm driving around, I don't know whether its related to how hard I push the car, or what, but lets say I push in the clutch, and it usually bounces off 0 rpms and comes back to 900. Now when I push in the clutch, it bounces, and sometimes the car just dies out and warning light comes on. So I have to pop the clutch to get the car going again. Or other times it will bounce off 0 and the warning light will flicker, and it will bounce back up to 900. I have no clue whats going on. Car is running strange as well. Doesn't seem to have the umpfff.

You mean that if the car is in neutral and you rev it, the revs will drop down below idle and then pick back up?

Back out the idle screw a turn or 2 (make sure threads are still engaged) and see if that makes a difference.

Idle screw or you may want to check the ISV and it's vacuum hoses.

Ok, lets say im in a gear and driving, I push in the clutch, the rpms will drop as usual, but when it bounces off 0 it will give me a warning light, and it may sometimes just die out completely. If the die cars, I pop the clutch, car starts back up. This happens usually out of nowhere, but now its happening more often.

What rpm's does it idle at?

v944god

At 900-1000 during idle.

hosrom_951

That is when the car if cold or warm?

That more/less sounds like a vacuum problem or the ISV. Does it make a difference with the a/c on or off?

v944god

hosrom, iirc it should be during hot, cold might be 1000.

This problem happens with the A/C off.

Also, the boost doesn't seem to be the same either. Feels like there is a restriction.

Now, someone here (don't remember the name ) is going to comment me on this.....but sounds like a vacuum leak

Did you try setting the idle by bypassing the ISV when the car was hot?

Here is a link to show you how:http://www.clarks-garage.com/shop-manual/fuel-08.htm

If that doesn't help, check the intake boots on the IC, Turbocharger J-boot and Throttle boots.

Here is a picture of the vacuum line diagram that should help:

hosrom_951, i appreciate the help, only problem is i have no idea how to work on the car mechanically.

i agree with adrial, my car did the same thing when i tightened down the idle screw too much. see if you can back it off a little (flat tip screw driver, easy enough to try). might also have a major vacuum leak?

My friends toyota has a bad o2 senser and it about dies when he pushes in his clutch. Car also sounds kinda different. Maybe this is what could be wrong?

v944god

Ok, it looks like the car is not boosting at all now.

I tried getting on it, but all I get is loud farting sounds. I tried break boosting hard and nothing came, all I got was hard jerking. Seems the turbo pump is out too.

hosrom_951

V944god: Its fine now?

I was worried like you about mechanical problems. But it turned out to be 'plu and play' with the vacuum lines, except for the ones underneath the intake manifold.

Give it a shot with the diagram..........it's REALLY simple

v944god

Alot worse, car has little or no boost at all.
