    Wierd Problem

    I have a 02 Rex with a intake exhaust and bov. When I drive and come to a stop my rpm drops down to almost 0 and my car jus dies. I was hoping someone can tell me what the problem is and how to fix it. Thanks.

    Welcome. Put your car back to stock. See if the problem still exists. Consider it troubleshooting completed.

    +1, its probably your mods without a tune thats messing your ride up. Especailly that intake and bov, exhaust not so much. You'll probably want to read all the stickys on here as far as what to mod before you buy stuff. I did the same mistake but put it back to stock and it fixed everything before I broke anything. My advice is go with EM, oh and go back to stock.

    You might want to think of either selling those or trading or just buying them. Cause its probably goinng to stay the same untill you fix it.

    Sell the parts and buy the stock parts.
    1) Your stock airbox already supplies more air than the engine can use so your new intake is costing you power and introducing possible MAF issues and
    2) BOVs are bad and cause problems unless your car has been highly modified and tuned to support one.

    +1 bov do help if you are tuned for one, if not they disturb the air/fuel ratio during shifts and at idle, sometimes. if ur tuned for one it will help with keeping ur turbo spooled up during shifts.

    Push in the clutch? Just a thought, LOL! Just kidding bro.

    I once had a '90 Plymouth Laser, and it used to die when I came to a stop...the engine ended up blowing a head gasket, but the car was a POS from the jump...

    I am sure the other responses are correct, return your car to stock first...good luck!

    On DSMs idle speed control is actuated by a stepper motor. The ECU cannot know what "step" the motor is on, so when the stepper solenoid fails the ECU just keeps on sending a "move xxx steps" signal to no avail. There are other reasons they won't idle, but in the long run, as you've probably concluded (I certainly did with mine...) the car was doing you a favour...)

    but the car was a POS from the jump...
    Been there, done that, agree! They're great on paper though and when they do run they're terrific cars for their time period.

    Yea, if it had been brand new...it might have been better, but it had a few miles on it...like 120k I think...got it in '97...

    It sure did grab alot of attention at the midnight races though, especially since I had an intake on it...sounded nice and throaty, but it was all show and no go, lol.
