    Question 2002 WRX not running after heatup

    Bought the car new. It has been running perfect since but recently it doesn't run and no one around here has any answers.

    When the car starts it acts normally. The temperature gauge rises normally. After about 50 miles, the car begins to stutter or miss fire (it feels like) (quite a definite physical jerking) at high RPMs (4000 +) and the condition continues to worsen down to very low RPMs (2000) until the car does not have enough power to pull its own weight. As I slow down to 2 MPH, and pull over to the side of the road, the car idles at 750 dropping occasionally to nearly zero but not completely shutting off. I can rev the engine to 3500 RPM (weakly, it feels) but when I put it in gear, it has absolutely no power. I wait, go about a fifty yards and have to pull over again. Slipping the clutch, etc, I finally give up and walk home.

    I wait about an hour+, return to the car, and it starts up normally. If I drive less than thirty miles the car gets me around and seems to behave normally.

    I noticed a faint repetitive chirping sound the last time it stalled out.

    The local dealership has (expensively) replaced the oxygen sensor and the catalytic converter in an attempt to fix the problem, to no avail.Their repairs affect the problem not at all.

    As you can see, I am not a car expert. I do not trust the dealership to know much either. I have a mechanic who is quite good (but who was stumped by the car's behavior) and I can relay any technical information to him.

    I would deeply appreciate any light anyone out there may shine on this catastrophic problem.

    Thanks,

    Have you modified the car in any way? Any ECU changes/piggyback/reflashes? Are you running any cold air intake? Have you recently done any work on the car, especially withe the air intake system? Have any CELs gone off? If so, what were the codes?

    Dear Mr. Skreekin,

    Thanks for your response.

    The car has not been modified in any way.

    The only work done on the car was the oxygen sensor and catalytic convertor in the past couple of weeks or so. No work done before the car started acting up.

    I will do some research and get back to you with answers to your other questions.

    T

    Do you have a check engine light?

    If possible does your mechanic have a code reader or a scan tool? If your case it could help finding this problem.

    Scan tools new may cost up to $4k.

    Code reader 50 bux, BUT may not be so helpful.

    Without having something like a OBDII scanner or multimeter it could be difficult to really track down over the internet due to us relying on info/data from you to diagnose the problem.
    • How many miles on the car?
    • Last time you changed the fuel filter?
    • Has the fuel pressure been tested?
    • What octane gas are you using?
    • Is the car using coolant?
    • Has the car been tested for a possible blown head gasket?
    • When were the spark plugs last changed?
    • What is the plug type/part #?
    • What is the plug gap?
    • Did they replace the front or rear O2 sensor?
