    Re: Z3 Loss of power

    I removed, cleaned and silicon sprayed each of the boots (both sides). I am still having the same problems. Thanks though.

    Have you cleaned the MAF sensor? Need a spray

    can of no residue contact cleaner. MAF is easy to get at after airfilter. Need the little spray hose to get between the flow grill. All it takes is the tiniest bit of crapolla on the element, and symptoms similar to what you describe occur. I assume you've also put in a bottle or two of Techron injector cleaner.

    Re: Checked the Valve and Vacuum line

    This should be a "tight" seal IIRC??....vac comes from manifold, solenoid actuates the vac signal to the SAI valve/Kombi.

    do you have a vac guage? maybe tee it in to the vac lines (at the FPR for example) and see what it's reading at idle...should be ~20 in. HG (generic/typical number).

    Re: Update

    Where was the last place you filled the car with gas.
    Was it other than where you normally go.

    same issue

    cut the cat out and it runs great. Had cut the muffler off years ago and recently noticed that the exhaust note changed. (quiet) cars had a check engine light since we owned it. But we cut the cat out and cleaned maf and throttle body.
