    So i've had a slight slight ping for about 6 months, really faint. in the past 2 weeks the pinging has gotten louder, but still only at about 10% throttle and in the 1000-1400 rpm range. Then a few days ago it threw the 71 CEI code, which is malfunction egr. I knew i had a small crack in the...

    hours of work and nothing, seafoam = crap, new ngk plugs

    It sounds like metalic roughness of the motor at 1200-1500 rpm only under light throttle. Yeah i wouldnt think it would ping at that low an rpm and still pull hard and smooth to redline. Its almost a clacking sound. I had a buddy who knows more than I about engines and has turbod his car he...

    pic of TPS, but which one to adjust, looks like two

    Ive read through lexls.com tutorials many a time, on the guide to adjusting the tps i see only one sensor on the front of the throttle body, i'm pretty sure that the sensor closer the to the manifold is the tps but can you guys clarify what the other is? looks the same, has the same adjustable...

    I dont think it is leaking, but i'll check the fluid level today at lunch time. But when the wheel is turned about 30-40 degrees either way it will make a small moaning sound like a beached whale, its not loud but its noticable.
