    Stock Engine Detonation, New to SVTs

    I originaly thought that it was the IMRC's, but how random my problem is, combined with the signs of detonation, I highly doubt it. Also the rough idle leads me to believe its my plugs or wires. I checked under my hood at night with a "black out test", and found a few blue jumps or "electric...

    Stock Engine Detonation, New to SVTs

    I'm almost positive now that my high RPM troubles are detonation. I had a 95 5.0 with a Vortech S-trim 10 psi, so i know the sounds of detonation. Here is my problem. On a WOT Run, my stock 98 Cobra recently started to hesitate and "buck" lose major power from 5kRPM and up. The engine would...

    Look good or no? Chameleon

    Its actually the mystic cobra. I went to the San Diego Zoo last weekend, and there is such a thing, and it looks EXACTLY like the mystic paint job! Very cool.

    98 Cobra: Recent Engine troubles

    After a long week of driving (1000+ miles in 8 days) my 98 cobra with 54,000 miles on it picked up a rough idle (feels like a miss), has had a drop in gas mileage, and the last time i got on it, i thought i heard some detonation, and around 5k rpm at WOT it felt as if I hit a wall in...

    Hesitation and bucking while driving

    check fuel filter(s)..? thought there was only one?? but i did change it about a month ago, but right before running a powerful injector cleaner (BK44), maybe kicked up some debris in the bottom of my tank. Anyone think it could be a bad fuel pressure reg? I just looked, and found a broken...

    Hesitation and bucking while driving

    On a cross country drive my stock 5.0, that i had bought a few weeks prior, started to buck and kick while climbing inclines at high speeds. At first, i thought it was the wind, you know how that feels when its head on, and it feels like power on / power off, but come to find out it does that...

    5.0L experts; need help

    On my recent 1000 mile drive, my car flashed a check engine code. At that time i noticed major "missing" or stumbling under acceleration and at constant speed, more noticeable at highway speeds. I used my diagnostic computer and got some emissions codes, which i dont pay too much attention too...

    Spark Plug Wires, blue sparks??

    They are the heli-core. I think im going to order the ford 9mm. They seem to have the least complaints. Taylor wires sound pretty good too. Will checker auto parts take back wires after they have been on my car??
