Poor Performance Please Help Ok here is the question. I recently completed a Hooker Super Comp Ceramic LT & ORY install. It went pretty good Changed the plugs & Wires while i was there. Runs great unless it it raining heavly. When there is alot of rain or water on the road during normal acceleration, the car feels as if it running on 4`6 cylinders. If you romp down on it it clears out for a while. Very annoying has anyone ever experienced this problem? If so what was the problem?
Any and all help would be greatly appreciated.

No I havent got a professional tune yet. I just done the hand held route. I already had it before the LT install. But the problem only arises after alot of rain or when there is alot of rain is on the road. Ran good for a month or so. It may be the tune but i dont think so, i would think if it was the tune it would do it all of the time, and also it should of done it as soon as soon as the installatio was completed.

Heres what u do.Take a water hose and try to track it.Check the rubber seal in the hood by the pcm.Look at the crank shaft sensor.Look at the knock sensors which are doubtful but could be a possibility of getting wet and pulling timing.Check the air dam and your filter possibly pulling water into the intake.

Also ck the harness that runs from the pcm down the passenger side inner fender for the starter, crank sensor, etc. it runs close to the header and the heat wrap on it is questionable, it may have burnt through to the wiring. I had this problem with my car.

Yeah I had the same problem but all that does is blow the fuse for the mass air and 02 sensors as they are on the same fuse.Im not trying to be a smartass or anything so please dont take me the wrong way.He was saying it only happens when it rains or there is water on the road.

mine only did it in the rain and it was more than an inch away form the headers when i took the passenger header back off the wire insulation was all gone and never it blew a single fuse.

Get out there tonight after football and start the car in a nice dark place - chances are you will see some arcing, if not use a spray bottle and wet the area down gradually if you get no results up top - suspect your 02 sensor wiring.
