No Check Engine Light While Raining??

[EagleTalonTim]

Ever since I put a Japanese Swap in my 2.0 n/t talon, the check engine light stays on. It is practically a stock motor. Only mods are cold air intake, headers, and chopped aircan. The codes all point to the MAF, but I have hooked up 3 other ones that worked on other talons and still get the check engine light. One of the codes was the barometric sensor. (I figured that may help.) The light stays on all the time, but does not affect the way the car runs or performs at all. When it starts raining, I can drive down the road then stop and the car begins to shutter at idle, then the check engine light goes off and it runs the same as if the check engine light was on. Any ideas what may cause this and how to fix it?

I have put 3 other ones on it that did not throw the CEL on the other talons....just mine.

The fun is over now comes the spark chaseing. First thing I would do is strip back the cover by the 6pin plug and make sure the insulation is still on the wires. (My 96 SHO did the same thing and that was the problem)

If that is OK start checking the harness back to the firewall to make sure nothing got pinched in the engine swap.

oh boy. sounds like fun. I will post back when i check it all.

ok, i checked everything and there are no cracks in the wires or anything disconnected. everything looks the way it should. I even checked the computer for loose or broke wires. any other ideas that may cause this?

Have the caps ever ben changed in the ECU? I not they can give you fits.

as far as i know, no they have not been replaced. The car runs just fine...it just has the check engine light on all the time unless it is raining.

any other ideas?
