Default rain and idle problems!!!!

Ok, Here are the specs of my car. I have a 2000 impreza rs 2.5, it has headers, which was just installed, cat back exhaust, gravel sports intake, and torque chip 2 piggy back. Here is my problem. For some reason when it rains out some what hard, the car idles ruff. The top mount cold air intake has the scoop plate cut to a certian level to allow air to flow through but keep the water out. that is only installed when it rains out. Say the car is sitting running and its raining hard out, the car will run fine and than start to idle ruff, i pulled the car into the garage and opened the hood, and the intake does not seem to have any water on the filter. but if i look at the front of the engine bay, at the passenger head light area, there is water laying in the bay. has anyone had idle problems with there car when it rains? can someone give me some pointers to look for and maybe check? thanks

Sounds very symptomatic of bad spark plug wires.

Wich subarus are known for. What happens is when they get wet or there is alot of moisture in the air the wires start arcing to each other or to a ground via tiny cracks in the wires insulation.

wires would be a good place to start in my opinion.

Also, in my experience even just taking them off to change plugs, as you have done, will cause them to fail prematurally, in theory they should last about 60k.

I havent seen many subaru wires last that long though.

Sounds like the same way my 99 RS ran when the wires were shot. It shuddered like crazy when it was raining or really damp out. Wires fixed the problem for me. OEM wires aren't all that expensive so I'd give replacing the wires a shot. Worst case is you won't need to do them for a bit longer down the road.

However, the ignition system is designed around those wires and the ridiulous amount of resistence in them.
