G'day I have a my00 WRX, yesterday was driving home when it it bucketed down with rain, pulled up to the lights then my car started to jerk about then as it would idle engine would cutout left it for about 20mins or so then it worked fine, it kept jerking till I got home round about every 3000rpm in any gear does any one have ideas what's going on?

Something got wet

rain or no rain.. doesnt sound electrical as i first thought.

could really be a series of things.

based off experience, check your boost/vaccum line going into your manifold see if its cracked or off.
possibly air flow metre,
throttle body issues,
intake manifold gasket leak...

check those mate...might not be the answer but will help diagnose the issue

Thanks ewrxion87 will look into it

Do you have a CAI tht runs down through your guard? If so the filters probably for wet from your front tyre or just splash up. If its running fine at the end of today, providing you dont drive through any small creeks, I wouldn't worry about it too much

Thank god it's running fine, is there anyway to prevent this problem, other than not getting wet ha ha

It's a GC8 right? What cai do you have? If its not an underbody one you'll probably find it came in through the vents on your bonnet of they're not covered under them

Could have a cracked lead or coil casing or a casing on a connector, with the motor running run a hose gently over all the different electrical connectors giving them a wiggle and time to get wet to see if it repeats itself, then replace or seal it with silicone after you've dried it.

Got a pod filter and no cover under the bonnet vents?
