Huge rain last night, i was driving home from work... found out that her idle was horrible .. it stays at 1.1k and bounce 1.6 ~2k up and down...

what happened to my car?
now the car idles at 1k and still do the up and down thing but seems better than last night.

I pulled my CAi out, didn't see any water in pipe or TB but the filter was wet though.

I have a 2k GS

help me please

 

By the way, the car starts fine .. other than idle at 1k and goes up and down... everything seems pretty on track

 

is it an AEM CAI? if so then it should have or you should have got a "bypass valve" with it...this prevents water from getting in to the engine...idle on your teg should be at about 600-700 rpm at idle..the only time it is not is when you first start the car, then they tend to idle at or about 1k - 1.5k for a few minutes.

 

the correct idle should be at 750 +-
and no i don't have a AEM cai i have some no name brand CAI from asia. anyways, what should i do now??

thanks for replying

 

one of my good friends just put a new ls motor in his 94 teg. it is doing the same thing.........we can't figure out what is wrong with it.......i've heard of this before and even then no one could really pin point a problem. sorry i know this helped NONE but hey at least he's in the same boat as you
i'll keep you posted if we come up with anything else

The rough idle should go away.

If you'd really sucked water into your engine (in any quanitity other than some droplets) you'd have heard a loud bang as your engine died, and you'd be picking piston pieces out of your oil pan today.

 

Thanks Mike~ ^^:thumbup:

 

Thanks man..
yeah i think you are right..
i kinda feel that the rough idle is going away and stuff
hopfully by tomorrow after i change the spark plugs.. ( just in case if it got wet or someting)

someone told me to check my spark plugs see if they are wet?
is it nessery?

 

car idles alright now... a bit higher than usual but it's below 900 rpm now ( i have SAFC so i can tell the actual reading )

just change the spark plug and seems dry...
should i change the oil as well ... i just changed it 800 miles ago?
should i just wait till 3 to 4k? i use Sythetic oil in it so .. kinda costily

 

If you have water in the engine at all the best way to check it is to pull the oil dipstick out and see if you the oil looks watery or if you get any rainbow affect like oil on the ground.
