The other day we had a huge rainstorm. I tried to drive through a deep puddle and as I started through the intersection my car died. I found out that my K&N CAI sat low enough that it sucked a bunch of water into my engine. I pulled all the plugs and cranked it over and blew water out each cylinder, lots of water. I replaced the plugs and started it up. It chugged a little and had a hard time staying running. I kept it idled at 1500 rpm for awhile and took it for a drive. I found out as I would come to a stop and push my clutch in, the rpms would drop drastically and the car would die 95% of the time. If it doesn't die, it drops to 300 rpm and bounces between 300 and 500. Normally my car idles at 800-1000. However, while driving, there doesn't seem to be any indication there is anything wrong. The car performs normally until I come to a stop. Any ideas what else could be wrong? I drive a 93 z28. Also, there are no codes present. Thanks for the help.

compression test. also at least change the oil

Forgot to mention I already did change the oil and filter.

compression test. any ticking? normally when you hydro lock the motor you bend and snap rods.

water on sensors? its not reading thme right? it may not send a code.....
best of luck

A tip from a former Import tuner- Some Companies that make CAI's make what is called a " Dry Filter" or " Reserver Filter" - it goes in the upper portion of the intake tube- On our cars you could put it where the MAF an the K&N FIPK pipe connect..

It allows a secondary form of suction in the event that you suck air into your intake-

Its just a little foam filter..


I cant find a picture, but i know that AEM makes them

Good luck!

You got lucky, I know it sucks, but I have seen an engine throw 3 rods when it sucked up some water. I would check the Sensors like said before. You might have to take off the Intake Manifold and make sure it's clear, just to be sure..

also check for blown fuses

El Seano

Checked all the fuses, no problems. There is also no ticking or knocking. I'm 99% sure there are no bent rods, I think I got really lucky. But I'm still not sure waht is causing the low idle, I'll have to do my compression check. Thanks everyone.

Check your sensors in your intake manifold- Ie - TPS, MAF, and IAC, IAT...
Im sure that IAT and the IAC sucked air into them..

And your MAF could have possibly shorted out...
