My ZC has some issues after it rains out. It seems to drive fine the next day after rain for about 5-10 mins then it starts to stumble at low RPM's "1-2500". Kinda sounds like its chocking up. Now like I said this only happends after it rains or if its really humid out. Any idea what the issue could be? I had this issue before my turbo was installed so I doubt that has anything to do with it No codes or anything. Thanks

 

maybe moisture's seeping into the dizzy?

 

Mine has and has always done the exact same thing. I know this is of zero help, but I'm glad you asked.

Mine seems to only be at partial throttle. It seems like its missing or sputtering at about 2000 rpm. Like you mentioned, it only happens when its humid or rained recently. It usually sputters, then surges once it come back to life.

I've noticed that the A/F meter seems to show lean when it does this, then it jumps back to rich when it surges. Strangely enough though, it feels like an ignition miss, not like a fuel issue.

Are you using the 88-89 integra ECU? I am. I can't remember if it did it with the Si ECU..

 

therealZC, thats the exact same issue I have. I am also using a Integra ECU!

 

yes check the cap and rotor.,.... once it rains hard and humidity its around , will make humidity and bad contat on the rotor and cap.. take it out, clean it and see if it goes away...if not then we can keepo thinking
