Hey,

I tried searching for this problem on the forum but couldn't find any info so I'd thought I'd ask you knowledgeable guys. It's a problem during start up when the car is cold. It's been occuring for about 3 months now. Basically what's happening is when I fire it up, the rpms shoot up to 2 grand then fluxuates back down to 1.5 grand and back and forth for about 2-3 minutes. I've already done basic maintenece (fuel filter, o2, spark plugs, wires, dis cap/rotor). I'm not sure what else I can do. Please help!

Thanks,

 

Anyone have any ideas? Please!

 

are you coolant levels alright? if not it could be your fitv or iacv. how is it once it warmed up?

 

I have the EXACT same problem.

After it warms up, it is fine with rough idling b/c i have a code 41 (o2 sensor)..not a problem getting that to work there.

Bump for help for you and me

 

recently ive been having the same problems with my idle and codes 6,7 and 10 but i found out that they all share one of the same wires... i looked at the wire and it was loose.

i fixed that but its still acting up just without engine codes. spraying the entire im(the valves too: iacv,fitv,pcv) with carb cleaner really helped too(also, seafoam= ). i think its my fitv so im going to look at that.

judging by the symptoms you mentioned this could be a helpful link: https://honda-tech.com/zerothread?id=558236

I've had the same problem it bugged the **** out of me. Because after a new fast idle and o2 sensor it still idled up and down. Finally found out that the gasket on the throttle body had worn out and had a vacuum leak. Check for vacuum leaks.
