has anyone had this problem? I've tried reseting the ecu and swapping gas caps, but after a while the light would come back on...don't know what's going on. if you had the same problem, how did you take care of it?

thanks guys

 

bump

 

I have had code 90 since my auto to manual conversion. I tried replacing the large canister with no luck. Check the helms, there is some detailed troubleshooting involving vaccuum and voltage checks. I just havent got around to it yet. Also, I think I read somthing about it having to fail twice after starting the car and the system purges before it will throw the cel again.

 

thanks...i'll try that
any other suggestions?

 

I just ignored mine and eventually it went away

 

i've been ignorin it for a while now...about 6 mos... and it's still there! The strange thing is it came a couple of days after i put back the stock exhaust setup

 

u got an exhaust leak some where!!!! my boy had the same problem

 

hm...i'll check on that...but it kinda makes sense since it only came after i changed back to the stock exhaust

 

Have this exact same problem with my car. Unfortunately, it can be a number of things but I'll tell you what Rick Case Acura said made it go off on mine.

Bypass Solenoid Valve. Mine went bad somehow. Getting it replaced this week, check that - but ultimately you will need to troubleshoot it. If not, deal with the code, doesn't hurt you one bit.
