ok, i got a 97 GL with the vulcan and today when i started it up it was idling real hard. i mean ROUGH like it was about to stall. my question is, what could be making this happen? it has about 85,000 miles on it.

any ideas are a help.

Thanks,

Roland

start with the Idle air control. Take it off clean it with throttle body cleaner.

should be located right after the throttle body.

I don't have access to a vulcan so i can't help you in the pics department.

the IAC is on the top rear of the UIM, just past the TB. it has a two wire plug, a canister (solenoid), and a aluminum plate that attaches to the UIM with two bolts.

Does it continue to run rough after startup, like while you are driving?
