1.6l running badly!

Hey guys, a friend of mine has a 97 impreza 1.6l gl but the "check engine" light has come on lately and I noticed that its ticking over very high, about 2,000 revs, he brought it to a garage to get plugged in and they said it seems to be losing air maybe in one of the vacuum pipes? does this sound right? I checked all the pipes and they seem fine, another thing i noticed was that the accelerater sticks alot so I took off the injector and cleaned it out..no good tho, now im thinkin could it be one of those modules on the injector maybe? has anyone ever heard of the 1.6 given this kind of trouble? any advice would be greatly appreciated!
Cheers!

Sounds right about losing air could be a small hose with a tiny cut in it also it might be the idle air conrtol valve thats why it could be throwing up an engine light.................. and with the sticky accelerater i would get my head under the drivers side footwell and grease the accelerater cable and mechanism and then spray a small amount of wd40 to the flap on the trottle body where the accelertor cable meets where it opens and shuts the trottle that should do it it wipe any excess wd40 sorted my problem awhile back...................

Re: 1.6l running badly!

Cheers for the advice, im fairly certain all the small hoses are fine and I just cleaned out the trottle body again, is the IACV the one sitting on top of the trottle body? I took it off anyway to have a look and theres a kinda pinion spring inside,cleaned that out 2 but the car is running worse now..whoops! just want to know if that is the piece before i go replacing it?
Thanks again mate!

Re: 1.6l running badly!

you could do a dianostic test and it might throw up the ''iacv'' as the problem its the 1.6 you have isnt it id imagine you can read these codes manually cause it a classic but not to sure..............
