Hey there all, so like i said my engine idles at around 2000rpm, i say around because sometimes it drops to 1500, and other times it idles as high as 3000,

Im really a noob when it comes to Fuel Injected engines, any help would be Greatly appreciated.

Welcome to the BBS.

Can you provide us some more information, what year and model Legacy do you have, turbo/non-turbo, manual trans/auto trans, how long has the idle been like this, what maintenance has been done recently or to try and fix the problem, and is the check engine light on?

Certainly, Its a 1994 Sport Sedan, it has a TD04 and a FMIC, awhaile ago i took my car to the shop because the ABS light came on, well the subie techs told me i needed a new water pump etc, so i got that replaced. before i took it into the shop it idled below 1000rpm, then after i got it back it idles around 2000rpm. No CEL's or anything, it runs well, just high.

Did you tell the shop that the idle isn't right? They did "something" that affected the idle. Did they suggest replacing the timing belt? It has to be removed in order to get at the water pump, so depending on your mileage and when it was last done, it's typically a good idea to replace the timing belt at the same time.

So did they address the ABS light that was on, or just the water pump?

If all that the techs did was replace the water pump, which requires pulling the timing belt, I'd be suspicious if they didn't get the timing belt aligned correctly, which caused it to have a poor idle....and to "fix" it, they just raised the idle. This is purely speculative on my part, but without knowing what they told you or suggested to be replaced, I've formed an opinion about the shop.

You could look at the throttle stop screws and the idle air control valve to see if the white paint across the throttle stop screws and screws on the idle air control valve has been scratched away or if the marks have moved.

What area do you live in?

Denver, Colorado. Im almost Positive they replaced the timing belt, The Mechanic i got seemed capable, and when they checked the ABS light they came up with nothing i guess, so im assuming the code fixed itself?

IF you can't seem to find the problem troubleshooting through here take your car to Greg at slodrive in longmont. He can fix your idle and tell you what other shop may have done wrong at a very reasonable price

Will do, thanks.
