Default idle surge

ok lately ive noticed that when im at idle the engine surges from about 900 to 1100 rpms and also if i turn the steering wheel at idle it drops down to about 750 rpms and then will go back up to 1000 what could cause this ive recently cleaned the throttle body, replaced the air filter, changed the spark plugs...

Default Re: idle surge

i have a similar issue- went to autozone and they scanned it. i put the part on and it's a little better but still revs high- can't seem to find a happy place to stay at! hopefully someone in here has a better answer. i have a 98 w/ a 2.5. just had the engine rebuilt so it'll be around for a few more years.
