Very high rpm @ idle speed Astro 1997
Y'day I drove my van about 10 Kms parked in a lot, after 2 hrs start it again, the engine roared like running @ almost 5000 rpm, got scred did not put in drive shut it off, checked all throttle cables, openedthe linkage between body and accelerator, sent to a local mechanic, checked all codes no problem seen yet.
Can some one suggest the cause.
Noticed for last few deays when I put the car in drive the rpm used to go slightly 20 5 high then roll back to normal after a minute or so.
Pl. advice any problems before I spent too much money on this old horse.

idle air control valve
Did open this finally, was very dirty, checked with turning switch ON, it did move slowly back & front, not rapidly, cleaned with break cleaner , put it back , try to run the engine again, same high rpm, scred to put on drive.
Do we take it to dealer now, does not show any Codes on OBD either.
Should I replace this part cost about $132 Plus Tax, Do not mind as long it fix the problem
Let me know

idler pulleys' bad mon
Most likely ur idler pulley / tensionor bearing / wheel is bad or rusty which slows down the pulley set so the engine has to idle higher to keep up thus get the faulty bearing moving..... again
