The rpms went over 2000. could it be the air control sensor
It's called IAC - idle air control valve > Did the RPM'S stay at 2000 or drop back down ? The PCM engine computer controls IAC valve according to engine load . Put it in gear , turn on electrical loads , headlamps , A/C etc... an the RPM raise's up so engine will not stall . More then likely the throttle plate needs to be cleaned , they get gummed up an stick at higher idle . Quick Tip Throttle Cleaning EricTheCarGuy If the IAC valve were gummed up the idle would be low or erratic . On some engines a vacuum leak will cause high idle . Videos on youtube checking for vacuum leaks .
Testimonial: "also where is it located, i have done a search and find nothing for my van."
the rpms stayed up, we turned it off twice before it finally come down to about 900, i noticed while he was driving the rpms would go up till he gave it a lil gas and it would come down again. when i turned the a/c off once home the rpms down very low.
He shows you in the video , yours will be pretty just about the same . The black rubber hose coming from the air filter to the engine ,take that off . On the engine side look inside while someone moves the gas pedal .You'll see the throttle plate move .
pretty much just about the same !
we found a hose off going from the mass air flow pipe, between auto zone and napa they sold us a rubber ring and a valve they said should have been on the end of the hose , on the back side of the motor. i can get my hand to it but not get the rubber ring in. there is a bracket in the way. do you have a diagram we can use to figure out where it goes?
