check for a vacuum leak or if not its your IACV (Idle Air Control Valve) its behind the throttle body...i have a 97 hx with the same motor nd had the same problem

 

GLW Fixing...

 

you have to have a vacuum leak to have your idle that high and surging. spray carb cleaner around the intake manifold and see it the car revs up more or chokes up. then check the spot for a leak.

 

it only does it in 2-3k then when is get to 4k its all good then when its idling it just revs to 1.5 and back down to 1k

 

Did you check this?

 

im going to check that today

ok i put the car on the computer and this it what it showed

manifold absolute pressure or barometric pressure circuit high input p0108

throttle/pedal position senor a circuit low input p0122

intake air temperature sensor circuit high input p0113

evaporative emission system pressure sensor / switch p0450

 

bump

 

Do all of these codes return after resetting the ECU?

 

there was a leak by the manifold but i fixed it but it does the same thing but my car never dies it just does that throught 2-3k rpm and everything is good when it passes 3k or if i shift it at 2k and after i rest the computer the codes just come back agian

 

P0113 - Is the IAT sensor plugged in?

P0450 - Is the gas cap missing or is the cap seal broken? This can also be caused by a vacuum leak.

P0108 & P0122 - Are the MAP sensor and TPS connectors swapped?
