I have to tap the peddle coming to a stop to idle down to 700 rpms or it will stay at 1100 rpms, just a light tap gets it down. This is what I did so far, first grounded out the alcl waited a min. unpluged IAC started the car adjusted idle to 400 RPMS in drive at an idle shut car off plugged IAC back in adjusted TPS to 0.54 volts STARTED CAR AND DROVE IT 40 MPH FOR 10 MINUTES no change!! Well after that I took off the IAC cleaned it real good inpsected the throttle body cleaned it ( at this time I took the time to ck the linkage for any hangups or play none ) re-installed the IAC well what a difference in fuel milage but still have the tap the peddle syndrome ( fuel mi went up 4-5 mi per gallon!!!) At this time I went back to the auto parts store bought a new IAC put it in re-set it the same way as before NO CHANGE STILL HAVE THE TAP THE PEDDLE SYNDROME Well the auto parts store let me return the NEW IAC (GOOD PEOPLE) SO I asked if they would do the same with a new TPS and they said yes so I put in the new one set the voltage drove it NO CHANGE what could it be the car runs really great other then that could it be a small vacum leak that I cant detect ? I also replaced the injectors I have perfect fuel pressure if that makes a diffence also everytime I took the throttle body off I would inspect it for any play or hangups there seem to be none the throttle snaps back real strong and hits the screww real hard . it has o be a small vacum leak !!! please if anyone has any insight abou this let me know ( I didnt have this problem before I changed my injectors I went with the bosch 111 flow mached no leaks perfect pressure thanks TED
