SignUp Now!I may have ommited some other readings at the time. Of curiousity, while idling I removed the vacuum line off of the canister line before the check valve, and with it uncovered the idle increased slightly, but i registered no changes to the above readings.
Look at the ds and see where all of the blm cells are at. If you're pretty universally high in all cells then you should turn up the fuel pressure. If your idle cell is the only on that's high then I would still suspect some sort of vacuum/exhaust leak. I like to see around .44 on the tps at idle and also, what are your IAC counts?
EDIT
Make sure you're in closed loop because even if the idle changes if you're open loop the ecm isn't going to make any adjustments.
thanks for that helpful info. I will reset the ECM as you have advised and report back.If you are running a TT chip I would suggest resetting the ECM (orange wire by the battery with the black plug) and then starting the car on first key-on then letting it warm up to operating temp. Then shutdown the the car, start it back up again and check the numbers once more. Maybe your car has learned that idle BLM from a previous issue and now it just needs to correct itself. Thing about TT chips is they only run a closed loop idle the first time you turn the key-on/start it. After that they run open loop idle for smoothness based on what it learned the first time you started it.

My 87 GN has started making an abnormal whistling sound when slightly opening the throttle.
It seems to have affected drivability somewhat with a little hesitation off idle.
Intake leak? vacuum leak?
Any thoughts?
thanks
