  • Weird idling symptoms

    My 86 1D, Most times I start the car up she will idle up to about 1800-2000rpms. If I shut the car off and start it back up it idles normal with no issues at all.

    After the car is warmed up if I shut it down and soon after start the car she will idle too low and stall unless I feather the gas pedal. After a minute or two of driving the idle relearns itseld and idles fine.

    I have installed a brand new TPS sensor with new pigtail. I have also installed a brand new IAC. When I first installed all this everything was perfect but has since evolved into the above symptoms.

    This car is not driven much and prob less than 600 miles a year (maybe less than 300 to be honest)

    Anyway, any input would be appreciated.

    I am alsomost thinking the Computer or maybe O2 sensor...??? I have no idea
