Idling issues
Hello, I’m having idling it is on my 1986 302 EFI Ford truck. symptoms:
On start up from cold it idles high at up to 2000 RPMs. After one minute it drops to about 1200 or so RPMs.
When I put it in gear the RPMs surge and it moves vehicle forward without giving it any gas.
Driving around it idles somewhat normal but still high.
When I put it in park the RPM surge again. High RPMs in park.
I have thoroughly cleaned the IAC and IAC solenoid plunger. I have thoroughly cleaned out the throttlebody. I have replaced the TPS.
Can you please give me some troubleshooting steps to continue trying to identify this problem? Thank you
