Hello - I have a 1992 Nissan Hardbody (D21) pickup, 4-CYL, 2.4L Engine (KA24E), manual transmission. Mileage is above 250K MILEs.
Recently, my truck was idling bad and idle was fluctuating from 1600 to ~ 1800 RPM. SPECs state that it should be 750 +- 50 RPM. When I went to adjust the idle during a tune-up, according to the service manual, I could not since the idle screw seemed to be "stuck" and somewhat "stripped".
This was probably done during the last tune-up more than a year ago and that mechanic shop is no longer in business.
Can I "drill" the screw out with a screw extractor? Or--is this screw set so that it will NOT screw out? I hope I can fix this since a new throttle body is quite expensive.
