Recently I drove the car home (15 minute drive). At first the idle and oil pressure were fine but after driving for a little bit at stops the cars idle would drop abs almost shut off. Today I took it for a small drive to test it out and once again was fine when cold and then oil pressure and rpm’s would drop when stopped or in neutral. Any suggestions on what it could be would be greatly appreciated. Thank you

Oil pressure will drop due to pump not spinning when the idle drops.

Perhaps you'd need to raise the idle mechanically with adjustment screw, as thermowax is closing the throttle bit too early.

Fellow member who's FC expert will perhaps chime in, best of luck

 

Thank you I’ll try this and get back
