MAZDA MIATA RPM PROBLEM

1990 Mazda Miata • 201,000 miles

I have a 1990 mazda miata it runs but idle is very low like 250 rpms and it wont move unless u have rpms at 4000 or it wonts to shut off I changed mafs and checked timing ive checked the ecu and the injectors I dont have any clues of what else it could be and I have no check engine light on so im thinking something mechanical.

Clean the throttle body and IAC and retest.
