Hi. When I start my car it idles rough at 4-500 rpm. I spayed brake cleaner in intake and revs went up

Hard to start then only runs at 500rpm. Not missing and most sensors are new from rebuild. The engine is worked and fuel system is aftermarket. Regulator is original.

Do you have a check engine light?

No references on this vehicle Mit1/Database-try cleaning out the idle air control valve and see what happens

Have it scanned for codes and check for vacuum leaks. Verify fuel pressure when the problem occurs.

Most proberbly will be crank angle sensor, they will not set a check light and you will have spark but no injector pulse.
