On my 300ZX, a rev limit of 2400RPM indicated a failure of the mass airflow sensor. That was a Nissan safeguard, and it's probably the same on your 240 - check that out, clean it with electrical contact cleaner, and if the problem doesn't go away, replace it.

Engine idles up to 2500 and after 5 or 7 seconds, goes back down to 1200 rpm 2002 escort SOHC


Clean out the throttle body carefully and replace the auxilliary air idle valve. There is a resetting process for this valve so dont just fit and hope!
Check on Google or forums but i think ...when fitted you turn on ignition but dont start car , then put the accelerator pedal slowly to fully open, hold it for a min then release. start and drive car until warm and the recheck.
If the idle is high then settles it is not an air leak. It is something stuck that then releases which is only throttle flap or idle valve. It is always a goid idea to replace fuel, oil, air filters on normal service intervals.

Engine revs perfect to 2500 RPM then chokes out will not run past that rpm. While driving it will not go over 2000 rpm. I changed the plugs, wires, checked all of the vaccum lines even checked for...


Remove your fuel filter and blow through it. Replace as necessary. It may be necessary to check fuel pressure while in operation to verify a drop in pressure. Warm the engine for about 10 minutes and take for a hard test drive around the block and see if that catalytic converter is glowing red(I know you said you checked it). Replace as necessary. Something is plugged. Let me know what you find.
