Heyh, guys. so i have a 1990 ka24e in my 240 and the last week when i start it up it just sputters and revs from 200-1000 rpms. i give it gas past 2k and it sounds fine but when i let off the gas it goes back to sputtering and eventually stalls out. any ideas of why its doing this??

Could be your IACV (Idle Air Control Valve) failing. Have you tried cleaning out the throttle body recently with an intake cleaner?

no i havnt tried that. il try that. only thing is it does it mostly when idleing but i get the occational loss of torque while drivinng and then it will come back quickly.
