Thread: IACV Highport? Lowport?

For some reason I'm having timing issues. Right now my crank timing is set at 18 degrees and for some reason it still feels sluggish with the A/C on shifting from gear to gear and wants to stall when I break and press the clutch in. And I solved this issue before when I changed out the IACV.

My question is...

Are the highport and lowport IACV interchangeable?

yes

Yup, I've been running my lowport one on the high port for a while .

Have you replaced your MAF? What's the voltage at idle?

You ruled out FICD already? I'd say it shouldn't stall on the A/C without it and warmed engine.
