Engine check light now comes on from time to time. Code 24. Air control valve or circuit.

Have tried a couple of AFM's now and seems to be the same, although the boost loss issue is less obvious.

So in need on an IACV to eliminate this option. JWS to the rescue.

Update. Now running with the new AFM and second hand IACV, ECU has been reset, and still throws a check engine light on code 24 after a while. Seems to drive fine though although there is still a sligt hestitation when cold and cruising. Feels like a sort of surging. Boost levels were checked with Doug and all looked OK.

Pod filter was removed a week ago and replaced with the stock box and panel filter.

Next?

when does it throw it up Bob? before/after/during boost?

Just so I can find it easier next time.

Check light is pretty random. Still haven't solved it.

I had the same problem, error code 24.

I did the following and it fixed my problem, installed a new cluster + neutral position switch. Pretty cheap and you do it yourself
