I have a 1991 Legacy with code 24 and it would not fire on cylinder one as per the usual in limp mode with said code.

I replaced the tps and now it fires on all 4 and it's a new pre-calibrated IACV. Is it possible calibration is off? All the wires have been rebuilt/replaced that got to the iacv. I put in a new ecu and it runs a tad smoother now at least. 

 

Symptoms:

-Cold engine must be revved to about 1.5 to 2k for a few seconds so it's a tiny bit warm to run decently enough. Warm engine is fine.

-Idle is higher than it usually is.

-Automatic Tranny; Shifts to soon and makes it bog and struggle to speed up

-Overdrive engages and stays engaged until under 40 mph which it never did before.

[Symptoms are the same across both ecu's except the old onw just made the idle a tad rougher.]

Sounds like the new TPS needs to be adjusted.

Cold running issue could also be coolant temp sensor. Doesn't always throw a code.

I had it in a shop for the tps. They calibrated it for me.

Thermometer and coolant temp are all working properly. And were recently replaced since they're a common problem for the car in the first place.
