What does code 44 mean on Ford F150?

As for code 44 this will be present if you did the scan with the engine not running as this system won’t be working anyway. What have you checked so far? I would like you to unplug the idle air control valve and tell me how it idles.

What are the codes on a 1990 Ford F150?

I cleared the codes, ran the test and it came back with only 2 codes, 21 and 44. The 21 code seems to go with your theory of the temp sensor. I will not be able to get my hands on the scanner for a week so I can’t do the test you asked me to do yet. As soon as I get it I will let you know what it is. helpful?

Why does my 1990 Ford F150 run rough?

This will happen for a few days then run great for a few days. When it is happening the truck still has plenty of power, runs fine during acceleration but dies shortly after I let off gas. When it is running bad it is running VERY rich (that is why its running rough I think) but I can’t figure out why its running rich.
