so my 89t is running shitty and missing, when its hot, the miss goes away periodically then comes back, i disconnected the afm connector and the idle didnt change, but when i revved it it stopped at 2000 or so rpm, which i think is normal, when it was cold i did the same thing and when i plugged the connector back in, the engine almost stalled, disconnected it and it ran fine, im getting an intake air sensor code before i did that, and after i had the afm code and that one cause i unplugged it, so is this normal for the afm to act this way? im about to give up on this piece and have someone else look at it, im running out of ideas.....
