A list of problems
I have a 92 f150 4.9l auto. Recently I have been encountering some weird problems. First is I all my lights flicker when the truck is running. My voltage gauge is all over the place but my digital gauge is pretty steady. Ive checked grounds and all seem fine. Second my cruise control stopped working. I have checked all fuse, horn works, and my brake lights work. I checked for codes and got 121,628, and 634. I replaced the TPS for the third time in a year cleared the codes then checked them again and got 111. I then tried to do a koer test and this brings us to my last problem, when it was time for the dynamic test the rpm stayed over 2k and didnt come down until I turned of the truck. I did another koeo test and get 121 still and after driving around the block i get 121, 628 and 634 again but no 111.The truck rides fine no major problems but i can definitely tell something is off.
I have also checked for vacuum leaks, My mlps I changed about a year ago. So I have no idea where to start on any of this.
