Hey guys, first post on this site. The search button is awesome and has kept my truck running for the past year except for the problem I have now. 1993 f150 5.0 2wd just hit 200,000miles yesterday! Long story short kind of... started it up last week and it sounded like it wanted to die gasping for air reving high then low. "Limped" it around back to the garage with no check engine light on but scaned for codes anyway and got all kinds of codes. Disconnected the battery for awhile and scaned again KOEO and got 121,122,123 all TPS, 111 IAT, 10 camshaft position sensor. KOER 122 TPS and 998 shift solenoid. so I changed out the IAT and the TPS. Drove it and ran good with no codes popping up one day but the next they all come back and shifts hard in first and second. A few days later after it happening intermintelly I scan for codes and get KOEO 122 and 10 KOER 122 and 998. Well friday had my reserve weekend 4hr away and had no choicebut to drive the truck. Check engine light on running good execpt for hard shifting in first and second. Pull over after 3hr of driving and getting back on the highway behind me is a big freakin smoke screen, pull over and im leaking transmission oil. couldnt see where the leak was coming from so i put in 3qts. and limp it back home. I need help guys!!!!!! My TPS is on the bottom of the throttle body so I dont think its adjustable, am I wrong about that? bad computer? any ideas?

 

start with finding the leak, look at this link from a post i made about engine codes for obd 1, https://www.f150forum.com/f10/list-c...chicles-73387/ ,
i dont believe there is a 10 code, rerun your codes, count very carefully... then use that link to check them, if they do end up being 3 digit use this website i found > http://www.freeautomechanic.com/diag...blecodes7.html good luck!
