95 jimmy odd performance

after driving about 30 miles and getting off xway truck seemed to want to stall but didnt. anyway started running strange ,wouldnt shift properly, shaky,hard to keep running so eased my way home doing 60mph .read codes and got po325 knock sensor, po137 o2 low volts, po107 low map, and po122 tps low input. found loose neg cable and removed to clean and retighten. all codes gone except tps code. bought a new one and on way home all went back to normal so didnt install new tps. started truck this am and runs smooth. well shall be driving same route today but with new tps and tools in tow in case problem happens again. any other possibilities as to what caused this. will let you know out come this afternoon as to if get same condition.

those vehicles are really bad for carbon to get stuck in the egr valve and keep it open and cause a large vacume leak.. which would explain alot ofthose codes and would not want to idle..and have horid performance and brakes would be a lot harder to push down.. not really a causein ur case but worth a shot to look at anyway in the future..

i was thinking the egr also. well did same trip and alls normal, think like you suggested egr valve had alittle carbon and it must have passed. thanks k
