so I've been unsuccessful resolving a problem. ive been having for the last 3 months. Any help here would be greatly appreciated.
currently I have 11 codes:
0572
0121
0606
0123
0602
0501
0230
0382
0122
1492
1693
this has the check engine light on as well
The check engine light has actually been on for a couple of years, but no drivability issues noticed.
the mods that might explain some of the codes are:
1. joker fab intake so no grid heaters (I disconnected the relay activation wires that run the grid heaters.) done in 2017 this did not immediately trigger the check engine light thou.
2. single battery on drivers side
3. I just replaced the APPS with new timbo. my analog volt meter quit working so I did not calibrate the new one.
4. new fass wiring harness I just put on hooks to keyed hot not the fuel pump circuit.
truck is a 2001.5 ho truck with a smarty, redline, and a SO pump.
the truck runs away with itself like the throttle is stuck for about 1.5 seconds and then will only rev to 1500 rpm's but it is 1500 rpm or idle nothing in-between. shut down does not change it but if you continue to drive it will go back to running normal in about 20 min. or if you shut in down the next day in might be fine or resume the same behavior.
to fix I have:
1. replaced timbo apps with new one. same symptoms
2. I sent a computer out of a 99 auto truck to carcomputerexchange to have it flashed to a 01 ho truck. same symptoms except now my cruise isn't working.
tried running an 02 ho truck computer throttle was very sensitive but symptoms were not as bad however I'm not convinced it fixed the problem cause I didn't run it very long, and my oil pressure gauge would not work.
3. new fass wiring harness
4. installed flex-a-lite variable fan controller, and removed the standard built-in relays. my thought was the electric fans I have run for 10 years come on at 100% which is a 28 amp draw (headlight dim quite a bit and have always done so) with the new controller they come on at 60% of 16.8 amps. this did not fix the problem.
5. last night I unplugged the blue and green wires from the redline and test drove it 15 miles so far no stuck throttle but before I did that and the new apps I only had 6 codes now I have 11.
I am very confused and need help trouble shooting.
