The girls Jeep has had some issues staying running for a while but I just haven't had a lot of time to investigate. The past few times it's happened, I've usually just gone out and messed around with battery connections and the problem goes away, but I'm not sure if that's coincidence.
Usually starts and runs fine, but low idle and stalls. Drives fine as long as you manually keep the RPM's up.
Throw 4 codes simultaneously every time the problem shows up:
* P1294
* P0122
* P1694
* P1391
I know what all these mean individually, but I'm confident they're not separate issues. If I clear the codes when the Jeep is running normally, they all stay gone until the next time it starts lowing idle speed and stalling, and they all get thrown at the same time, every time. I strongly suspect they're all using the same 5V power source and that source is getting weak, but I've got my Jeep in the garage right now while I stretch out the rear wells, so I just don't have the time to trace and probe every wire.
Who's got the answer for all these codes being thrown simultaneously?
(P.S.) The Jeep itself is a 2001 auto. The long block however came out of my 98XJ which was always rock solid (swapped because her 0331 head was cracked). Put the 01 intake, cam position sensor, coil rail, on the 98 long block, and using the 01 ECU. Worked fine when first installed, has worked fine many times since. The issue is entirely intermittent, but seems to be occurring more frequently. I won't be at all surprised when this turns out to be a bad ground.
