I guess I limped my tranny today for the first time. The pisser is that I wasn't even getting after it. Came home from work just long enough to change clothes and when I got back in my truck it wouldn't start, so I unplugged the juice and it started right up. Well, I take off and everything seemed normal, so I am sitting at a stop light and the MIL comes on...son of a...Anyway, light turns green and I go but I can only go about 15mph at 1900 rpm. OnStar pulled the codes for me, P0193 & P0090 which are fuel rail related. They said the vehicle is rendered undriveable and wanted to notify road side assistance to come and get it. I guess my question is did the juice cause the fault or was it some wild coincidence and will it reset itself or do I need to take in to the dealer?

Sounds more like a cut back on power command from the ECM then a TCM limp mode command ....


If I were you I'd make sure none of the pins are pushed back from making good connections at the bale's your plugging and unplugging at ...


The Juice doesen't tamper with Fuel Rail pressure ...


Clear the codes ...
