Stumble and P 0251???
 

I just got home from driving all night and one the way home I had the cruse set and I THOUGHT I heard the motor start to sound a lil differant and right then I noticed the cel light came on. Then the truck more or less stalled but immediately recovered and the cruse never came off. It kinda sounded to me like the injectors might have had a little more rattle than usual but it could have just been me bein paranoid. but I drove another 150 miles or so and no issues. Once I got home I checked and cleared my 2 DTCs and I had a P 0251 and a P0602, but the 0602 is just from the smarty.

My FP was fine, 15-20 lbs depending on how hard the truck was pullin and my RP was fine too. And after doin some research it seems it may be my FCA but my truck has a little less then 54k on it and I put a new FCA on 20k miles ago or less.

I know that even though my FCA is relatively new that it could still be the problem but what do you all think?

Should I start with the FCA or look somewhere else, or drive it and see what happens, or ???

Thanks for any advice.

I would just double check all the TST connections. More times than not, that is the issue.

Thanks for the advice, I will check on that, for some reason I am kinda thinkin TST but I have no evidence, just a feelin.

Anybody else?
