I feel a very slight shudder when idling after the engine warms up. I had it die once while idling after a week of sitting and show check gas cap on the little electronic screen.
Long term fuel trim bank one is 3.9%
LTFT bank 2 is 0.8 %
STFT bank 1 is between -1.6 to +5.5
STFT bank 2 is 0.8 solid.
measurements as I sit idling for about 15 mins. Is this normal for fuel trim for this old of an engine? The only codes relate to instrument cluster and abs. At least that’s what my BlueDriver tells me. They are b2900,c1805 u1262, u1041 I would be happy to hear suggestions about these codes too. I am planning to tow with this truck and especially want the breaks to work good. Thanks!
Well for that age you're never going to get perfection but the one side is running better than the other. So the side that's running bad probably has something like an intake manifold vacuum leak or a problem in the fuel injectors on that side but most people they're going to live with it with an old thing like that rather than start tearing the engine apart
