Hey all,
I am having problems with stalling out when putting it reverse and sometimes drive while the rpm’s are above 1k at idle. Mainly when it’s cold. When it’s slightly warmer up the rpm’s will drop and the engine will catch itself. Reverse does engage kinda harsh too. I replaced the Transmisson because the factory one broke two bands. Since then I have clean MAF sensor, replaced intake manifold gaskets, and added a cold air intake. I did reset the fuel trims when I replaced the manifold gaskets as the old ones were found leaking at my job. They are sitting at -10 for long term bank 1 and -2 to -3 for long term bank 2. Anyone have any suggestions? Vacuum leak, Misalignment on the PRND sensors, etc?
Thanks all,
Gavin
