Did a tranny swap last week both aw4 transmissions so it was a direct fit back in everything hooked up fluid levels are good but when I went to drive it it would idle fine how it did before around 6-700 but when I try to accelerate nomatter what gear I’m in it stops at 1000 rpm stutters and backfires like crazy giving me no power. I’ve checked the fuses , replaced the TPS and MAP sensors and still same issue I have fuel pressure not exactly sure what pressure since I don’t have a guage but it definitely sprays if I push the valve. Does anyone have any ideas ? I’m at a loss.
