At idle my long term fuel trims will climb till they reach 17~ but when I drive and I'm at 2.5-3.5 rpm the longterm drop to 0-5 and the short terms jump to 25. Under heavy load 3.5+, like when passing on the freeway the short terms drop back down and the long term jumps up to 15-17.
Really crap acceleration as well.
I just replaced the fuel pump in the last couple months and the problem has persisted.
Also replaced the fuel filter about 6 months ago.
Could a faulty FPR be leading to inadequate fuel? I also have fuel pressure bleed down to 0 when doing a key on pressure test.
