Misses high RPM hesitations... Never thought it could happen to me!
I Never thought it could happen to me!
I suffer from heavy missing at low rpm during the cold start routine and after warm I have misses 1 every 10seconds or so, I figure this is normal
But lately I have been getting misses at 3000 RPM and hesitations around 6k or so, usually when VDI doesn't work, but before when VDI didn't work I wouldn't get the hesitation. The car actually bucks during the hesitation.
I have always had oil pressure that stays between 30psi and 60psi never over and never under. It is a fresh rebuild around 10k ago, full mazda reman. I have installed a cone filter, TII fuelpump, and S-AFC. S-AFC is tuned to -2 2000rpm, -3 3000, -4 3500, -4 4000, -3 4500 -1 5000 in the low thr and +6 5000, +5 6000-8000 high thr.
The fuel pump is no more than a week in the car, but after I installed it i had no such problems as I am encountering now. I even lowered the %'s of the low thr by another 1%. What should I do, lean it out more? Could I be getting to much fuel? Plugs were not fouled when I pulled on out yesterday.
