I have a 98 mazda 626 4cyl with a 2002 motor in it. It cranks and run fine in idle. But when you press the gas pedal and it reaches 2000rpms it blogs down and shakes. Will not go over 40mph.

Question type: Maintenance & Repair

I've change mas, iac, fuel pump and fuel
filter, injector rail and injectors, throttle
body, egr, fuel regulator, coil pack, wires
and plugs. Checked timing and
compression on all cyl is good, catalytic
converter and muffler,  computer and fuses
and I still have the same issue. Dont have a
clue asto what could be left to do. Its takes
driving a mile to get up to 40mph. Oh yea
and I checked fuel pressure which was
good. Any help would be appreciated.
