Could really use some help

[fixkick]

one other way to see bogging in action?
driving, see feel it bog.

then stomp that gas pedal ! even pump it....
each stomp forces the ECU into ENRICH mode, (the ecu watches you pump the pedal, and detects this fast action and goes very rich)

if the power comes up, then fuel pressure is probably low, or the injector is 1/2 clogged.
try running Chevron Techron fuel injector cleaner in it, I hate, additives, mostly, but this is very good, has benzene in it.
this benzene can clean anything, other brands are just cheap kerosene, or other useless cleaners or worse stoddard solvents (cheapest brands have that)

hope this helps you ,narrow the causes.
as can bad gas cap, see if bogging ends with gas cap removed. (if yes, wrong cap there)
