What's wrong with my 7m?

[guest0720]

The motor basically bogs very bad whenever i smash on the acceleration. It will go if im soft on the throttle and it does reach full boost as well which is 10. I have checked the tps and the other stuff people have said to bog the motor but everything checked out fine. Timing was also done at a toyota dealership. any input would be great thanks.

Mods includes:
Turbonetics Godzilla bov
3" hardpipe accordian hose
hardpipe ic piping
walboro fuel pump
aeromotive fpr
3" exhaust after stock turbo elbow

does it feel like the timing is off when it bogs down. or like someone pulled a hose off in the middle of your run and put it back on when you get off of the gas.

could be a boost leak-> fuel cutt.

i know for sure there are no leaks. the car drives fine as long as im easy on the pedal.

sounds like my 6m when the fuel pump was just starting to go out... it acted real funky like that, maybe a fuel filter or something also ? No promises though. 7m's are funky...

My 90t was doing the same thing, it turned out to be the ignition timing. Just because toyota set the timing doesnt mean it was done right, re-check it.

i basically have a new fuel system so that cant be it. but ill see about the timing. thanks guys

Sounds like the fuel pump. Was it repaired or replaced? Have it checked. Could also be the fuel injectors or even spark plugs/wires maybe the distributer?. When's the last time you had her tuned up?

 

[guest0720]

the motor is a rebuilt and the fuel pump is new, so ill check on the cps spark plugs and injectors thanks.
