car runs good but after driving a while it looses power like it isn't getting gas. It does not die but it won't excellerate.










I guess I should have read the bottom of the web page. Sorry I bothered you.

Check your fuel pressure and comeback with the readings this is where we start without it I cannot get to the other areas I need to rule out the fuel system to continue to assist.

Possible problems: Exhaust restriction and fuel pressure, MAF/MAP/TPS sensors
