shuiyuan · 12-07-2004, 07:38 AM

i bought a 1991 supra non turbo auto, but its very slow, slow than my old 240sx, and when the can run at 40-50mph i will step the gas, but the speed only raise a litte bit, can you guys tell me is some part broke cause this problem? 200hp should slow than 240sx right?

i think your pedals arent as sensitive as they should be. when my mom got her transmission fixed they tightned the pedals and now our honda oddessy accelerates and brakes much faster.

hi
is your box kicking down cos if it aint a good moped should pass you . :blink:
try manual shifting to hold the revs +see if any change + let us know.
Also check for missfire or poor running under load you can be losing a whole bunch of horses ,often worse in an auto !

the 7mge engine is a good engine and can perform well
does anything else happen when you try and step on the gas.. any smoke... stuttering things like that?
manual or auto?
