Loses power after driving . Starts to stutter. does anyone know what it might be ?

Its probely the cars speed limet

check ten fuel pump pressure . could be a faulty pressure regulator . run fault codes to find out fault.

-There are couple things cause to do that:
-Air flow sensor, throttle position sensor.

Good luck

You will have to repost and reword this problem... you say it wont move, but that it loses power while driving. how is it losing power while driving if it wont move?

I got the same probleme here did you fix it??

My 95 Geo did the same thing. It had vibration problems for yrs and my uncles told me it was the harmonic balancer that I should replace it before I messed up my engine. I never did sorry to I should have listened. My car started to putter and stutter until one day it wouldn't couldn't go above 10MPH. I replaced the Catalytic converter and my car wouldn't even go. Took it to a mechanic, the crankshaft pulley was all out of alignment and had messed up the crankshaft rod. It would cost $700 to fix. I didn't have the money so he welded the shaft a little straighter; enough to get the pulley back on but I still have to change it he said that If I kept that pulley on it would continue to mess up. It's been running for about two weeks but It seems to making the noise again. I'm working on getting the pulley and I'll let you know how it goes. I hope that it is the same problem I have that way you know how to fix it.

brake booster check valve leaking.

My was doing the same thing, it was an EGR valve and a misfire on the #2 cylinder which required a new spark plug and a coil pack
t

It could be the air intake temp sensor. Would cause same problems described

Replaced both CO2 Sensors.
