SOURCE: low power can't accelerate ch engine light jus came on hour ago

Hello;
You need to have the codes pulled and diagnoised. It could be the cam sensor, fuel pump, fuel filter, or the catalytic convertor as well as a combination. Have you cleaned your Mass air sensor?
Hope this helps;

SOURCE: Acceleration

Is the check enigne light on?

If not then it could be a trans issue. Check the fluid again to make sure it is level. put the truck on level ground and with it running and in park check the fluid. Add fluid if needed to bring to level. Then test drive. If it still does the same check the fluid level after driving to see if it REALLY hot. If so it could be a sign the tranmission is failing.

Onyl other thing i can think of have you replaced the tranmission filter? if it was really clogged up it may, long shot, cause what you are saying as well.

SOURCE: What does reduced engine power light mean

this model has what they call fly by wire.. no accelerator cable. If the computer detects a problem in the thottle system it will not allow the engine to accelerate and will show reduced power and possibly set a check engine light. The dealer usually wants to replace the throttle assembly which is very expensive and usually un nessesary.
I have had a lot of succes with just cleaning the throttle plates real good.

92 buick lesabre 97000 miles, on slow acceleration, @ 40mph going into 4th gear there is a mild chutter, same @ 50mph going into OD mild chutter and when down shifting from OD to 4th. All is when slow...


This sounds like a vacuum leak prob. At low acceleration there isn't quite enough vacuum for smooth shift.. But romp on it and it creates a vacuum at the same rate as your gas is getting sucked.

best advice is dont go 40mph in 5th gear... if you are going up a hill at 40mph in 5th gear i have no doubt that it is jerking, your putting too much stress on the engine. shift up to 4th or 3rd you will be fine. 5th gear is an overdrive gear. 55+mph

I have a 1997 landcruiser,when driveing at 40 to 50mph a vibration appers when accelerating up to 70mph it gets worse take foot of accelerater goin down hill thers is no noise or vibration


Check your universal joints in the drive shaft. When you remove your foot fromt the accelerator you are no longer applying power to the rear wheels and in turn there is no load on the drive shaft. When you accelerate below 40mph, there isn't enough centrifugal force to cause the driveshaft to wobble, but once you go above 40mph, it begins to show slop.

Another thing to check is your wheel bearings.
