Does not accelerate

When I go up a hill it is like I am not even moving when I go down the hill I can get up to speed. and I can maintain speed as long as I do not have to slow down , but as soon as I have to slow down it starts all over again this is for a 2000 Malibu it has aprox. 150000 on it we bought it used and the person that owned it before did not really fix anything properly right now the real issue is the whole not going up hills.

The problem with "does not accelerate" is the catalitic converter is plugged with fuel restricting exhaust flow. it happened to me I thought it was the tranny. We had an after market cat put in and ran like new. Good luck

I would start by checking the transmission fluid, and even would recommend replacing it. Hopefully a new fluid and filter change will do justice to the problem. If you notice a burnt smell or dark brown colored oil on the transmission dipstick then its obviously time for a change. Lets hope that its enough to fix the problem, if not, a new transmission/rebuild may be in the near future for you.

SOURCE: I have a 95 Chevy Silverado that boggs down when

If you have a check engine light then have your local autoparts store do a diagnostics scan. This is a popular vehicle and will probably have parts in stock. There are many parts failures that could cause an issue like this(oxygen sensor, air filter, fuel filter, evap system, ect.) so it is very difficult to determine what it is without seeing the vehicle and doing some tests(cylinder compression check, diagnostic trouble codes, fuel pressure, ect.) If you have no check engine light, make sure the dash bulb works and if it does the problem is probably in your fuel delivery system(fuel filter). Take it to a mechanic and get him to do a road test and diagnostics. It will be worth your money.

SOURCE: why is my 2001 malibu sometimes hesitant when

The problem you describe can be caused by many areas of the car. First places to check would be clogged fuel injector, clogged fuel filter or even a dirty air cleaner filter.

When cruse is set, why does it not hold going down hill


Cruise control only maintains speed by utilizing the accelerator. To speed up it increases it and during slowing is removes it. The cruise control will not apply brakes in the event of a steep downhill run. In this case the vehicle will start to accelerate in the same manner as if the cruise control was not engaged. But in theses cases, most cruise controls, once the speed exceeds a certain amount above the set speed, will auto-disengage as a safety feature.

Why does my 2003 pontiac grand prix maintain speed on flat surface when cruise is not turned on?


Sounds dangerous and hard on breaks. I\'d catty with the throstle linkage under the hood. It should twist open with a bit of pressure, than snap shut when you let go. Yours won\'t. The return spring is worn, stretched out, or most likely gone missing or fell out. Find it and hook it up. Or any spring with the power to pull it back to a closed position. Must be hard to restart the car after it\'s warmed up too.

It sounds like you may have a bad bearing on the inside CV half what that is on the drivers side. It is basically a carrier bearing that bolts to the back of the motor that the cv able slides into. Jack up the car and grab the cv axle beside that ceasing and try to move it up and down. Very much play at all and you wind up with that thumping especially under acceleration.

Transmission surge at cruise


check the rpm and road speed when this happens . The cruise control will increase to keep RPM constant but as the road speed drops the auto may be shifting down and as the rpm increase it shifts back before the rpm adjusts. You can override a cruise control in this situation by simply pressing down on the accelerator to maintain the power setting and road speed and when the situation is passed and you take your foot of the accelerator the cruise control will return the system to the set position without you needing to do anything
