Car is not wanting to accelerate

Way I see it is that you may have a problem with the fuel delivery system or that perhaps the advance is not working properly when you accelerate. The latter is computerized so you might have to use a dealer or someone with special diagnostic equipment.

When I see that code and those symptoms I typically start by looking at the timing belt. When the timing belt gets stretched it will cause this code to come up. The other cause could be a bad Crank of Cam position sensor but we need to eliminate the timing belt as the problem first. To check if the timing belt is the problem do a compression check on the motor to see if you have 0 compression on any cylinders. Once you have done that let me know the results and we will proceed to the next series of checks.

Engine off, key turned to run position, and press accelerator to the floor three times. the MPH thing is ususally a dash controlled item, look there.

I suggest you take it back to whoever did your transmission.

your pcm is detecting a fault need to have computer checked for trouble codes stored in memory

I just fixed the same problem last Friday on a similiar car... Check the IAT sensor... Thats where I would start... Unless you have a check engine light, then start there..

make sure that the timing advance mechanism in the distributor is working freely.

make sure you have ngk or ac delco iridium plugs installed. Also common problem on the 2.2L ecotec is the cat plugging. Easy check is to remove the front o2 sensor (very easy 22mm wrench) and start the car and rev it. If it revs freely now and does not bog the cat is plugged. They are covered fed. emissions warranty 8yr 80k, all gm dealers stock the cats for the 2.2 ecotec.

Throttle position sensor. It's under recall for most Malibu models.

had a problem with a grand prix like that once, was the fuel filter, and injectors, all needed replaced, and it only had 89,000 miles.
Would check fuel filter first. Is it possible you got some bad gas??
