Question about 2000 Pontiac Grand Am GT

1 Answer

2000 Pontiac runs fine on the highway but when i get to town it won't accelerate at stop lights. It sputters and acts like it isn't getting gas sometimes dying. I have resorted to turning off the moto

Check enging light, brake light, and ABS lights are on and have been for about a year. It also sputters in reverse especially up a grade.

SOURCE: abs and traction control light faults after a brake job. 2005 Pontiac grand prix

You have a bad sensor at one of the tires that need replacing that operates ABS and traction control. If you take it in to a shop it will run $130 but they can find which sensor is causing the problem. But if you do it you might have to replace all 4 sensors to make sure you got the right one. Every hard to diagnoses. Its better for the shop cause they can get electrical read outs for each sensor.

its really a GM car, end to end.

no engines codes, is not true i bet ,
some codes take 1 to 3 trips, or dont store
and if you get CEL glowing, driving too much can clear the codes.
so.... that means you must scan it failing. see?

sputtering is misfiring (bad spark or way to rich fuel)

why do you jump all over fuel first.
try spark FIRST no gas engine burn fuel right with bad spark'
not one, and is first not last.
ever heard of tuneup, done one in last decade.
you know, spark parts? plugs and wire top list.

in the rules of basics its:
engine good, (compression test pass, and vacuum looks ok)
then spark
last fuel
why do that backwards/?

You have a bad idle air / idle sensor. Your car believes that you are in idle at all times so when you come to a stop the engine floods. When the fuel evaporates you can drive again. Drove me crazy when it happened to me.

If it is running bad enough to be backfiring, the Check Engine light should be on. I would start with scanning the engine computer for fault codes.
