Question about 2000 Pontiac Grand Am GT

1 Answer

Service Engine Light on and sometimes flashing

My service engine light has been on for months now but the car yields no obvious problems. When I accelerate on the highway, the light begins to flash.... I took it to an auto parts store where they read off some codes but didn't give them to me and turned the service engine light off. The light has appeared on again and I don't have a owner's manual to know what the codes mean so what should I do?

    I have a 2000 pontiac grand am gt. I bought the car in july of 08 and 2 weeks after i bought it the service engine light came on and has been on ever sense. But the car seems to be running fight i have seen no problems with it being on. could that be from. well the guy i bought it from told me there was one light still on the dash that was on and it wouldnt pass inspection till it was off. so he took it to the a dealer and they put a brand new battery in it and it shut off. well after it passed insepction the guy took the new battery out and put the old one back it and that light has been on ever sense. Could that be why it is on? something to do with the battery.

When accessing a highway from a frontage road access should you begin accelerating as you approach the highway or wait until you are on the highway to incresse speed


Accelerate while on the "on ramp" until you reach the speed limit + posted on the highway... this way when you reach the highway you will be going the same speed(or close) as the other vehicles ..you can blend in easily.. and NOT cause an accident by going too slow!! On the way down the "on ramp".. start looking at the traffic coming on the highway to find an opening to ease into safely. Use your mirrors and BLINKER... (its easier to slow down a little than speed up)

While merging onto the highway when my car hit 3 and 4th gear the engine seemed to "stutter/misfire" during harder acceleration. Check engine light also flashed briefly during hard acceleration. Dur


Could be a transmission problem or something as simple as bad spark plugs.
The engine is under the most load when RPM is low and you are trying to accelerate, such as when it upshifts.
You should have the computer checked for trouble codes and hopefully that will point you in the right direction to test.
If the spark plugs have more than 50,000 miles of wear you might start with replacing them.

Traction control light comes on and Check engine light when accelerating to highway speed.The performance is not affected most of the time. I did an engine diagnostic, and the only code that flashed...


cleaning the sensor may not have fixed problem --also check connections with abs and speed sensors but recheck code and if still maf possible wiring ir sensor failure

Struggling to Accelerate immediately after starting engine


Most likely there is a hole in the air tube. Open the hood and check the rubber tube on top of the engine. If there is a rip, just cover it with some heavy duty tape and it will help on a tempory basis.
