Engine Performance problem
2004 Oldsmobile Alero 6 cyl Front Wheel Drive Automatic
hi guys i hope you can help me. my alero hesitates
and kind of surges while traveling on the highway. she starts up fine and runs good but after traveling a few miles on the hwy the car rpm drops (about 3-400 rpm) and back up again. this continues until i pull over off the road. while in park i raise the rpm and notice the surging continues at 1200-2100 rpm. as i start to move again it runs like that even at slower speed. i tookthe car to the dealership (by the way no check engine light/service engine soon light comes on) and they checked for codes (none found) and ran a diagnostics with no problems. the y changed fuel filter and "flushed" the injectors. later that day it sarted happening again. i changed all plugs and wires and no change. i just replaced fuel pressure regulator and still no change. i dont want to take it back to dealership because no codes are showing and their way of troubleshooting is to replace items instead of trying to properly t/s and repair. this will become very expensive and i cant afford that. please help!! thanks!!!!!!!!!!!!
