MODEL: Sunfire SE
ENGINE: 2.2L OHV Vin 4
DESCRIBE ISSUE.... Engine is lacking power while accelaration. I just had fuel pump replaced less than 2 weeks ago due to DTC P0171 code. After pump was changed, car ran great until Sunday afternoon ( 3/12/17) . Car has no new dtcs, no power accelrating hard, but baby it, it will go. Abs light is on since i got the car on Feb 23rd. Now trac off light comes on while driving as well.when it happened i had the ac, radio, lights, and wipers on. I checked the alternator at battery. Everything off, its at 14.3 volts. All the above, 12.6v at idle, 2k rpm, down between 9 to 10 volts. Engine is shaking badly as well. So any ideas? Me and my buddy are completely stumped and i got no car now to get to work. Thanks in advance.
Low on power and shaking badly? Take compression readings.
