My Pontiac G6 won't accelerate at all
I have a 2006 Pontiac G6 with about 110,000 miles on it. I had the oil changed and after
I parked it, it would not accelerate at all when stepping on the gas pedal. I put a new
throttle body on and problem still exist. It starts and idles rough, will go into gear, no
acceleration at all.
Is the tps new (throttle position sensor)?
If you can pressure test file pump.
The throttle position sensor comes on the new throttle body as one unit
Check fuel pressure.
No check engine light ?
Engine light is on codes: Current Fault Log ------------------ P0030: HO2S Heater Control Circuit (Bank 1 Sensor 1) P0036: HO2S Heater Control Circuit (Bank 1 Sensor 2) P0050: HO2S Heater Control Circuit (Bank 2 Sensor 1) P0056: HO2S Heater Control Circuit (Bank 2 Sensor 2) P0068: Unknown code - More information may be available on the web P0102: Mass or Volume Air Flow Circuit Low Input P0443: Evaporative Emission Control System Purge Control Valve Circuit U0107: Unknown code - More information may be available on the web Pending Fault Log ------------------ P0053: Unknown code - More information may be available on the web P0054: Unknown code - More information may be available on the web P0059: Unknown code - More information may be available on the web P0060: Unknown code - More information may be
Do a ( Exhaust System back pressure test ) you can get this kit at most parts stores. If your catalytic converter is clogged will cause the same problems you are having with your vehicle.
Frank-- how did this turn out? I am having the same problem and need help.

Check for a blown ( ETCS ) Electronic Throttle Control System fuse.
Were the Etcs control system
Try changing the accelerator pedal sensor

Change ur tpps.
I have a 2008 Pontiac G6 GT 3.5L - 160,000 miles. Check engine light came on, codes were : P0420 Catalyst System Low Efficiency (Bank 1) P0101 MAF Sensor Performance P0496 EVAP System No Flow During Purge My car deteriorated within a week. It would not accelerate past 40mph when pushing the pedal, it would increase slowly to 60-65mph on its own slow pace. A couple days later, it went from 60 to 40mph and had a horrible smell. Towed to a shop, there was an exhaust restriction. Ended up being the large catalytic converter. It was clogged (due to the guts of one of the small ones blowing out into it from what I understood). I hope this helps. This car has been a nightmare, leaks, electrically going haywire, etc.
