Hey today all of a sudden my G started sputtering in idle and has a rough driving experience.
Here arew the codes:

P0300
Random/Multiple
Cylinder Misfire

P0139
02 Sensor
CKT Slow Response

P1147
Manfacture Control
Fuel Air Meter

Just Changed the belts about 2wks ago, oil is still good, radiator fulid is good fuel is holding at a constant pressure.
I do apperciate te help.

 

Take it to forged... Misfire could be alot of things.. Plugs etc.. Looks like you fouled some O2 sensors.. Do you have test pipes?

 

I do have Turbo XS test pipes I am use to the 02 Senser throughing but the others really messed up my day. I am thinking it is the plugs or coil packs I will be checking everything tommorow. Thx for the advice.

 

Got the car fixed, coil pack went bad #5 cylinder.

 

how much for a new coil pack?

 

Got one from the dealership for $80.00 had to travel to Atl to pick one up no one else even had on in stock in GA.

 

I know right the only problem I had was finding a dealership that had one in skock.

 

How did you figure out it was your coilpack?

 

I'm surprised you didn't throw a P0305 code.

 

IWe decided to try the coil packs before we tried to pull the spark plugs. All we did was go down the cylinders pull off 5 of the coil pack plugs and got a change in the motor stability got the the one on the passenger side front and had no change so we figured out that was the one with the problem. Switched the coil packs around and pulled the coil pack plug again and had no stability changes in another cylinder after coil pack switch.


We ran a good diagnostic checked all of the cylinder one by one but nothing showed but the P0300 code.

 

Good job finding the problem.. PMed..
