Vehicle running poorly

Hi Uglyone, Welcome to 2CarPros.

The bucking you describe is generally caused by a timing issue.

It would be helpful to me if you could post the code numbers so I can look them all up. Then Ill see what we can do to get you going.

And off we go!

P1201 OBD Code Definition:
P1201 Injector Circuit Open / Shorted †Cylinder #1
P1201 OBD Code Description:
OBD Code P1201

Injector Circuit Open / Shorted †Cylinder #1

OBD Code P1201

(Alternative Fuel) Gas Mass Sensor Circuit Range/Performance

OBD Code P1201

Fuel injector No.1 circuit malfunction

OBD Code P1201

Injector circuit open/shorted †cylinder #1

OBD Code P1201

Injector circuit open/shorted †cylinder #1

P3901 reads as again injector #1 issue and cam position sensor circuit low.

I have found info on both the C1921 and the P3901 that refer to variable valve timing. If your car has a VVT system Both these codes would apply to it.

C3000 is a code for unauthorized or illegal system modification. IE aftermarket chips or having someone use a scanner to alter computer performance functions.

I dont know if you have had this done, but if you have this is likely your issue. PCM reprogramming can cause many issues and even damage if done wrong or incomplete. If it is incomplete the PCM will try to compensate for the changes which could result in damage to many things. Or it could just confuse the PCM and by it trying to fix things kills performance.

If you have not had this done and you are not using a plug in aftermarket chip I would suggest having the dealer try re-flashing your PCM. If that does not fix it, Given the odd codes and situation I would look at a new PCM.

Let me know what you find out.
