Hello all!
I really need your help. My Northstar is sick far from home and I'm lost.
A few weeks ago I started getting the P1101 P0068 P0420 codes however performance and econ stayed the same so I assumed I needed a new throttle body or the software upgrade.
Two days ago, the tank was very close to "E" when I pulled into the gas station to fill up. As I stopped at the pump, the car ran a little ruff. I filled it up and it would start. After some working the peddle, I got it started but it wouldn't idle and had a very bad miss up to 2000 RPM. I drove about 50 miles at 60-70 MPH with near normal power and typical MPG but it didn't clear up.
After checking the forum and internet, I replace the spark plugs. I also put water around the intake and injectors but found no leaks. I then removed the intake to check for leaks and cracks. (didn't find any) I didn't have an injector tester however they hold pressure and didn't look too dirty. I Got it all back together and still have the hard start/hesitation/miss problem with the following codes P0300 P1101 P0301 and sometimes P0068 P0106.
Any thoughts? What else should I check before sending it to the dealer? Do you think it is related to running low on gas or just coincidence?
thank you very much in advance for your help
