Hi,
I just started having this problem today. I have no power and my car runs very rough/sputters on CNG. I can floor it and it revs a bit but doesn't move much and then surges. I couldn't go faster than 50 on the freeway. I stopped to pull the fuze to run on petrol and the car runs fine with all the power it needs. I got my scan tool and checked to see what code was coming up and it was a P0133 O2 sensor code that didn't make much sense. I cleared the code and tried to run it again on CNG and it came up instantly with P0134 O2 code error. I am not sure what is wrong. Has anyone else had this problem?
2001 Chevy Cavalier CNG/Gasoline
Plugs and wires less than year old. Has run great since Oct. of 2008 when I purchased it.
Thanks,
Wayne
