I have a 99 rodeo with 100,000 km's on a 3.2L. I recently had problems with a check engine light on due to the mass air flow sensor and the intake gaskets and a surging problem. I also noticed it was starting to use more gas around that time as well. I replaced the sensor, intake gaskets and the surging seemed to have gone away except the odd occassion it does it on start up. I noticed the gas mileage is getting worse. This morning my check engine light came on after i filled it up with gas. Still seems to be running fine and cant smell any gas leaking.
I need some help as i dont know if it could be a plugged fuel filter, fuel pump maybe going? I read somewhere here that there maybe a TSB for the pump or something? I still have to get it in and see what code it comes up with.<img src="/forums/images/graemlins/confused.gif" alt="" />
