started as a P0304, I did the injectors, the plugs and wires, the purgesolenoid. Now Im getting a P0300 and p0443 has me pretty confused. A few months ago I did the vent valve solenoid to fix my fueling issue(Ie pressurized gas tank). Tried everything, also replaced mass airflow sensor. Need a mechanics advice. White smoke and loss of power. Misfiring stumbling and fumbling.

Is there coolant disappearing? Does the exhaust smell like coolant?

jps0039

coolant levels are steady, exhaust smells like gasoline, and its burning oil faster than usual. My dad and I have been colaberating he thought maybe MAP sensor or oil pressure orrr the AFM and it being stuck in 4 cylinders.

did you check your fuel pressure?

jps0039

no I’m am not quite sure I have the tools to do so. I did notice my oil pressure gauge seems to be running lower than normal.

mountainmanjoe

how low?

a fuel pressure gauge is a useful things to have. They can be easily bought, loaned, or made.

If my memory serves me it used to idle around 40 now it’s closer to 25 I chalk that up to the Miss fire. It seems likly that it’s a vaccum leak or something wrong with evap system. I will look into getting one to your point.
