2007 Explorer Sport Trac was misfiring when first started and then would settle down. Now it is misfirng and when I try to drive it, it does quit a bit of sputtering and has no power. Took it to mechanic he said it would be hard to tell if it was fuel injectiors or what. I need to get this fiixed. Would like to know if anyone can give ideas on potential problem or good mechanic in Houston Texas. Help ---

Google “ford p0300” and the other codes. Lots of info. Which engine do you have and how many miles are on the vehicle? ---

Could be a lot of things like a bad coil(s), bad spark plugs, bad gas. Needs to be gone through and diagnosed by a mechanic if youre not mechanically inclined. ---

Check the “Mechanics Files” section of this site for a recommended mechanic near you. Meanwhile, with multiple cylinders misfiring I would first check out the fuel system for clogged filter, bad gas, bad fuel pump, etc. But a recommended mechanic will know what to look for.
