My check engine light came on and the diagnostic code is PO302 for cylinder 2 misfire. My mechanic checked the spark plugs and wires and ruled out the coil. He cleaned out the fuel injector for $150 and it worked for a day then the light came back on for the cylinder 2 misfire again. My mechanic says I have to replace the fuel injector for $290 which may or not be the problem and it could be the computer. He says the only way to know is to replace the injector first and if it doesn't work to pay over $1000 for a new computer. What do you recommend?
