One day check engine light came on and got the p0303 ccode ok bought new wires plugs and ignition coil. Replaced it and same thing still. Had some people check it out for me and couldnt firgure it out.I tried swaping plugs and also swaping the injectors and same thing misfire on number 3. Its happens on them morning cold starts then it will run fine afterwards it warms up. Had another place check it and they said it has compression spark and the igectors are working fine because they checkd it with a noid light. But when they sprayed down the wires on the part its connected to the ignition coil you could see sparks and the engine stalling like crazy. So he told me to replace the wires and coil so I purchased it straight from the kia dealer and replaced it and it still misfires. Says number 3 misfire p0303. Im out of answers dont know what to do next please help.
have the same problem?
