When I start my car up in the morning it starts rough and revs to about 1200 rpm. It starts to smooth out as the rpm starts to climb after a few seconds. The car then smooths out and rpm is at normal idle. By then my cel is on.
The two cel codes im getting are P0303 and P1399
Iv replaced the spark plugs and wires. Getting a distributor cap soon. Havent replaced the rotor since its just on cylinder 3. Cleaned out my EGR valve. Iv recently changed my radiator and radiator fan switch since the radiator was cracked and fan wasnt working. Also reset my ecu after all this and still get a bad start in the mornings, but seem to start fine later in the day when iv driven around awhile. Just on a cold start I guess.
Any suggestions would be greatly appreciated.
