This condition just started. At morning start the engine runs rough or stumbles. After about 2 miles everything is smooth again. Performance and economy is fine. No codes are present.

Recently replaced air cleaner, plugs, wires, rotor and cap. Injection system cleaning has been performed too. Any suggestions? Any is appreciated. Thanks.

 

Just a thought. Did you by accident leave the tube that runs from the RH V/C to the air cleaner OFF. I have done that a few times & our 97 would stumble on take off sometimes die but restart easy. After it warmed up it was not as noticeable.

 

Hello 4x4. I will have to check that this afternoon. Yesterday it didn't want to start but did. And again after a few miles just smooth as could be. It set a code of P0300 but cleared after it started running good again. Appreciate your advice. Thanks.
