Re: 2000 200 efi smoking bad and running rough
Bruce, Charlie is leading you to a problem with intermittent fire. Total loss of fire on a plug won't cause smoke because the cylinder never burns the fuel. It would also be accompanied by a fuel sheen on the water.
Intermittent firing is one of the hardest things to troubleshoot. It's hard to tell if it's your meter or the component. You really need a scope to see it clearly. Most of us keep our scopes in our back pockets.. Mines a Visa, some prefer Master Card.
But before you start throwing parts at it, check that TPS setting and if that isn't it, then have the injectors serviced. Those are things your should be doing on a regular basis anyway.
