Here's the background- I was driving home one day with a lifter that started tapping the day before. The engine runs a bit sluggish off and on, nothing new- I've always assumed it is the temp II sensor and/or the AFM. The sluggishness didn't bother me much. I was on the gas pedal completely and looking out the rear-view mirror (a habbit I got into after dumping all the oil out the back end of my diesel a couple times) when I notice a big plume of white smoke! I left off the accellerator and shut off the engine immediately. I was close enough to home that I coasted up the road and into my driveway. A day or so later, I started the engine to see how it behaved. Simply noisey lifter, nothing else seemingly out of the ordinary. Days passed, and eventually I replaced the lifter.. Now, I drive the vehicle and the lifter is still noisey now and then. I probably need to readjust the valves now that it filled with oil. (I failed to fill the lifter before installing it. LIve and learn, right?) Anyhow, Tonight while driving to dinner with the family, the engine felt very sluggish again. I was on the accelerator fully (and looking out the rear-view-mirror) when I say the plume of white smoke again! I let off the pedal a good bit, and the smoke immediately stopped! What in the world could this be? The engine is relatively strong. It runs evenly. Note, both times it's done this, I was full-throttle (ie, enrichment switch was closed). Any ideas?
