This is a van (2000)used to transport people for leisure. It has 270k. When she is warmed up and rolling the power output is impressive for the vehicle size and weight. A half punch on the gas will push your shoulder blades into your seat.(I've never floored it)
It has an fairly consistent “lack of power issue”. When she is just starting out for the first run. And about 3/4s of the time after she has been sitting at idle for an extended period(already warm). The lack of power is severe. If a hill of note is involved I have to turn around and go the other way.
The lack of power normally is dealt with by pulling over and shutting the motor down. Usually 2 mins or longer is the best. If I am in a hurry and don’t go full 2 mins I get improved power but not really full. She will clear herself up then as we go.
“Refinding” her power always comes with a BIG load of smoke output. She does smoke pretty good when cold, of course. But normal driving not very bad. Smoke is of the whitish to light gray in color.
This has been a problem for the the 3 years I have owned the car. She is cold blooded. When I plan to drive the car I plug in the block heater otherwise I think I am using 2 gallons just to get her warmed up to idle.
I just started using the diesel Kleen fuel additive. Got it at Napa. Haven’t seen much improvement or change of note at this point.
Other than this problem and the wheel almost falling off once…it’s been a perfect rig.
The mechanic has not been able to come up with much. Although at the last oil change the computer code mentioned something about a temperature sensor? I have not yet followed up with him about that.
