Engine/Transmission (1998.5 - 2002) Engine lopes when I let off throttle

[CAfricano]

When I let off the throttle, my engine lopes until it reaches idle. Any ideas?

Define "lope"
Mine does not immediately return to idle when let off the throttle (in gear and underway). I would not call what it does a lope though

If you are highly fueled the engine can run differently while the fuel catches up.

Fill in your signature so we all know what you have so we can get a better feel to help with suggestions. Bigger injectors will cause this.

If you are talking about a 50 RPM or so surge after you come off the throttle, mine does that also. Ussually surges once then goes to idle.

Mine seems to have this "lope" every once in a while when in the throttle hard. It only seems to happen to my truck when the wire tap box is on and after a strong WOT pull push in the clutch and it will kinda chug up and down ~50 rpm quickly for 3-5 seconds before smoothing out. My first VP did it and the 2nd one does the same thing. If I get back on the throttle it goes away and runs fine.



Hope this helps.
