If you mean the knob on the left side of the steering wheel then thats the idle control. You turn it all the way CC to bring the engine up on high idle. This high idle could be the reason for the jumping.
Yea, that is telling you that the engine is healthy. They all did that when new.iNeon - 1/19/2005 12:15 AM
another question and ill leave yall al i fix the first batch!
is the oil pressure supposed to be maxed out(touching the top needle stop) when it is going?
it comes down to about 2/3 when it is sitting at a red light if that has anything to do with it!
