Re: Hesitation off the line when cold.

["Jeff Goldberg" <jeffgold@erols.com>]

4kq's don't have them.  But I don't have anything more profound to offer
other than maybe test idle switch, clean air plate and cone, and general
engine housekeeping.

Also, when you say "over-riching" the mixture, since when he car warms
up this is impossible, ecu/oxs return the mixt to correct, perhaps
leaving it a little rich when cold could be the cure?  What does the DPR
current read durig warm up and then when qarm?
==========================

Huw,

I will try testing this. Don't have an Ohmmeter, but soon to purchase one.
Yes, you are right that riching up helps, and the ECU takes over when the
car warms up, but riching to the point of problem elimination causes very
poor acceleration from a stop as well as some other detectable negative side
effects.

Thanks to you and others for input towards problem resolution. Will keep you
updated as to solution.
