My 87 5ktq engine has taken to stalling when I am running the air
conditioner and letting up on the accelerator. Doesn't do this if I switch
off the climate control prior to slowing down.
OK, this is what helps: I switch off the CC whenever I expect to stop at a
sign or a light. And I backed off the throttle screw a few turns, which
brought the RPMs up to 800 with CC set at AUTO. Now sometimes I can stop at
a light with CC on AUTO and not stall.
I suspect the deceleration valve, and/or the relay that speeds up the RPMs
when the CC is ON. But I don't know where these items are located or how
to test them. My Bentley shows them in diagrams, but really getting to them
is another matter. Car runs good otherwise.
All replies appreciated. Doyt Echelberger
