Hi all: I've got a 92 Cutlass Ciera that, since undergoing a recent major
tune-up, has been exhibiting a cold idle problem described as follows:
About a minute, or so, after a cold start, when the initially rapid
cold-idle speed normally ratchets back to warm-idle speed, the engine
starts
to sputter and then dies. If the engine is forced, with the accelerator
pedal, to idle at a slightly higher speed for another minute, or so, the
problem disappears and the engine will then slow-idle normally. If the
car
has been operating normally and is then parked with the engine shut off
for
an hour or so. the same problem is experienced immediately on restart. In
all other respects the car seems to be running perfectly normally and no
other problems are noted. So the problem seems to appear only within a
very
narrow range of relatively low operating temperatures, but the GM
dealership
that did the tune-up has so-far been unable to isolate the cause of the
problem. Any suggestions re. possible/probable casuse(s) of problem
described above would be greatly appreciated. Thanks for your replies!
