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!
