Hesitation event..................

[ke4yyd]

I just purchased a baser Vibe and I noticed a peculiarity. When driving at a slower speed, say 35 mph, and I accelerate slightly then let off the gas to maintain the speed I notice a hesitation. I observed that the tach will momentarily drop to 1000 rpm and then return to the normal rpm of 1700 rpm or so. This seems to be the culprit. The dealer service manager said this was a normal occurrence with this engine and autotransmision. Have others experienced this phenomena????

This does not sound quite right...Is this a new Vibe or a used Vibe? I assume new...

It could be possible that you are hitting some condition that makes the auto tranny shift, then decide to change back. I have a manual tranny vibe, so I can't try the scenario to see how mine behaves. Assuming it's a new vibe since your first thread was about some abbreviations on the dealer invoice, then it also means yours is a drive by wire, so maybe the computer is designed to let up a little off the gas when shifting to keep things smoother, or something like that. So I can't really say. One thing you could try would be to go test drive another automatic base vibe and see if it behaves the same way. If it does, there might be some design reason for it acting that way.

OK, this is a new Vibe with 83 miles on it. I noticed today it was not as pronounced so if it is like my last vehicle the computer has a memory for the tranny that learns your driving habits and maybe that is it. It would seem to me if it was normal, as the service tech said, others would would have noticed it also.Thanks guys, I will report back if anything else develops.

Think you posted "A request to Vibe owners". I concur with the poster that said the drive-by-wire system that controls the throttle is causing the problem. Take it back to the dealer and tell them you suspect the throttle is not calibrated correctly or that the throttle sensor is suspect. Sometimes speaking to a service manager in his lingo sends the message that "I'm on to you so don't pacify me with your, they all do its". Keep us posted if you go back to the dealer.
