But I cannot determine which forum it fits in.....I'll post it here, someone can move it to appropriate forum please????? Or perhaps a troubleshooting forum would be good?
Here is my problem:
Last night and this morning I noticed what I think to be a slight hesitation. Here are the (some perceived) facts of the story:
2000 Z28 (which of course means LS1), approx 57000 kms of use, M6.
Just after coasting in 5th gear for a short time and then applying light throttle, the engine seems to pause and then continue on. No jolting response after the pause, just seems to take a few milliseconds to think about it and then proceeds. Happened both times at around 1600-1800 rpm (about 60-70 kph) in 5th gear. That is the lower range of 5th gear, but it doesn't sound or feel like the engine is being lugged. I have driven this speed in 5th gear many many times over the past 3+ years since I got the car and never noticed this.
It seems odd that it only happens during these conditions (being rather cold as well right now), so I would doubt ignition or fuel.....maybe the ignition control modules are just cold?
