It does it with the air offInstead of a miss, could it be the normal slight shudder felt when the air conditioning compressor cycles on and off. See if it occurs with the A/C off.
No loss of power , no check engine light or no codes with scanner check , nope tach stay at its normal function, but it is a missCan you be more specific, how do you know it's a miss?. Is there loss of power when accelerating or is it just the tach fluctuating?
How many miles on the vehicle?
The PCM continuously monitors if there's misfire, and also if there's enough of it to set a pending or actual code. There are misfire counter PIDs available via a live data scan tool which will tell you if there has been any misfire happening on your vehicle. If those counters have values of zero, then there has been no misfire since the last reset or battery disconnect. But if instead, you want to identify misfire by your gut feel, then full speed ahead.No loss of power , no check engine light or no codes with scanner check , nope tach stay at its normal function, but it is a miss
I didnt say it had a misfire , I said it had a miss or better worded jerkWith no CEL, how do you know that your vehicle's engine is actually misfiring?
I've never seen anyone use the word 'miss' to mean jerkiness (presumably during up or down shifting), but at least it's clear now what you're talking about. And what you're referring to is almost certainly the same transmission behavior that a number of others have described here.I didnt say it had a misfire , I said it had a miss or better worded jerk
