If you let off on the gas or cost it tends to buck and jerks more. If you step on the gas it seems to reduce and/ or go away. This can happen at all speeds. Again the computer showed 2,4,6 had a miss on that bank. After the problem re-occurred the next computer test showed no codes. The check engine blinked on and off at 1 time when we were coming to a stop. Went off after we re-accelerated and has not come back on. Again plugs were changed at the same time we did a front wheel bearing.
If code came up 3 cylinder misses is that telling me that all 3 coil packs are bad? or can 1 bad coil effect the whole bank. Do you have any idea the price for a coil? or what the job would cost?
We changed the coils as you suggested and the XL7 continued to do the same thing. We broke down and took it to a dealer and they told us that it was down 2 quarts of oil. So they did a cleaner on it and changed oil. They report that they drove 29 miles and it has missed at all.Picking it up tomorrow, I guess we will see if the problem is fixed.
