Vibration during shifting
I have a new vibration in my 2003 Excursion, occurs during the last shift around 45 mph. The engine is also running very rough and the engine light is now on. Not sure if the 2 issues are related, but they both started about the same week.
A buddy of mine said he had a similar experience w/ his 99 Expedition and it was the fuel injectors. I'd rather it be the injector than a transmission issue. Thanks.

It is almost certainly an engine issue, not a trans problem. Most of the time it is a one or more ignition coils and/or spark plugs.

Thanks. I most likely still have the original plugs at 120k miles so that's probably it. Still saving up to have them replaced, LOL...

Do it yourself. Any slight load at low rpms and high speed can cause that type of missing.
