I'd have the shop that messed up pay for an oil pressure test at another shop, and get everything documented in case you need it later. Yet another reason I like to DIY, even though I'm probably loosing $$ with the opportunity cost...
How did you find an Infiniti forum for your Ford question?

Heath, I quess it's driving ok now. I picked it up from the shop yesterday afternoon..... now there is an engine "vibration" when the engine is at 1400-1500 RPM's that the mechanic showed me.... I'm really not sure if this vibration is new... I don't think so because I keep my truck in top-notch shape and I think I would have noticed it. If you place the truck in park and rev it up to 1400-1500 RPM the engine vibrates OR if you're driving at a speed while the engine is at 1400-1500 RPM you can feel the vibration.

Please explain what you mean by "oil pressure test".
I found this forum by doing a google search for "auto mechanic forum". I have joined a total of 4 mechanic forums in order to get lots of different opinions... I am a girl and don't know much about such things.
Thank everyone for replying!
