Default Bucks only on acceleration

I have a 2003 F150. A couple months ago, as I was driving, everytime I pressed on the accelerator, there was a clicking noise coming from under the dash on the passenger side. I took it to the dealer for service, and they replaced the vacuum reservoir system and a couple spark plugs. Now, I have a new problem. When I soft-accelerate (don't press the gas pedal to the floor), it bucks and skips and is really scary when you're on your way home to the country 30 miles from civilization at night. I'm afraid if I take it back to the dealer for service, they'll come back with a ticket saying "unable to duplicate customer concern." If I have some idea of what's causing it, I can ask them to check that. Can anybody help me?

Default Next question - passenger side airbag indicator light

Thanks very much! That makes a lot of sense. I'll have that checked out.

Next question:
About 2 months ago, I took my truck to a car wash. They did a pretty good job cleaning, but I noticed afterward that my passenger side airbag indicator light on my dashboard (?) was on. The dashboard is where the speedometer and other indicator lights is located, right? Is this something I should get checked out?

That's the very first thing I did -- several hundred times, actually. But it didn't work. The "off" light won't come on anymore, and the airbag indicator light stays on. At first it flashed, now it just stays on when I start the car...truck.
