Mine started to 'stumble' at about 7000 miles...it turned out that I had two plugs that were 'glazed'!....weird that a lot of people have been getting the same issues with this! [:I]

my dreamcruiser series 2 had the same trouble with only 13,000 miles on it. the shop could not find the issue for two days (even thought the engine light was on)!. it was determined to be "spark plug number 3". they replaced the spark plug and now it run fine (for now!).
good luck![xx(]

gatorgal1, welcome to the forum!!

Interesting to see this problem. I had the same thing happen at 16,000 miles. Engine light on and rough idel. Dealer replaced #3 plug. 26,000 miles and same thing happens again. Back to dealer and they replace #3 plug again. Seems strange that the same plug fails again. Could this possibly be the spark plug wire also?

P0303 means that the crank sensor measured a drop in rpm and calculated load value only during the power stroke from cylinder number 3.
This should mean that the #3 injector is firing. The coil fires 2 cylinders at once, therefore a waste-spark ignition system, so the coil isn't suspect.
That leaves the secondary ignition system, ie: plugs & wires.
Either the wire is faulty or the plug has failed. You can swap the wire from the #2 cylinder to see if the fault code moves to a P0302. But, because you have to remove the intake manifold to replace the plugs, you should do all 4 of them.
The instruction guide is written at www.ptdiy.net

By 15K miles, my first PT plugs had a gap that opened 18% out of specs!
