You need some kind of scan tool, as the paperclip trick doesnt work.

You'd be surprised at the crap those things monitor these days. I spend $70 diagnostic fee on my 97 Montana to find out that I'm getting "random cylinder miss." Duh! I could have told the stupid computer that just by listening to the engine!
Turns out, it needed fuel injector cleaning and new plugs. Shop wanted $500 to do it .. eh, no thanks. Payed $80 for fuel injector cleaning and replaced the plugs myself, as well as the wires.
I don't know about your problem tho, just thinking that something serious might have happened to the engine and the computer is spitting out misfire codes. On the other hand, you may elect to spend a diag fee.
