Lately I noticed that the engine was having a bit of a stumbling problem, when I was racing up the street and I shifted into 2nd gear, the engine would stutter around 4000 RPM. I thought maybe it was some dirt in the fuel filter; no big deal. Only happened a couple of times, and always when I shifted from 1st to 2nd. Normal driving seemed fine. In fact, with my heavy foot, I didn't even notice any loss of power, really.
So today I popped the hood to check the oil (because I forgot to add some last time it was low) and was looking over things. Hmm, I thought maybe I should take off the air cleaner and check out the ol' Quad. What a beauty... WHOA! HELLO! One of my plug wires is off and just resting on top of the distributor.
Ok, so now I better plug it back in, check all the other wire connections, and pull and replace the fouled non-firing plug.
Hmm, maybe now would be a good time to switch to HEI
