Well, all is not well in Scummit-town . I seem to have developed a miss of some sort, seems like either a fouled plug or dead injector. It idles fine, almost too smooth actually, but starts to *Brrrrrrrrrrrrrrrrrrrrrppppppppppprprprprpprrrppppppp* at part throttle on the way to boost. Its too dark right now to check anything, so the car gets parked for a few hours/days until I can get some new plugs. I figure it is easiest to start with the obvious and then work my way up. If worse comes to worse, my datalog cable arrives early next week and I can figure it out that way.

*sigh* I guess its time to REALLY learn about these cars.

Anyone have any ideas or experience with something similar?

i had a problem similar and replaced the plug wires and it worked perfect. almost felt like a new car.

It's important on our cars to make sure that the plug wires do not cross each other. If they do they can cause a misfire. This is the reason behind all the little arrows cast on the rocker cover which tell you which way to fit the spark plug boots. I used a few cable ties under the spark cover plate to ensure they dont move - I had a serious miss on the dyno because of this last time. Worth checking the simple things first.
