IIT: We discuss our friend Murphy.
A few of my favorite moments I've shared with Murphy this spring/summer:
Original Problem: MS started randomly running on 2-cly. The only cure seemed to be physically hitting the MS unit to restore spark to all 4-cly.
Cure: Swap CPU to spare MS mainboard.
This lead to Problem: Idle erratic/problematic
While Diagnosing: The rubber cap on the back of the head burst open while idling for about 45 minutes. Determined the IACV died.
Cure: Replaced rubber plug with a hose from the back of head to the IM port on #1. Replaced IACV valve.
This lead to Problem: LC-1 is now on the fritz. Once warmed up it sends random values rapidly to outputs. Believe sensor has failed.

Since this is a pity party....problems with my car this year:
-Car was running great, and would dust Mustang GTs and WRXs, I was happy
-motor I swapped in two years ago dies due to oil ring failure, massive amounts of smoke
-CAS dies first day on the road with hustler's replacement 1.6L (which was last running the day he got dominated by a soccer mom in a Prius)
-I have problems with injectors, while simultaneously selling my back-up set, and see four sets of injectors, including an insanely cheap set of RCs go through my hands, swapping three times due to obligations from sells, and am left with a mix-match set of 550s that run horribly
-I reset base timing, but forget the "-10*", which leaves me at a static 10* of timing for the next 300 miles. I think I got smoked by a douche in a Mustang that day, and the guy followed me for a mile, pointing and laughing.
-downpipe gets tremendously hot, and needs a welding repair
-cam seals die on new motor (only gasket or seal I didn't replace during swap), and car gets parked since it loses a quart a day
-part out follows
Luckily some nice members stepped in and helped a few times, as well as the usual advice.
