Hope everyone had a Happy Thanksgiving! I've been tracing a persistent hesitation and power-loss-under-load problem for some time. I have my various suspicions, but in order for me to better conceptualize the interworking of my cars systems, I need to know what one engine-bay relay and one non-25 amp junction box do. As for the rest of the main hesitation issue, there are a few spots on my skull that I haven't bashed into a wall yet, so when I fill my quota of lumps, and throw my arms up in frustration, I'll raise the white flag and surrender to the much more experienced people here on this board. I still have a bit more research to do, so I don't ask something that's already been answered. I would appreciate, however, if you guys would stop by my photobucket page and have a look at the items in question. Thanks in advance for considering my request.
