I have a 76 280z that runs like crap. It's running incredibly rich from startup all the way thru max. Did a little searching and found a EFI site with some troubleshooting tips. Metered the AFM connector at the AFM and found what I think are the air flap pot points. They're the only 2 that had continuity. showed 53.5 ohms with the flap closed and they went open after a few degrees of travel. I'm thinking this isn't normal..... After reading a few threads on here as well, I pulled a cracked 3/4 OD line from the valve cover to the plumbing over the intake manifold. It's about a foot long line. What I found was this bottle brush wedged into the T connector downstream of the valve cover. I'm thinking this isn't normal either..... Any ideas??

nope, it won't. and thermistor is correct. they were all over the airplanes i worked on. thanks!!

Thanx Stephen.... i was leaning that way as well. I hate chasing electrons.....is that switch NC or NO? If it's NO, I should be able to jump it and fool the system.

Great idea!! First question it appears.....just bought a 76 280z. runs well for about 15 minutes and then runs rough. feels like it's running rich and flooding out. i'm leaning towards a temp switch, but it doesn't sound like the thermotime switch is the bad guy based on what i've read here. any other ideas??
