Looks great. BeenJeeping for 35 years
Wow. Totally normal that a new part needs "work" to function properly. They should call the place (probably in China) that makes them and modify their production process. BBK used to be good...20 years ago anyway.I feel like I finally worked some bugs out with the 5.0 swap. I was getting lean error codes of 136 and 172. So I started to look for vacuum leaks. I bought a smoke machine and it paid for itself instantly. First I had smoke coming from the charcoal canister. I had the fuel tank and breather lines crossed. I drove it around and still not right where it would die on hard stops.
Afterwards I ran the test and got smoke out of my brand new 65mm BBK throttle body. I swapped out the original unit and smooth as butter. Besides causing a vacuum leak and making a VERY loud squealing noise I called BBK direct. They said this is totally normal and they don't seal properly and I need to sand down the sharp edges in the throttle body to stop the noise. BBK is JUNK in my mind and will never buy again.
I have their shorty headers and they are nice and beefy. I don't know why I read across the internet that some leak and some don't but regardless, my tailpipes were spitting out water because the extra air was causing a lean mixture and running hot ashy plugs.Wow.

Thanks, yes the same booster setup.Rusty is looking great! Is that the same booster/master that was on when you bought it? I installed that as it originally came with manual brakes.
The brakes were much stronger than the factory power brakes on my 8. That master has a larger bore than the factory power brakes with a dual diaphragm booster. It shouldn't have much travel in the pedal (due to the larger master), but I remember being able to lock the brake more easily than with my factory power brakes. 16" of vacuum should be enough and is pretty good in my opinion considering your elevation.
Have you checked the ECT (engine coolant temp) sensor?Opinions please... based upon my build with the. 1995 302 with the OBD1 codes, I am running lean on both banks with an error code 136 and 172. After smoke test for vacuum leaks, O2 sensor test, cleaning the mass air flow, and fuel pressure test, everything is perfect. But look at this plug, is it showing lean? Any other ideas?
