1800E mixture lean over 3000rpm 1800

Chris, thanks, I did check the TPS. Disassembled and cleaned the contact surfaces, etc.. However, as I understand it's function, besides the idle position and fuel cutoff, it's function is to add incremental fuel enrichment during acceleration. I.e. each increment on contact made adds an additional injector pulse (all injectors). This seems to work, as when under load, I can witness richer AFR during throttle opening. I didn't think the last contact at WOT maintains any additional fuel enrichment. I have read later D-jet TPS incorporated an added contact for WOT position that the 1800E does not have.

Anyway, C1800 steered me to confirm which MAP I was using, and it was not for an 1800E. You can read elsewhere in my replies. Thanks. Rick
