i am at a loss (not financially yet :)
my b20f brick is doing some truly weird shit at idle- sometimes it will just not stay steady-most times it will...it never goes over the 900 rpm i set it at, but it drops and rises intermittently- hot more oft than cold..come to think- it never acts funky when cold...
i tested my injectors and i get all 4 within 2 cc's of fuel in beakers by lifting the crazy k jet air plate and the cold start is firing cold and never when warm.
i have not tested fuel line pressure but im relatively sure its good as i have no problems otherwise and i really dont think i have any vacuum leaks.
all i can think to replace is aux air valve- its getting current and is 1/2 open cold and every time i check closed when warm...i guess im wondering if they tend to act skrewwy even if this checks out..otherwise im gonna guess im losing fuel pressure...timing is dead on at 10 btdc..
any ideas??
thanx!
