my crx with b16 swap in it is running really rich i cant figure out why. its not throwing any cel codes can anyone shine a light on the possiblities?
thanks

 

ecu?
timing right?

 

what exactly such as map sensor o2 sensor exc. would be cousing it to run so rich it runs choppy untill you get to high rpms then its fine.

 

is it throughing any codes?
if not check your dizzy timing mine was doing this

 

its not throwing any codes whats the dizzy timing?

 

ok i figured out what the dizzy timing is could it be a vacuum line problem though?

 

don't think a vaccum leak would do this at all....

 

Just curious and also I don't mean to thread jack but how can I know if my car is running rich? Will it have the gas smell smoke coming from the tailpipe?

 

yeah thats what mine is doing and its running crappy at low rpms but once you get near 5 it runs good

 

my spark plugs are all black as well is it possible i have it is a dx and i had to wire in the injectors and everything is it possible i have wires criss crossed somewhere? if so what ones would do it?

 

I haven't driven mines much after the new piston rings install. Only have 40 miles on and it been sitting for 2 weeks. I need to drive it more to see. I think timing would cause that or a bad fpr?

 

check your timing!!!!!!!!!!!!!!!

 

Is your fuel pressure regulator vacuum line hooked up to the corect port on your intake mani? If u dnt have that hooked up right it would dump a lot of fuel and since its running the same percentage through all rpms it could be something with our computer. If its reading a wrong rpm it will run as if its reved out
