running rich
I have a 90 camaro with a 3.1 it will not stop running rich. the coolant temp sensor and oxygen sensor have been replaced and it is not setting a code. My question is what else helps determine the air to fuel ratio?

Re: running rich
Update: it doesn't do it all the time just when it gets hot. when it hits 180 its like somone flips a switch. it starts spitting and sputtering, it also smokes black out the exhaust. Anybody have any ideas?

Re: running rich
check your fuel pressure regulator and also check your vacuum lines.
