The codes are KOEO 31,41,66,95
KOER 12,41,91,31 i already swapped out mass air sensor and egr valve as well as egr valve and as I stated before I checked for leaks I have no issues there as well
alright so my fox has an issue with its idle on a cold start it'll jump up to atleast 1500-2000 Roma almost stall out but idles prettt normal after driving for an hour or stopped at a red light the cars rpm will drop about 150 Rpms and start idleing roughky but won't stall out accelerates...
I know how to route them and all but my only question is would there be a problem with the line from the fuel tank being directly connected to the intake. I will get the cansiter soon.
Just got me an 89 5.0 come to inspect it I realized that the fuel vapor line is connected directly to the intake instead of being on the canister and purge valve I want to know if this would cause problems at all the idle is a little High but if I take off the lines and block them off the idle...
Just got my 89 vert 5.0 I noticed that the fuel vapor line that goes connected to the charcoal canister is connected directly to the intake manifold would this cause problems? If I remove it the idle drops and if I cap it of it idles a bit rough. The car also does not have the canister.
