92 cx with ls swap. yea im burning fuel like crzy, and there is so much pressure coming out of the stock tailpipe and the smell from it is just like gasoline.

im getting a code 3 but my map sensor is good and its plugged in right, it's just i dont know where the vaccum lines go. i got 3 lines that dont go anywhere. the nipple next to the map sensor, a line from my brake booster or mc i believe, and a line on the top right of the intake manifold that is hooked up to a sensor

my friend said that is why its making me run real rich and throwing a code becuase my lines arent hooked up right, so i have 3 lines where do they go?

anyone? code 3 wont go away, i tried plugging up the hole and still throws code

yes with those three lines off one of them could go somewhere that controls air to fuel just search online for vacuum diagrams and i am sure you will find one it should solve your problem if you get those on correctly

so all those lines go to a charcoal canister which i heard you dont need, but i just went to a junkyard and got one for 5 bux and hooked it up to the missing lines.. i checked all the lines on the IM and everythings there - no leaks. yet im still getting a code 3

i dont think the wires are bad because they worked on my previous swap.

i start my car and there is no code until like 6 seconds later. im running SUPER rich, like 13 mpg...
