I just bot a 91 legacy ej22t 4eat and the previos owner tried to put an ghetto ass intake on their. now all the car does is idle rough. any one know where to track some factory replacements besides the dealer?
im hoping this is whats causing it anyway. some of the lines were leaking and i tried to replace them and now they're kinking. gd getto riggers.
I may have what you need. Can you describe exactly what parts you're missing? There's the snorkus inside the fender, the bottom and top halves of the air filter box, the MAF sensor, and the pipe that goes from the MAF sensor to the throttle body.
If the rough idle is due to the intake, it is probably caused by a leak between the MAF sensor and the throttle body. You may want to try to find that leak and repair it if you do; that may fix the idle. You might try letting the engine idle and then spraying starter fluid around the intake tubing. If you spray near the leak, the engine will ingest some of the fluid and it will affect the idle speed.
