DET runs rich

[SR20_N_KC]

I have had my swap for about a year and my cars seems to run really rich. You can really smell the fuel. I dont get horrible gas mileage. I have 3 inch exhaust with no cat and I am running witht the stock MASF. Any suggestions.

Look and see if your injectors aren't leaking. That could be dangerous.

check your coil packs and your spark plugs? to tell what may be going on, do a plug read to see if it's a leaky injector (one injector will have fuel on it) and won't read like a normally worn plug.

check it with a wideband(dyno) you may just be smelling fuel from removing the emissions stuff(if you have) or if it isn't working(if you haven't)

do you smell it inside the car?? Did you get a new fuel pump?I just got my sr running and i had the same problem. checked the fuel pump cover and realized the big O ring wasn't there. I need a new one too. I just used some create a gasket for now. seems to work pretty good. i don't think i can smell it anymore. i still run a little rich because of some backfire. i also don't have a cat back exhaust either!;) im just running off of the dp.

Thats cool. I checked the injectors last night. Nothing leaking. If I had to guess I would say it my exhaust. Damn that thing backfires something fierce and I dont smell fuel under the hood when the engine is reved up. I still need to check out my plugs and what not. It is time for a summer tune up anyways. Would getting a bigger MASF lean it out some?
