by any chance, would unbolting your muffler make your car run rich?

Mike_C

no. your muffler has nothing to do with your air/fuel ratio. do you know how an engine works?

Man i came into this thread looking for a serious question because im running rich as hell and would have liked to fix this problem before i go turbo. And then i see this **** and its like "what the ****!?!?"

Im jacking this thread just a little, If you get an adjustible FPR would that help you to smooth it out without losing hp or would you ahve to go to a dyno to have it work right?

wouldnt u gain horsepower if u ran a little leaner but more chance of hurting your motor?

Running very rich will reduce power and kill your gas milage. It is probably a leaky injector. Your exhaust has nothing to do with you running rich. You can get an adjustable FPR but if your injectors are leaking, it wont help. Fix your problems before you go turbo or try to add another part to fix something else that is broken.

I am also running rich and want to know the easiest way to fix it.

All of the people who are running rich, have you checked your O2 sensors lately? Because if it is not working it will tell the PCM to richen the fuel mixture.

JDMlyfestyle

its better to run rich than to run lean imo. bad gas mileage with rich or u could detonate while running too lean

It is definately much better to run rich. Running too lean causes your engine to burn way too hot and can cause a lot of damage.

i am actually running very lean right now because i have a turbo on my ls and i am not runing the fuel pump nor the fmu....and that is alot worst then runnin rich...but before turbo i was runnin rich because my o2 scensor that is supposed to be hooked up to my exaust manifold wasnt hooked up....and for the people who use the Autometer or any other brand air to fuel ratio gauge....best believe that its probably not reading accurate. most of those are bullshit best way is to get a compression test and put ur car on the machine they call ob2...which checks for every little flaw on ur motor

bravo..bravo.. this thread started out pretty useless..but it has done almost a 180....nice..i learned a little somethin at the end..hehe!

Luserkid

Is there any test to be able to see if it is leaky injectors? Cause that might be it because i know my 02 sensor is working fine (atleast i believe it is)

well if ur injector is leaking just turn on the car and see if theres fuel leaking from your injector if that is the case then just change ur injector seals 8 bucks for 1 injector seal kit.

Where would i see it leaking? On the IM? Cause i dont see any leaks.

Could changing the timing have anything to do with it maybe?

92jdmhatch

you would see your leaks from the injector on the intake manifold and it will smell like gas big time...but....changing ur timing has nothing to do with it....thats for sure

North_Texas

How could you tell or know that your 02 sensor is fucked. Engine light coming on? Mine doesn't just asking, cause I'm also running rich but just wanted to stop wasting so much gas. But I kind of like the whole blk smoke look when coming out of the muffler.

not to sure how you would check your o2 scensor too see if its working properly but about the white smoke....sometimes theres white smoke coming out of ur muffler due to bent valves soo id get those checked out...once again compression test or tear apart your head

I think when somebody mentioned "leaky injector" they were talking the internals are leaking. Not the seal. An injector is nothing more than a sloenoid valve essentially. It opens and closes. That's the clicking you hear when the car is running. When one gets stuck open it leaks fuel constantly. And at around 40 psi at idle that can pump out quite a bit of fuel. This would make that one cylinder run rich.
I think that's what the guy was saying when he said leaky injector. A leaky injector seal wouldn't make your car run rich.

Please stop talking.
First offf would you like to explain how white smoke is caused by bent valves? Because I think it is caused by coolant burning. I also think that I am right.

If your 02 is crapping out, you'll get a CEL. May come on after warming up a bit.

Shut up now.

If you were running very lean on a turbo setup my guess is that you would not be running.

How in the hell is a compression test going to give you an air/fuel number.

And this "machine" that they call ob2? WTF are you babbling? Do you mean On Board Diagnostics 2?

It is required by law that on any OBD2 car turn on the CEL whenever emissions are 1.5 times normal. Just thought I would throw that little piece of info out there.

i agree w/ the white smoke being the coolant and or water burning not a bent valve..
