running lean

[f22/k24]

Ok I have a 93 accord lx f22a1 and I did head gasket and t belt and fule pump and main realy and I put in a new air fuel sensor along with a a/f gauge and im running way lean and I don't like it if any one can help let me know I don't under stand why it is to the point I don't want to drive the car

Those A/F gauges are nothing but a useless light show. They're pretty much worthless. It's more likely that the gauge is crap, or you hooked it up wrong.

By "a/f sensor" I assume you mean you got a new oxygen sensor? If it's not a Denso or NTK/NGK sensor, then it is likely to be malfunctioning. Many autoparts stores will give you a Bosch sensor, and they almost NEVER work for our cars. They, too, are a waste of money. If you installed anything but Denso or NTK/NGK (same company, they can come branded either way), then I STRONGLY suggest replacing it yet again with one of those. www.rockauto.com has a very good price on the Denso sensor.

Check your spark plugs. If the tips are chalky white with black specs, then you're running super lean. Otherwise, it's probably fine.


Why did you post a poll about turbo? It has absolutely nothing to do with this thread, and if you think your engine isn't running properly, a turbo should be the LAST thing on your mind!

I really have to disable polls for noobs...

Poll

We should have a poll on disabling polls for noobs.

Anyways, as deev said those gages are not so accurate, plus if you are running a gage off of a narrow band o2 sensor you won't get good readings anyway.

Is there any other reason other then the gage that you think the engine is running lean.

Also just because I am curious, what is "lean". As in what afr are you seeing.

[deevergote]

Every crap narrowband gauge I've ever seen bounces around, and then it pegs full lean or full rich from time to time.


If the gauge is getting a reading from a crap sensor, like a Bosch, then it's definitely not reporting accurate information.

A/F gauge would only come in handy if your running a good turbo setup and your tuning is precise on the edge of performance. Or a heavy built N/A running a aggressive tune and e.t.c but you're not running either so don't see the reason to install the dam thing in the first place...

The unrelated turbo question made me laugh, yet you think your car is encountering a problem and you still manage to think ahead to install or start a turbo setup? Like I tell every single newcomer, if you maintain and built a N/A motor it the future it would always be easy to boost it than just going directly to boosting the shit out of it and blowing it in 100 miles.

Take it slow, and smooth. Slow is smooth and smooth is fast be patient my friend.

Ninja edit: your POLL makes no sense at all, I don't get it thats not a yes or no question bro

[WhiteShift]

i think this depend also of the brand of the air fuel gauge... with denso sensor and reputable brand for the gauge... i think you can be ok... not only get a light show.. but this still narrowband.. wideband is definitely more accurate..

[deevergote]

Funnier yet, the poll is asking which is the better option... when both options are cheap, ghetto solutions. I guess the poll does have a function... it shows us how serious this guy is about his car. Sounds to me like very little research has been done, he wants to spend as little money as possible, and he's distracted by gimmicks. I am eagerly awaiting the "I blew my motor" thread.


The narrowband o2 sensor really just sends an on/off signal. There's not enough info for a gauge to properly display any useful information. If it pegs to one extreme or the other, it's due to one of two things: a faulty connection, or a problem with the motor that is so serious that it's probably already majorly damaged by the time the gauge does its thing.

A wideband o2 sensor and an appropriate gauge are the only real way to go... and as said above, if you don't have an engine that needs that feedback, it's not all that useful.

The poll options don't make any sense.....
If we vote yes, does that mean ebay?

[deevergote]

I think the poll options are putting both of those shitty turbo options on the same level, and we are to tell him if he should budget-boost his seemingly ailing F22A.
