widebnad reading

[Nikolay_Ruskov]

hi i want to ask what can cause high reading from my wideband?
When i am idle is showing me 11.1-11.3
And if i got a exhaust leak should show me that i am running lean ?

thats pretty rich, what are you tuning with and what injectors do you have? maybe the sensor is bad or something

 

[Nikolay_Ruskov]

with nothing yet..i got dsmlink and 1000cc but they are not on the car for now
I am with stock injectors and ecu ..the only things which i install for now are front mount intercooler 2.5 cat+ downpipe upper hard intercooler pipes greddy type s air filter basic things fp manifold...

check for a vacuum leak...do a BLT

You are correct, a boost leak or exhaust leak should make it read lean, not rich. Those are very rich numbers at idle. What kind of fuel pump do you have? Do you have an AFPR? Is so what is it set at? How does it read cruising? WOT?

 

[Nikolay_Ruskov]

I am with stock fuel pump and afpr.... cruising i didn't pay attention but i think when i am at full boost 9.6 or something like this.. Can the o2 sensor be bad?

 

[9!'clipseDOHC]

It could be bad. How long have you had it? If you've had it for a while are these rich readings new? What is your AFPR set at at base idle?

Mine idles around 16 to 17, cruises at 14 to 15, and WOT at around 11.

Where did you get that faceplate where you have the wideband? Looks pretty neat. Or is it just a simple piece of plastic?

i got the wideband used and maybe is old. i dont have the afpr i got the stock think solenoid i think that how is call..i have and afpr but i didnt installed yet because i am putting everything buy steps i want to make this think work correct and then will put something new because if i put everything at once when something is wrong it will be more hard to find out why...but when the car is stock at idle should be 14.7 right?and can bad spark plugs make this difference i am not sure the are bad but they got like 2 year and more maybe

Yes bad spark plugs could cause your wideband to read rich. Think about it, if all of the fuel in the combustion chamber isn't being burned then it will be going down the exhaust. I would replace them right away, they are very cheap. It could very easily also be a bad sensor since you got it used.

I see you are in San Antonio, are you going to the Texas Mitsubishi Shootout on Sunday? I'll be there.

those definetly dont look good. but ## plugs really dont look rich at all, really looking stoich. i would go with some bpr7es plugs best for our cars. i run them in my 2g and i had to turn my fuel up still to +24 to get my car to idle and afr at 14.7 to 15

I only got a real quick glance at your engine temp gauge, but it looks like it wasn't warmed up all the way. If you're not at operating temperatures then that explains it too.

With your mods I would reccomend the factory BPR6ES copper plugs. Get rid of those iridiums.

The Texas Mitsubishi Shootout is this Sunday at San Antonio Raceway in Marion, Texas.

run the bpr6es until your upgaded alot and running like 20 psi then get the bpr7es

I just get what you sayin ..
the plugs really dont look ritch..because i got one old head with bosh spark plugs and they was black..i test them and its the same reading ...so i gess is the o2 sensor
