check engine light
 

my check engine light came on while driving after I put in new injectors #1 oxygen content what do you think that means to rich to lean. settings are -41 to -37. what do you think

dang, i lost the link to the online code reader, i guess you will have to find out what cel you are getting and post it. :P

Re:check engine light
 

I reset it and it came back on; #1 oxygen content has anyone ever had that code before also if I hold it steady around 2000-2400 it surges it will rev and then die gaining and dropping 500 rpms.

Re:check engine light
 

it means you arent tuned properly....probably running too rich.

OR, you have a faulty O2 sensor

Re:check engine light
 

hondaswap.com has a list of the ecu error codes

Re:check engine light
 

any other ideas?

Re:check engine light
 

what injectors did you put in?

what ecu are you running?

Re:check engine light
 

make sure you o2 sensor cables are connected or if they came loose.

Re:check engine light
 

440 injectors stock 2000 si ecu, didnt do any thing with the o2 cables will check, also ping, death rattle (detionotion?) at full throttle in higer gears at lower rpms, using 94 octane gas,after I reset the ecu its fine until I start to rape it then the light comes on will come on in the lower rpms should I lean it out more -41 starting point for afc

Re:check engine light
 

So I don't suppose you've got a wideband? What is your timing set at? Are you retarding it at all?

Re:check engine light
 

still stock timing

obd2 sucks the biggest donkey dick, that's your problem right thurrrr

I hope you don't mind if I jump in on this thread...

I have an OBD0 hatch and don't get a CEL right away, but I eventually get one (Code 1) after driving on the highway for 10 or 15 minutes. I'm working on getting a new O2 sensor, but I starting wondering, "what if that's not the problem?" The car has absolutely no mods with 190,000 miles. But basically, I'm either running too rich, too lean or my sensor is going bad. Is that about right?

Re:check engine light
 

Most likely the sensor if you have no mods...

Re:check engine light
 

thats exacly what happens 10-15 miles after I reset the ecu cel comes back on with the code. So what do you thimk about when I hald the gas steady and it gaining and dropping rpms.everything was fine until I swaped injectors

Re:check engine light
 

so if the light doesn't come right back on when I reset the ecu could it be that the sensor is getting cloged up
