2g gst wideband reads lean help needed

[mikey1990]

Hello guys I have a quick question to ask even though I should already know if it is my o2 sensor or not but I have changed out my 850cc to 1200cc injectors and now my car is running like crap. The guy told me that 1 of the 1200cc injectors is clog and is only working at like 70 perfect but I'm not sure if that would cause my wideband to read lean ---, I also tried the brake cleaner method with the o2 while its still hooked up to the wideband, I had my car on to see if it'll go rich on my wideband while I had some brake cleaner on a rag but it didn't budge at all but stayed lean --- any help would be appreciated thanks, also all connections have been checked and they are good.

Sounds to me like your Wideband O2 sensor is shot. Same thing happened to me

You have one 1200cc in injector running at 70%, essentially 840cc. Could that be a problem? Sure. I'd get that injector cleaned by FIC or a similar company ASAP.

Yank the wideband and recalibrate it. If it doesn't fix the issue, replace the sensor.

Have you double checked to make sure the 1200cc injectors are seated properly or tried going back to your 850cc injectors?
