02s are always at 390-410 no matter what i do. during normal driving and also at WOT. seeing 1-4 degrees of knock at WOT. i maxed out the injector with the chip and still no change. :confused::confused:

car is running great for normal driving. except at the gas station today after i topped it off i went to start it and had not fuel pressure. so i bypassed the second pump and got it running, then unplugged the second pump and it stayed running. now seems to be running fine again. :confused:

thanks!

Get a Denso from Autozone/Pepboys.

Fixed! Thanks men. Grabbed a Bosch and popped it in. The denzo was special order. Now I need to get a power logger.
