those running gutted cats or testpipes with non foulers. what setup are you exactly running?
Since there are different kinds of non foulers:
Short 18mm ones and Long 18mm ones. The short ones wont even accept the 02 sensor unless those are drilled out. The long foulers will accept the 02 sensor to a certain extend but wont thread all the way into the fouler.
Question now is: how are your foulers stacked?
SN = short fouler non drilled
SD = short fouler drilled
LN = long fouler non drilled
LD = long fouler drilled
02 = 02 sensor
TP = testpipe
code = errors saved
cel = Check engine light illuminated
also state your year and engine code
02 | LD | SN | testpipe | 00 atw = CEL
02 | LD | 00 atw = CEL
02 | LN | 00 atw = CEL
this would be my response as of today
02 | TP | 00 atw = CEL

02 | LN | LD | Testpipe 00 ATW code=CEL every 200-300 miles
The CEL is sporadic and will go away after 50 or so miles of driving with it on. However my friend who also has a DBW car-but a 2001 does not get a CEL and has the exact same setup.
