Well, according to Ale, there haven't been any members who've had a steady cel after installing the pre-cat deletes. I'm wondering now, if we did something wrong during the install. The defoulers are on both pre-cats, and we placed them on second o2 sensor locations. Now, someone mentioned stacking the two? Are they supposed to be stacked on top of one another one both cats? on one cat? Should we have received 4 defoulers? Help?

Yes, we reset the ecu, and this is the 3rd time the cel has come back on. Any hints would be helpful!

Car's at the dealer getting bolts torqued down to spec, along with a few other things...so I don't have access to the car NOW, but will later in the week. Thanks again ALL!

 

my cel came on about 20 min after my install checked it out on the code reader and it was the lower o2 banks on each delete, i cleared the codes by resetting the ecu and they never came back. Are you pulling both fuses to reset the ecu?
