Lethal may want to try to sell you you need to have it retuned or your tune looked at but slow 02 response is not a tune issue its a sensor issue.

That code means that the 02 on the right bank in the front is reacting slowly to changes made by the ecu to the air fuel mixture during the ecus o2 sensor test cycle.

you need to replace the bank 2 front 02 sensor and inspect the wires to it to make sure they are in good condition.

if you ever want to look up obd2 codes just go to OBD-II Trouble Codes - OBD-II DTC Trouble Codes Repair Help Site

And the p1000 is normal for any ford vehicle with a custom tune if you have the rear 02s turned off wich we did for you because of your busted cats however it doesnt cause a check engine light its the other code that is lighting your cel.

That code is simply telling you that the obd-2 self test on the rear 02s did not complete nothing more. < because we turned them off >

Your cats are also dying.. i told you that when you were on the dyno.

Remember the roten egg smell for the first few few pulls on the dyno ?


Remember it was 18-1 at cruise when it came in its around 14.5 now wich is right where you should be.

well put, i was just about to jump in about the p1000... that's nothing but a readiness code... however dean, i thought when you turned them off, it just completely shut them off?? i've never had a car w/ disabled o2's throw a p1000 that i recall... my honest guess is that some of the other sensors aren't ready yet... i'd run a readiness check on it, MAC tools sells a little tiny obd2 tool for like $80 that pulls readiness status and codes and clears codes...
