Personally, I think clearing the code (with a scan tool) would be quicker. Otherwise you're going to have to wait for the code to clear itself (could take several days) or if the battery is disconnected have to perform up to 5 drive cycles to get the monitor to flag itself as ready.

It's about half done, I got super sick for 3-4 months and my Heath is not the best right now. I have a huge back issue right now that has me sidelined. 4 herniated disks in my lower lumbar. And that's the good part ! My knee is failing agin so I just can't do much right now, I have a "Fake" knee , it's called a "TKR" (Total Knee Replacement) I've had 4 of them in one leg so far and for some god forsaken reason it wont heal correctly. I thought it was all good, but issues keep comming up.. So, not done yet, BUT it will get done one way or the other, it's a goal of mine to finish the front, and do the sides and rear, it will and up like no other for sure. .. Sucks I can't finish it right now...

My wife's Mustang had an issue with pin holes on the filler neck causing an evap code. I corrected the problem, about 2-3 days of regular driving, the car cleared the code itself. At that point, I did not worry about the problem any further.

I PROBLY would not have attempted to clear the code now, but I had already disconnected the battery overnight, so, it's a lil to late to not clear the code as of now. I am running the car for a bit and driving to see if the codes return. I'll post an update tonight, and tomorrow my wife takes it back to EMMISSIONS to see if it passes or not. If it does, it will be good for another 2-3 years.. Got my fingers crossed ...Mjclemm.

As stated in #7 you may have to run at least 5 cycles to set the catalyst monitor to ready state.
Good Luck!

i ran the car thru 10`15 cycles. All codes are clear still no CEL. I install the Spark Plug anti foulers and its working for now. My wife takes it in tomorrow for emmissions. Illl et ya all know what the outcome is. If it does fail again, Im just gonna order the PCM from ZZP, I wanted to get it anyway, so this just speeds up the process...lol.... See ya tomorrow.... Mjclemm....

Think positive - it will pass! I replaced my DP/Cat about a year ago and (so far) haven't had any CEL problems. Hopefully it doesn't set one in another 6 months. If it does though I have my anti-foulers prepped and ready to go. Testing around here is every other year and I just went through it last April so I have some time before having to worry about it. Good luck...and think positive!

i think it is just wiered i have a high flow cats on my mustang. as well as on my monte due to the bad miss fire that i had from the coils. i didnt fail emissions when i was in va but now i am fl. i never new that our monte's were that tempermental for some minor changes to the exaughst?
