After dealing with a ton of no-start, misfire, and excessive rich conditions, I believe my passenger side catalytic converter is done for.
My 05 Expedition EB 5.4L 3V 4x4 takes some time to start. It cranks for a good 5 seconds when cold starting and has a rough idle in drive gears and reverse. It seems to be fine (or at least a whole lot better) in park and neutral.
A little recent history - Originally had a misfire and gave codes P0302 and P2196. Replaced fuel filter, air filter, cleaned throttle body,and replaced plug/coil, car wouldn't start (only click). Replaced the starter with no success on starting. Removed the belt, cranked engine manually, car finally started but very slowly and painfully. Puffed a bunch of white smoke and smelled bad of raw fuel. After playing around with some stuff and taking to the dealer, they discovered codes P2196, P2198, and P0113. I replaced the MAF sensor and both B1S1 and B2S1 O2 sensors. Now the only code I had was the P2196. Took back to the dealership who confirmed a misfire still exists in cylinder 2 at low RPMs (misfire appeared to stabilize at higher RPMs). Got back home, replaced the new plug in cylinder 2 with a Motorcraft plug and coil (the originial ones I replaced with were not Motorcraft, I've learned my lesson). Fuel smell went away completely, but rough idle and hard start still exist.
I took it out for a drive last night and checked the cats when I got back. The passenger side (bank 1) was glowing inside. I believe this was a result of the misfire I fought with, but I can't be sure the problem is compeltely gone until the cat is replaced. As far as I understand, a plugged cat can cause these rough conditions.
Anyone have any suggestions on cat replacement? really just looking for a universal that can be welded in place if at all possible. I don't know exactly know which ones I should be looking at buying. I think it needs an O2 sensor port on the top.
Any suggestions welcome.
Thank you.
