Volkswagen Repair: 2001 VW Jetta VR6 CEL Flashing, malfunction indicator light, coolant temp

Question
I was having a problem with my check CELT coming on and once in a while flashing. I took it to a VW dealer and they gave me the codes for an ignition coil and a coolant temp sensor.  I replaced both problems myself but still have the CELT doing the same thing.  I took it to another import dealer and now I have misfire codes for all cylinders and some new codes of p1176 O2 B1 limit attained.  What does this translate to?  I also got a 1296 pending code.  I have reduced power and my fuel consumption is considerable.  Any ideas of what to do next or what these codes are actually telling me to replace would be appreciated.  I no longer have the ignition coil codes come up or the coolant temp sensor just these new ones.

Answer
Hi Pete;
The catalytic converter is no longer capable of burning hydrocarbons after they escape the combustion chambers via the down pipes.  The catalytic converter requires replacement.  It also occurs to me that whoever replaced the plugs, and/or coils on your car did not use silicone dialectic material to shield the bottom ends of the coils from "bleeding" spark voltage into the cylinder head.  There is also a reflash for the ECM available at the Volkswagen dealer for these engines.  In the model year of your car the engine code is "AFP."
I do not know what a CELT is.  Different terminology according to who is teaching the concept, but it all boils down to the same stuff overall, I guess.  You've got a check engine light on.  Where I work, we just call it an MIL.  "Malfunction indicator light."
My first suggestion to make this problem go away permanently is to get the reflash of the computer, and then change all 6 coils, and your plugs at the same time.  Big expense, I know, but they aren't working right.  The other thing that has to be done is to replace the cat. like I said above.  I would suggest saving the money necessary to do it all at once, or you run the risk of contaminating the cat. before the rest of the ignition problem is fixed.  I realize this is a big expense, but without the ability to get my own hands on the car to see for sure which thing is causing what first, I don't know what else to recommend to eliminate this problem.
Good Luck, Pete.  I hope this helps.
