that makes sense re blocked cat .
the connections to the egr valve are all sound..one clue, maybe a red herring; there is water coming out of exhaust pipe not much, steam really...had head reworked a year ago..wonder if water is getting into the fuel mix ? header tank needs a pint every 1000 miles

Too rich? PCM thinks engine is still cold?

sensors sending back right temp to ecu eg 196f ..fuel trims are high and lambda doesnt switch code on obd is 0171 lean...just odd that it runs so smoothly for first 5 mins

I think a big clue here is "header tank needs a pint every 1000 miles" and "water out of exhaust", does suggest coolant is leaking into a cylinder or intake somewhere (?)
