Thank you very much for your insight Bill.
Any suggestion on what my next step should be to resolve this?
As far as mechanical stuff goes I had a new front 02 sensor put in this summer, had my UP gaskets replaced, had a pressure test done at the inlet, had a compression test done (150 across all 4), spark plugs were checked and they had good coloring, 4 new DW 650 injectors installed as one had failed,...unrelated to this I also had my timing belt done.
I feel like I have checked everything mechanical at this point so should I contact a tuner to look at my map?
Is there anything I am leaving out?
Thx for all the help.
