I have an 05 it is showing p0204 and p2149, this has been a reocurring problem since 11000 miles and no one can find the problem, ive had multiple trips to the shop where they have replaced the computer, injectors, and multiple sensors, they have also checked the wiring by the a/c sensor that has been mentioned many times here. Does anyone have any suggestions, im fed up with this being it has been going on for 2 years and 53000 miles, any help would be appreciated

 

lots of views, no replies, anybody???
