Thanks Clyons and steveinfrance. I have just given up and taken it to a shop were its been for two days. They did lower gaskets and upper and rid me of lean codes so far.

Now I think I am having a case a serious bad luck. My jag does not love me. I took her to the shop giving all codes listed above. Thinking P0301 was causing code p1313. Now the mech told me he never changed coil one with a new coil. He change coil 2 with coil 1. Now coil 1 and 2 are fine. But coil 3 is giving me code p0303 and causing p1313. What is going on. I keep replacing coils one at a time but this is just wierd. The Mech says its the computer giving bad relay to injectors but I read that if it was the computer than all injectors would be messing up. I dont know what to do now. My jag is my only vehicle in a state that i know no one. What is this problem?

 

Well to anyone wanting to know how I resolved this issue I had for a year I had to have Upper AND Lower Intake Gaskets Replaced with all three back coils. Worked Perfect for 2 days then 2 codes for cat failure appered. Doesnt shake or anything anymore so I feel happy. Will replace with new cats becuase I drove with misfires and leaking intake for a whole year so I think they need to be replaced. Other than that this problem is fixed. Thanks for all those that did contribute.
