ne advice would help...sorry for the noob questions..and also the transmission isnt working properly..you can hear and feel it go into gear but it wont drive in d and wont reverse in R..you can put it in R and push it forward and visa versa.

thanks again

 

Can you cover what you did - fixed?

By the list of codes I see something going on with the O2 Sensors, and causing the P03xx codes, but I'd like to follow your trail. These codes are a progression and likely all related to the same source problem.

 

havent had a chance 2 fix nething yet..she said she was driving down the hwy and the car just felt like it was in neutral..it wouldent engage in ne of the gears...and still wouldent..and i heard awhile back that if something major was wrong with the motor the transmission would do that..but im new to jag so thats why im here askin yall lol..and it kinda sounds like the catalytic converter may be clogged?

 

No, actually more like O2 sensors bad. At least those are the far easier parts to eliminate as the possible cause of the faults rather than the catalytic converters. Not saying those aren't the problems, but I'd start with O2 sensors.

This is assuming nothing crazy happened like someone filled the tank with diesel instead of gasoline...or any other foreign substances.

 

what do you think about the transmission?

 

and shes been useing just plain 87 unleaded octane instead of super unleaded so i didnt knw if that would cause the problem

 

I think the transmission is decoupling because the engine cannot maintain an expected torque. I don't believe there is any issue with the trans.

You should redirect your attention to fuel delivery. All of these P codes point to either a fuel delivery failure, or the O2 sensors have failed completely and can no longer feed the ECM to maintain a STFT. I'm thinking more now that the O2 sensors are reacting to the lack of fuel rather than causing the problem.

The X-Type uses a returnless fuel system. It maintains fuel pressure at the rail as long as the fuel pump is running. Start by checking fuel pressure at the rail move backwards to the filter, then to the pump.

 

okay i will check it out this weekend..you think this could be caused by her using just regular 87oct? shes been using 87 for YEARS apprently

 

Chrish,
Octain not the issue. Go with Stevetechs advice to get started. The boy has a great track record. Do let us know how it shakes out.

 

okay thanks..fuel pump is 4sure comin on, i think this weekend im gonna give it a tune up(air filter,plugs etc) and go from there..jaguar is alot different than my hondas lol

 

yes they are lol

 

ne more help? ne one in oklahoma on here who could possibly look at it?

 

nething?
