Hey everyone I'm kinda new to the forum but have used it to solve my Throttle body problem, just wanted to thank all u guys who posted threads on this, after removing the TB and cleaning it and all the connectors the kitty is purring once more not sure for how long but so far so good

 

Well yesterday I removed the throttle body wasnt going to be happy until i did ,cleaned it with crc tb cleaner, spayed and cleaned all connectors with crc electronic cleaner and put it all back cleaned the grounds under the left side fuse box and slowly pressed the pedal up and down for a five count three times, remove the negative battery cable touched it to the positive waited 20 seconds and put it back on let car idle for 10 min then drove a couple of blocks in normal and sport, nothing yet but have not gone far still would like to know how to follow these wires

 

curious, what errors if any did your car throw when the TB went koo koo?

 

I was getting 0121,1367,1111 and failsafe mode,asc trac not found, limp home mode it was coming every couple of miles, then more and more

 

The P0121 code is addressed by Jaguar on a TSB for your year car. It seems that the Throttle Body electrical plugs were not compatible and need to be replaced. In most cases it can be cured by cleaning and a tight fit. You can clean it by using CRC contact cleaner and check that they are tight fit. I also use a little CRC Di-electric grease to eliminate moisture and other elements. Go to this link to see the plug and the process TBoddy I hope this helps!
