hello, I just cant figure it out. I am still having a hesitation problem with the check engine light immulating for a quick second while the car hesitates and then goes away. The car will also stall once in a while. I have cleaned the throttle body, changed the MAF to a new one. Put in a new TPS Switch, a new fuel pump, cleaned out the intake, and checked for vacumm leaks and found nothing! I do not know where to look next. I still have no codes! I took the car to a local european service sop that has the newest jaguar software and tps, and maf came up, but changed both of them and nothing! same issue. If someone can help me where to look next please! thanks.

 

I had similar symptoms after having new spark plugs installed by my mechanic.
after a month or so fooling around with TB, mafs etc I remembered a post in this forum and replaced the new plugs with the oriiginal type champions specified by Jaguar. you should find previous postings if you do a search under stalling... my problems went away instantly despite the disbelief of many experts!

 

thanks for the info, I have had my sparks done about 3-4 months ago, and the problem started about a month ago, so is that kind of long? and I used champions, just not sure which ones. Does it matter? thanks.

 

ML, have you checked the EGR valve, be sure to clean those holes good, mine was about half clogged up
