I've been having some problems lately with the usual #3 injector misfire on hot starts common to 2000 model year XJs with the 4.0. It usually manifests itself when starting the vehicle warm and takes a minute or so of lumpy idling to clear. Checked with the dealer today, and the prescribed debris shield fix was performed sometime in 2002 to alleviate the problem. So, my questions:
- Apart from the foil heat shield placed on top of the manifold, were any other changes made as part of the TSB?
- Heat soak while the vehicle is parked seems to be the issue. Anyone tried heat wrap on the fuel rail and/or injectors to fight the problem? If so, was it at all successful?
This is a fairly minor thing, but it's starting to drive me up the wall. Any help would be appreciated - I've checkd through some of the older threads, but most advise having the TSB performed, not what to do if the TSB work isn't holding.
