White smoke is usually coolant that went thru the cylinders,
such as a failed head gasket or other reasons
Could also be fuel- but that wouldn't be a continual visual
site when driving
STOP USING IT ---get it fixed Don't ruin a nice car
thanks but its not the head gasket , its the idle speed control or the (MAF) SENSOR how do i go about fixing them ?
Have a repair shop that knows Jaguars do the necessary testing Do not install parts yourself on a Wish & Hope Theory
ok, tanks.
No one can tell you what is wrong with any vehicle problem Only proper testing will do that When you say how do( I) go about something ,do you mean you personally make a repair This web site is full of people for have lots of secrets & share nothing with us, as to who does the work their asking about

The MAF is in the flex hose that delivers air to the engine, it has a 5 or 6 wire connector going to it.

I would lean toward the MAF sensor they were known for going bad, which would cause all these codes. It wouldn't hurt to take the IAC off and spray it out with carb cleaner and some WD40, just to cover your bases. Both these units were made by Bosch and the MAF failed alot more often then the IAC.

Here are the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.
To correct this problem I want you to get a can of intake cleaner (ABOUT $5.00) from any local auto parts store like NAPA or Carquest, do not use carburetor spray, intake cleaner only or u will damage the Teflon coating inside the throttle valve and air bypass valve, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
Testimonial: "Thank you, I'm sure if your advice it was I'm looking for. But at least if this works, it will save me a lot money from having to replace expensive sensors."
