2007 STR Stalling

2007 STR Stalling
Our 07 STR has a continuing problem of randomly stalling when coasting at just over idle. Common areas for it to stall would be idling through a parking lot looking for a spot, coasting to a stoplight or in stop and go traffic on the freeway. The engine restarts immediately after it dies.
We have had 2 dealers look at the car (each 2 times). No codes and no check engine light. The dealers have re-flashed and upgraded the computer program twice. They also replaced 2 bad spark plugs and coils. The stalling still persists.
The dealers checked the fuel system and the engine electronics, but no problems found. Other than the stalling, the car runs great.
Any ideas on where the dealer should look next? Thank you.

Only thing that even comes remotely close that I can relate to is the earlier 4.0 xk8s used to have throttle body connector issues, and it would stall at steady highway speeds...either poor contact, or tin-gold pin mismatches, sometimes humidity/moisture can get into the TB connectors and cause problems too. The s-type guys can elaborate more on that issue...as I've only caught some statements here and there during moderator duties.

That happened to me twice already for some odd reason, I have 2007 STR also. as soon as I accelerate it turns off but just put in park and crank it up again with no problem.

I would check and make sure everything on the intake is sealed up. Make sure your filter is fit correctly and the box lid is closed properly. Make sure all the intake clamps are snug. I had something similar happen with a different car I had (not my S type) and it was cause the intake was loose and was throwing something off letting in the bad air and made it stall at idle.

Yes. The dealer replaced all the filters including fuel. There was also a problem with the thermostat that would not allow the engine to reach proper operating temperature. This was replaced along with leaking coolant reservoir tank. The dealer thought this might be the problem, but the car stalled again this last weekend.

We drove it all day today with no problems. Traffic, stoplights, you name it and not one hiccup. This is very odd.

In fact, I never feel it die. I'm idling along and then go to accelerate, but there is nothing there... No interruption in power to lights, stereo or dash.
Thanks for the help....

This is what Matt was talking about http://www.gusglikas.com/AutoRepTB.htm Not sure this is your problem but it is worth looking at. I did a little checking on alldata and it addresses a Drivability Issue/Stalling and it addresses grounding connections, mega fuses and fuse box power lead in the trunk near the battery and other fuse boxes and it goes on. I cannot suggest this is the problem with your 2007 because this TSB s 303-07 refers to 2000 to 2002 S-Type. This is another post you should read and compare notes https://www.jaguarforums.com/forum/s...ad.php?t=51216 I hope this helps!

Had the exact same problem on my 06 STR
I took my 06 STR into my dealer with the exact same symtpons a couple months ago. Their diagnosis was a bad catalitic converter (right side I think). Anyways they replaced it, free of charge, and I have not had the problem since then.

RE: Codes
joycesjag, Sorry but no. I remember my Jag dealer telling me over the phone the codes, however, since he said the fix was a freebie I wasn't really paying attention.
