That's good news then. You must've righted something from your fiddling. Or the reset finally kicked in? Mysterious.

 

Well, I didn't have a single problem all last week. Every morning it fired right up without any issues. Then after it sat all weekend....I go to fire it up this morning, and it did the fire up then die thing again.

It's such a random issue...I think I'm just going to live with it until the problem either gets worse, or goes away. Not sure I want to start throwing money at it right now....especially when there are some many little things it could be.

 

Any further insight on the cause or resolution of this issue?
My 2005 MCS (JCW) is doing the exact same thing so I am following this thread closely.

 

It seems like it's so sporadic...it's really hard to figure out. Sometimes it will do it every morning......but for the last month it hasn't done it at all. Really hard to figure out when it's not consistent.

 

I recently took 400 mile road trip and noticed some intense stuttering when I let off the gas on the highway. When I pulled off the highway to get gas the car stuttered and shut off. I restarted the engine but the car would simply not idle. Given the remainder of my trip was going to filled with traffic I resorted to letting the car die out and simply restart it over and over everytime I needed to move again.

After much frustration I took the car to a Pepboys to have the codes read where the car put a P0108 code. After doing some research on the issue I decided to order a new TMAP sensor. The sensor came a few days later and in the process of waiting I took the existing TMAP sensor out of my car. I found that the old sensor after 115,000 miles was covered in oil. I cleaned the sensor and reinstalled it but no luck the sensor had sustained enough damage over the 115k that it needed to be replaced.

I got the new sensor in and put it in and voila no problems. I will post again if anything changes.

 

Hi Guys any update. My R53 is doing an identical thing so far
New battery
Camshaft sensor
Fuel pump and filter
Newish coil plugs and leads under 2 years old and under 6000miles

Any help? Thanks so much

 

Mine did it a few days in a row last month, but hasn't done it since. Before that, it's been close to a year since it did it last. Very weird.....like so many other quirks on these R53's.

 

Mine has done this a few times. I put it down to bad gas because is stopped after my next fill up. May just be a coincidence.
