Runs for mins when cold then starts and then stalls repeatedly
Ok experienced m119ers
My E420 starts up when cold.
High idle about 1400 rpm
Fan clutch running on full (new acm)
Aux fans running slow.
Then stalls after about 3 or 4 minutes when reaches around 80 degrees C.
Start car again but stalls after a few seconds. Stalls in a sharp manner. As if some critical item shutoff.
This shutoff only started after replacing the spark plugs. I installed the normal recommended Bosch plugs.
Ive tried diff base module, two other LH. My T LLR module seems to have a damaged solder joint that I resoldered. Not sure what TLllR module failure symptoms are.
All vaccum hoses replaced a few month ago. I will do more testing on sunday again.
Installed a new o2 sensor a couple months ago but I was not happy with the 4 wire connections I had to make for it. I will be installing the o2 sensor with the correct connector
Any ideas with this gents?
