I guess I can check the engine ground.

is it possible that its something more along the lines of a fuel injector, or even spark problem?

2.5-12 · #19 10-16-2011, 11:30 PM

also, is that K40 in the back left of the engine compartment? any way to check its condition before ordering a replacement?

I ordered a fuel rail and injectors out of desperation.

2.5-12 · #27 11-22-2011, 05:11 PM

got my replacement AMG Bosch III EV6s with rail late last week, here are some pictures fresh out of my ultrasonic cleaning session. new baskets, spacers, top and bottom o rings and top & bottom spacers on order. fingers crossed hard this works.

2.5-12 · #28 11-28-2011, 07:12 PM

well, a little update here. got the rebuild kits.

pulled the old filter baskets out of the injectors

popped in the new ones with some effort

then replaced all the o rings, and pintle caps

voila, a nice and clean set of AMG EV6 greenies! cant wait to try em out.

Keep us posted. If it doesn't work, I recommend a compression check next to help isolate what's going on with cyls 2 and 3.

it was fuel injectors.

pulled the car out of storage, running like a dump, swapped in my used but rebuilt EV6 greenies and she fired right up, purrs like a large growly cat.

all fixed.
fuel injectors took a dump at 105k miles for those reading this thread in the future with a similar set of problems!
