Mercedes-Benz Weirdness

[bassmangrammy]

My car had been running rough and after a few shit-scary moments where when I was getting on the car, it lost most of it's power at like 5k RPM and then goes into safe mode. This has happened 5 or so times in the last 2 weeks.

So, today I take it to MAM to get new plugs and plug wires. Don't fix the problem, which I now know is a misfire. After the misfire, my car shuts down the cyclinder until the car is restarted.

So, logically, my tech thinks it's coil packs, so given they are close to $200 a piece and I have 8 of them, we swopped them around, but the misfires remained on the same cylinders.

So, it's probably the injectors. Right? As a result, I bought some techron injector cleaner and I'm running it through as I drive like a grandma.

Add to this, my "low tank pressure" indicator light has been coming on with some regularity.

What's the problem? Could it be a fuel filter? Fuel pump? or is it the injectors?

It's a Mercedes.

do you have an ignition control module? those crap out on the mercedes's retarded cousin, the audi, from time to time :lol:

stupid question...how tight is your gas cap on (low tank pressure what?)

[D_Eclipse9916]

to be honest it could be any of those...could even be a ripped o-ring at the fuel pump.

It does sound just like the two times Ive lost a coil pack in my car. I know you said you checked that out already, but it the symptoms are the same.

oh werd. Thanks.

I ordered a new fuel filter today... hopefully that fixes it.
