I purchased an 84 190e for 700 dollars and it had some major stalling issues
i replaced
plugs
wires
cap rotor
injectors
idle control valve
fuel pressure regulator
airflow sesor
distributor
oxygen sensor
and it seems that it is still stalling and sometimes lacks power and backfires
could be the timing although i just fired yesterday in 6 months

where are the timing marks i look at the crankshaft and i can see the pointer . am i supposed to line that pointer up directly on crank mark or should it be a little off

Did you do a fuel pressure test? The backfiring is an indication of a lean mixture.

Did I mention somewhere else that 190Es stall as a normal operating condition?

Why did you change the accumulator?? and are these parts new?

Check the direction of the flow, there is also a check valve in the end of the fuel pump, might want to remove that and clean it, or replace it

no these parts are not new, i checked the fuel pump i couldnt hear it kick on from the bottom of the car, so i am suspecting it is the pump, the filter can only go on one way due to the banjo fitting on one end

Replace the fuel filter, with the pump, cheap insurance. also make sure the relay is in working order, buy making sure the pump has 12v going to it.

thanks for the advice, i was also tinkering around trying to find the crankcase sensor because when i was timing my car it didnt seem to time properly so i took off the bolts on the sensor on the crankshaft towrds thr right, about 1 oclock on the crankshaft and i pulled it and it literally cracked in half..so after trying to ream the old part out i decided to buy a new one hope it will take care of the stalling issue i usually get my parts on ebay swap them out and if i dont see a significant improvement relist them so im not getting nickel and dime to death , anmd sometimes make a few bucks

An aging 190E can be a temperamental bitch at times, for sure. I've had my 93 190E 2.3 8V for a little over 4 years. I love the car, but there are problem areas with these cars. I just got through replacing all the rubber hoses associated with the idle air circuit - you should check these out on yours if you didn't replace them when you replaced the IACV. The old lines on mine were hard as a rock and cracked when I took them off to clean my IACV. I was surprised how many little air leaks there were, and my idle is rock steady at 750rpm now.

I swap back and forth between driving the 190E and my 83 300D. I like the 190E the most when things are right with it, but the 300D is the best backup car a person could want - mine is relatively low mileage (under 200K) and will start with a single cycle of the glow plugs on even the coldest Memphis, TN day.

The 560 SEL is in a class of its own. Not even newer cars should be compared to it or that would be unfair to them.:D
Of all the cars I had (including Porsche, Ferrari... oh and a 600SEL) I can say without hesitation that 560SEL is the best in many ways that I can't even begin to list them.
