190e STalls when put in gear - PeachParts Mercedes-Benz Forum

I have gleened much help from this group and enjoy reading the postings regularly, especially the one about the OVP and why the car might run ok with a bad OVP and not run well with a good one. Thanks Stvebfl! That actually helped me a great deal! My 190e has not run in over 2 months, but this morning I made some adjustments and sealed a couple vacuum leaks and it runs. The car idels smooth and consistant at 800-900 in park. I am very happy with this, considering where I was a few months. my issue now is that when I put the car in drive or reverse, it stalls. This is everytime, unless I have the motor revving at 2000 or so, then it chirps the tires and goes. Given the following data, can anyone help me solve this problem? I have a completely rebuild head (new valves, cam, rockers, seals, guides). I have 152-155-153-152 compression. Timing is dead on and advance is working. New Bosch platinum plugs (I know.. get rid of em). New fuel filter and seemingly fine fuel pressure at the fuel distribution block. I also replaced all the fuel injector seals. Would an old cap and rotor cause this problem?

Somebody please help, it is a shame to see my car just sitting - especially when I am this close to having it perfect (I have a lot of other parts that are new also). Thanks guys!

My advice:

Take two bottles of Techron and call me in the morning!

Seriously ... try it.

You have only less than $20 to loose.

Have you cleaned the throttle body and idle control motor? These two items can definitely affect idle response.

The second bottle is in there now. I figured that I would try the miracle additive first. Thanks.

You haven't actually said whether you checked the OVP relay.

I have cleaned both the throttle body and the idle control motor to the best of my ability. As for testing the OVP, I have tested it to the extent that it can be tested out of the car... IE: there is voltage where there should be voltage according to a recent post on testing it. I am hoping to get the car running just well enough to get it to a pro to have it fixed right. I need to find someone good in my area, which is the Kingston/Poughkeepsie area of NY.

While your in there, take a look at the booster supply hose. On occasion they will seperate and the engine tourquing over will open up a decent sized vacum leak.

The booster supply hose? Where is that hose located? I think I have checked for most leaks, but I certainly will check again. Is there a vacuum connection between the tranny and the engine? I feel liek I am SO SO Close to finally fixing this car.

Latest update.. I started the car with no OVP and it runs like crap. Put OVP back in, smooths right out. Guess I can definitely rule out OVP.

I have another issue that might be adding to the stalling issue. When key is off I have a 1.7 amp draw on battery (even with NO fuses in). When car is running, voltage at battery measures 12.3 volts. Last night I wanted the car to idle for like 20 minutes.. about 15 minutes into the idling, the car dies. The battery was so dead at that point that even the dash lights would not come on. I am having the Alternator tested this evening. Hope I am on the right path. Makes me want to cry to see this car just sitting.

Pull the regulator and see if the brushs are worn out. Regulators are much cheaper than alternators. :-)

I took the alternator to the local parts shop (Autozone) to have it tested and it is putting out all of 6 to 8 volts. Haha I guess it is bad. I pulled the regulator (brushes). How do I tell if they are bad? Should I submit a picture here? My alternator is a 70amp Bosch. Perhaps someone could point me towards a 90amp or 120amp (I think the Volkswagen Corrado came with a 120amp Bosch). Can these more powerful alternators be fitted to my 190e?
