Richard, Thanks for the advice. I will look into that LubriMoly Ventil Sauber for future reference

I was going to change the oil after my next tank in anycase as I was going to run another full tank of gas to make sure I get all the techron used up.

I also want to make sure I wont be ordering some parts if need be like a fuel filter. once I'm going to get all greasy working on the car, I might as well fix some other stuff while I am in there. hehe

On another note, be warned that old electrical tape will destroy leather. I had my radio out for some rewiring, and My friend was he,lping me. he touched the steering wheel with some of the tape residue on his hands, and the steering wheel literally got eaten like acid was on it. now instead of a smooth leather wheel, I have a rough all torn up one. He himself has never seen that happen in all his years using electrical tape. We think there must have been some kind of chemical reaction to the oil form my hands or something. I literally had chunks of clack leather coming of in my hands.

I was forced to use some hand cleaner and wd40 to remove the goo so I could drive the car. After that was all done I used some cleaner and it is now dry at least and not sticky and coming off in my hands.

I think it was strange as I had contemplated buying a steering wheel leather cover because my wheel had some wear on it, and that same day my rim on my wheel got messed up.

Go to Wall-Mart and get a cn of Berrymans B-12. Follow directions and see how she does. It might run a bit crappy for that tank but it will clean anything. sound like you might have a bad injector(s).

It could very well be an injector, you never know, but the car runs perfect and gets no drop in gas mileage, and idles smooth,a nd no fuel can be smelled, which would be a sign of a leaking injector or something.

I think it has either something to do with startup enrichment, for warm starts. Cold starting is better, but warm starting is tough, and seems to be getting tougher.

At first it appeared to have worked with cleaner, but I still have no improvement now after a couple of days of it being better. Its weird, its not a consistant thing.

This leads me to thinkt he ovp might be the culprit as this sounds like one of the symptoms of the ovp from other reading I ahev done.

Alon

I'm going to talk to my mech about it and see what he says.

I second the motion by Rdetoy. Techron used to be stocked at the local MBZ dealers in Southern California years ago. It is undoubtedly effective stuff. So is the Ventil Sauber; it is excellent. They are probably the only two truly effective (gasoline) injection cleaners on the market; they are not snake oil.

Problem was that some brain surgeons thought that if one can of techron is good, then two or three is better. Or they would add it at every fill up. Wrong move. The techron would ‘wash away’ the oil from the cylinder bores (actually it didn’t physically remove it per se, it broke down the oil film and thus made it ineffective. Mercedes ended up eating quite a few engines on warranty because of its misuse, and Presto - no more Techron at the dealers.

Definitely change your oil after running through the Techron. I always use a bottle of techron or vetil sauber in the tank of gas used prior to the next oil change on my gas engined babies.

I decided to check the OVP after reading about how the fuse fixed Donna's problem with her 300E. Some of her symptoms seemed similar to mine.I pulled the OVP fuse, and reseated it, car seems to start easier now and idle smoother and a tad higher than before.

What do you guys think?

I have not had a chance to test it after a good amount of driving or any driving yet, but I will later today... hehe

My fuse looked virtually new but taking it out and reseating it might be all it needed.

I'll keep you all posted.

You might need to replace the unit. Maybe you should take it out, clean it and then reseat the whole unit and see what happens

Gasoline

This has been an excellent discussion, and I would guess we've all learned a lot. I'd like to add one more note: Be sure to avoid getting gasoline at a station when the tanker truck is filling the station's underground tanks. When the station tanks are being filled, the gunk in the bottom of the tanks is stirred up, and if you're drawing your gasoline at the same time, you're likely to wind up with some of the gunk in your automobile tank. It happened to me ONCE. Never again. Happy motoring, everybody.

Ashman,

You mentioned fuses and it is worthwhile to note that if the fuses in your car are original, then they are 10 years old. It costs next to nothing to buy a replacement set, and it takes next to no time to remove old/replace new and clean the contacts with contact cleaner. Not only does this increase the reliability of your electrical system, it can *cure* some otherwise incurable problems. It is a quick, easy and very worthwhile thing to do.

Regards,

The first thing I did when I got my car was to replace every fuse in the fuse box with new ones.

The problem varies from day to day, its very strange.

Yesterday it was very hard to start the car. Today it has been much easier to start it, and that is since I messedwith the fuse ont he OVP. I did not change the OVP fuse, I merely took it out and reseated it.

Last night after I did that, the car started up instantly,a nd idled a bit higher.

Today the car is not starting instantly, but it is starting much much better than the day before.

I suspect that this is an OVP issue. The car is getting the same gas mileage, there is no fuel smell anywhere near the fuel injection and there is no dripping fuel. Spark is good, fuel is the right kind, oil is fresh, engine idles smooth as can be, and does not stall or idle rough. The only problem is cold start and warm starting, which are both about the same, it seems to make no difference when hot or cold.

Generally I can get it fired up then it dies, then I try again, and it cranks a bit and then starts. After this it runs fine btu still has the hard starting.

Should I go ahead and replace the ovp as a precation?

I'm actually calling my mech now to ask him, but I want to hear from all my friends here as well.

Alon

I have a '72 280SE 4.5 that basically has the same problem. I've just about done everything to try and find the culprit, but have been unable to. After 6 months, 3 different mechanics and some new parts I'm thinking of donating car to charity, but really would like to try and 'fix' it since it runs fantastic when it wants to. What is an OVP and does my car have one? Thanks!!

Alan,
Just change the OVP and get it over with! It's cheap, easy and likely a culprit. Even if it isn't, it's good preventative maintenance!

Mbztrio,
I don't think your car has one... The OVP is Overvolt Protection Relay, it protects the cars electrical system from getting fried, but can go faulty after a few years and cause all sorts of electrical problem. If you want to learn more, do a search, this topic has been discussed a MILLION times!

Good luck Alon and just change it.

Hello. "OVP" is a new one on me. (I'm a junior member.) Does my '84 380SE have one? If so, about how much would a new one cost? Can I replace it myself? I'm a great believer in preventative maintenance.

This is weird,

I just filled up at a different station than my usual one, this one is near my office. The gas price was low compared to my usual station, I needed gas, so I got gas, the car starts better now.

I have a feeling the gas stations are screwing with the gas, mixing it down or something.

I'm going to see how the car does tomorrow on this gas, if it is better, I'm going to geta hold of the owner of my usual station to complain...

I think I will change the OVP. I didn't get a chance to talk to my mech either, I got busy...

Alon
