Also, is there a fuel injector diy? Didn't find one on the w203 board!

Edit: 145 for an injector. Can't I run a few more bottles of techron through? I swear, I've never heard of injectors going out at 65k, and I think you've told me before that it's quite rare!

Lane - I have never seen one in my time on the board. I'll have a look but I don't have the WIS loaded at present.

PM Karo for an R&R on injectors for the M112

Karo - HELP

Would techron be of any use anymore? I ran both tanks of suggested techron treated fuel before I changed my fuel filter..

lol, I'm discreetly trying to edge my way out of replacing an injector. Sounds like no fun.

Lane - you can try two more tanks with Techron but I think we are flogging a dead horse

An injector is not hard to replace - wait for Karo to post R&R - I have put out a call for him.

Then you can see whether a DIY worries you. We can help you through it - you are handy with these things.

I have not checked cost - Will have a look on RMeuropean etc.

Sorry - missed this - one page back. I think that the misfire triggers a semi limp mode.

Injector remove/install

Lane,

Attached are the WIS documents for removing the fuel rail and injectors.

Doesn't look too difficult. Injectors hardest part is usually getting them out because the O-rings almost seem to fuse themselves in place.

I see that an injector costs between $56 & $108 depending on whether you want Bosch. As you would only be doing one I would buy the cheapest. It will probably outlast the other 5.

I see that there is also a termination repair kit. I wonder if you have a bad connection on that injector - you should check it. The kit is only 10 bucks

Thanks John - I've been terribly off topic on this thread must concentrate! - Had to stop Matt's V6 bashing - blame him

I have all the wrong hobbies - cars/mbworld/motorsport, audio, women, photograhy, wine!

Could you switch and injector around with another to eliminate them that way no money spent just time?

Trey - good thought - you could as long as you put new O rings on the injectors. As John says you sometimes have to be a bit rough with them getting them out. lane can try this but I would hate him to end up with 2 damaged injectors. I don't mind if he damages no 4. I would say try this if the injectors choose to come out easily. If not forget it.

That does not seem terribly hard! I'd rather just get the cheaper one since you said it'd outlast my other ones. Is removing the fuel rail from the engine block along with all the injectors the hard part, or removing the injector from the fuel rail the hard part?

How long will my original injectors last?

Right, but after the engine is restarted, the semi limp mode should be gone. I'm getting a slight shake at idle. Wasn't there before the first misfire after new plugs.

Removing all the injectors is the hard part if they stick in the holes - If they don't it's dead easy. Benz has changed the "clamping" arrangement on the rail a few times - don't know which you have. I've seen this done 2 ways & mechanics that do it regularly make it all look so easy. I've seen the rail removed from all the injectors & then one injector pulled & I have seen all injectors pulled together with the rail as recommended in the method John posted. See which works easiest on your car. If in doubt stick to the Benz method. I think they just take it forgranted that you will change all injectors which is crazy. It's going to depend on the connection to the rail.

Bosch test injector cycles out to the equivalent of about 250,000 miles. I've seen injectors last twice that & I've seen failures before that. Injectors go a long way these days if fuel is clean.

lane - I don't know why it does this. I'm hoping with a couple of restarts it will improve.
