Hi all

So brought a project few weeks back hopefully not one I will regret.... My first dip into the world of 90's built like a tank Mercs, after owning a GL, so this is only my second Benz and my first to get my hands dirty on...:confused:

engine harness:
I believe she needs a new engine harness part of it has been replaced, injector cables look new. However after checking some other cables I noticed they are deteriorating, after a quick look I believe they lead to the MAF sensor and throttle body, didn't want to disturb them too much, till I have a solution, which I guess is paying the stealer A LOT of £££££££, last resort!!!!!
So sourcing one from somewhere or getting one made up??

Engine surge:
After along trip i noticed the engine was surging when idling so while I was admiring the V12 I thought I'd clean the MAF sensors no luck, I guess next step will be look for any vacuum leaks, anything else i should be looking for??

Wheels..
Even though this has been one of my dream cars. After looking at it for a few days I come to the conclusion I don't like the way she sits.
It needs bigger and wider wheels. Ideally getting the wheels flush with the fenders. I know a lot of you would suggest keep it stock and enjoy the ride, it's just my preference.. any advice on sizes would be great.

GRILL
IT NEEDS A NEW GRILL, CAN'T SEEM TO FIND ONE ANYWHERE!!!

Any and every help would be great.

Thanks

Uneven idle is often air leaks into the inlet manifold or split/disconnected pipes that connect to it.

Try unplugging (and marking!) all of them and plug the open ports to see if things improve.

To get the look sorted talk to Sileck in Kent.
They refurbished my 129 harness and also the throttle body harness and it runs far better now.
You'll need to remove the harness and send it to them and they return it in a couple, of weeks (well they did mine).
