Greetings to all experts,
Well, I am new to group & MB, I got a MB 260 (6 cylinders 2.6 Liter engine) automatic model 91, with 130K KM odometer. Basically this MB came from Germany to a hot climate (Environment).
I replaced most of the filters and oil seals before I start using.
The following problems are noticed:
1.) Less gas consumption only 6KM per liter @ 120 KMPH, what is the actual mileage supposes to give?2.) Black smoke layer forms at exhaust (end of the silencer pipes) no smoke visible.
3.) In Economy mode engine stop at signals, standard mode no engine stopping.4.) Fuel indicator after middle of the tank it vibrates (up & down) not stable.
5.) Some times long start (time).6.) When I start early morning there will be tick, tick... sound for a while.
When I show to mechanic he said all these indication leads (needed) to replace fuel injectors, I replaced 6 injector's nozzles and rubbers but the consumption remains same 6 KMPL. Long start problem seems to reduced, how do I know the old injector are good/bad?
I shown to other mechanic he is telling me to replace fuel distributor (repair kit).
I shown to another mechanic he suggested me to replace/cut the heat boosters in the exhaust tube (silencer), according to him in German environment need heat (temp) holder some kind of ceramic conduction material which holds the temp. all your comments & advices highly appreciated. Thanks in Advance
