Question about Cars & Trucks

1 Answer

Lacking power I had the black death. One injector was leaking. A mechanic cleaned the injector compartment and pulled out the injectors, he told me they looked like new. The copper washers and bolts were replaced. After that repair my van has been lacking power. I cleaned the MAF sensor which was clogged. Not much difference. Now all cars, other vans and some trucks overtake me on long uphills with overtaking lane. My speed slows down to 50 km/h and I need to change down to 3th gear. Some occasional smoking from the exhaust. It used to get up the hills without slowing down much, perhaps 90 km/h on steeper straight hills. What should I try, I can not afford to take it to Mercedes dealer who charge heaps but try to tackle the problem myself. Showed it to my friend who is a MB mechanic but because of Xmas and had to travel I could not get it fixed. The diagnodtics showed no faults!

I had an Isuzu that had a faulty air sensor that caused a similar problem. When my check engine light would come on the car ran like new, because it would compinsate for the error message. But for the first 6 months of the problem the computer was not recieving an error when there actually was one. The problem is it could be anyone of dozens of sensors starting on combustion and ending at the last exhaust sensor. I would start by checking the connections on anything touched when the service work was done. If the problem is similar to mine you will also notice that your (mpg/kpg) fuel efficiency has decreased with the loss of power.

SOURCE: 1.5 diesel megane injection fault

The cheapest way to go is to change the fuel filters first and the air filter. Then I would change the crankshaft sensor.

You may have to bit the bullet , and have the fuel pump changed before the fuel injection pump. The fuel pump in the tank can be loosing pressure to the fuel injectoin pump.
I think the lesser cost is the fuel tank pump vs. the fuel injection pump.

The system runs of fuel and air. No spark like on a gas engine.

So the problem can only be lack of fuel or lack of air getting into the vehicle air induction. A restriction in fuel or air will make the engine run poorly.
