Sound sthe problems Ive had, I spoke to you recently regarding the inlet cam on a 98 C180. I did a head skim new MB gasket, reground all the valves after on cylinder was showing 50% compression loss, really bad misfire.
When the car came to me it could just about tickover but any selection of gears would stall the engine.
Anyway did the head skim, did the valves, put all back together and whilst trying to sort out the misfire it snapped the inlet camshaft, luckily at tickover.
did a compression test once new cam fiited and all cylinders good so no bent valves.
Replaced one faulty coil pack but found both to be cracked, anyway misfire gone, the C180 fires up and ticks over lovely. apply any throttle and the engine feels like its chocking. Drives well without harsh throttle but apply more throttle and it chokes.
Any ideas please before I drive it into a tree Jeremy Clarkson style.

) when I approached a road junction it stalled but started first turn of the key. Re checked the engine timing, one tooth out. It was after this that the cam snapped. Checked all vac lines and nothing untoward, checked the ovp replay and ok. Leads me to think that it is the fuel pressure control unit on the fuel rail that has stuck open. Feels like it is flooding when you start from stop. More noticeable when you pull up quickly and then accelerate. Variable timing is quite possible. All cleaned out and seems to be operating ok. Not 100% convinced though. ECU, Nope very much doubt it. as it starts first turn and purrs like the proverbial kitten on tickover. Acceleration is as it was before and kickdown is bang on. T feel that there may have been a flaw in the cam and my removing it to have the head skimmed may have been that step too far for it.
