Hi Guys,
Hopefully someone can tell me that my engine is not knackered!
I was driving up a long hill on the A55 with a car in front doing 70, when he pulled over I accelerated reasonably hard in fifth as there was a Merc up my chuff!
All of a sudden the check engine light starts flashing and there is a loss of power, accompanied by some smoke but I'm not sure if it is more than usual as she does drink a bit.
I pulled over into a layby with the engine running really rough and read the codes. P0301, misfire on cylinder 1. I limped to the next services as I didn't like the exposed layby and waited for the RAC man.
He swapped the coil packs and plugs around but the misfire stayed on 1. The plug for 1 did look rather manky with some hard light coloured deposits. 2 was better but still a bit light. He called it a day and arranged recovery from Wales back down to Kent!
Now I have her home, I tried swapping the injectors around between 1 & 2, the misfire stayed with 1.
Right now I am thinking something major is wrong internally, either head gasket, valves or rings. I'll be buying a compression tester tomorrow to see if that is a problem...
Any thoughts what it might be? Something else to look for? Any help, advice or abuse gratefully received!
Alex.
Edit:- Might be useful saying that she is a 1999 C70 T5 ME7.
