Hi all, I have just joined up, my first post is in the hope someone can give me some direction in finding a mis-fire in my series 1 ss. Here is the run down
driving home this morning from work and with only 40km left in the tank I accelerated around a corner and experiancde what I thought was a lean out due to low fuel, car dropped power ect, but had a missfire that didnt go away, filled up with fuel , no change, pulled the injector plugs one at a time and found no.6 not firing. so I have:
swapped plugs over, no change
swapped leads over, no change
swapped coils over, no change
swapped injectors over, no change
compression tested cylinder, over 150psi, (tested another and that was the same)
I have been thinking possibility of being a fuel pump down on pressure? the missfire is constant, doesnt dissapear ect, and seems like its even dropping more as load increases? Power is down, but probably more than one cylinder would have done I thought. I will check the pressure tommorrow, but can anyone else think of a cause I could look for? engine has 130000k now, and gets driving a bit spirited most of the time:surprise:, but when it started to miss I wouldn't have been over 5000rpm, any thoughts? cheers
