Had a very nice day on Sunday at the NAD. Today, we had our annual Tube Strike in London and therefore had to drive to work. On my way back this afternoon the traffic was really bad and the temp rose above 90 degrees but stayed there. Later the car started to jerk and splutter when pulling away from traffic lights and won't rev above 3000rpm. As soon as I get near 3000 rpm it feels like a rev limiter kicking in. I need to replace the lambda, but before today it only idled rough and the injector light came on after a while. Are these latest simptoms still the lambda playing games or could it be something else.
