Hi,
I had my car dyno tuned the other day and it was running very well, with
good throttle response and a steady idle. Something has changed and it now
hunts or misfires a bit at idle (the engine seems to shake a bit more) and
at steady speeds the car surges and misfires slightly. If I accelerate from
a steady speed it misses for a bit, and then clears up and pulls strongly as
the revs rise.
Does this indicate a vacuum leak? I've concluded this as the misfire seems
to go away when the throttle is wide open causing the inlet manifold vacuum
to drop.
Any ideas/comments?
