Right as of last night my R19 16v runabout shit box has started to missfire.

When started from cold it's fine will run fine, responsive etc, as soon as it's upto normal running temp it develops a slight miss, which then gets worse and worse and then it starts to kangaroo a bit and looses almost all acceleration, even if I hold foot flat to the floor it will miss right upto the limiter (i know this ain't the best thing to do, but I was seeing if it would pull through the miss, at first it will but after a while it won't just miss's constantly).

Just seems weird it only does it when upto normal running temp

any ideas ???


anyone ?

cheers
