[adamm306]

Need a bit of advice... problem seems to of developed today (yay lucky me)

car struggles to idle atall even when adjusting the pump even to 1100 will sit at 1100 for 5 seconds or so then drop down to 500 to the point where it going to cut out (sometimes does cut out) then raises back up and does that

or if im poodling about and change down to second to turn a corner itll cut out in mid corner

oh and an occasional missfire when driving lol..

car has been running sweet till now it just started doing it this morning

any ideas
