Had an issue where there was a leaking fuel pipe which caused the engine to stutter when idle. Tightening would allow ensure the idled at 900-1000rpm so when it went to the garage to have some bits done I had them replace the hose and clamps and it seemed to fix the issue (no fuel smell inside car and a steady idle) but now when the car pulls up at lights etc. and idles it dropping to 5-600 rpm, feels as though its about to stall and then corrects itself. I'm planning to give the car a service, check the plugs, fuel filter etc. just wondering what else I should check and if anyone has encountered this issue before?
its one of the square plugs at the back of the plenum near the battery, I think the connector is red, if you haven't replaced your loom its probably brown. http://z32.wikispaces.com/Idle+Control
