Hi all. No dought all the good guys on here willl have come across this problem before. I've been to the garage & the say the fault is an EGR valve so I've replaced that. Guess what, its wores!! If its in top (auto) your coasting @ 30- 40- 50- etc, then raise the revs slightly, eg: to past something, then it becomes lumpy again......Doh...

hi there
when you're in at the coil packs, take the spark plugs out and check the gap is correct. also check that they were in nice and tight, as they can work loose.

Check the wiring to/from the EDIS unit - ( hides under the screen washer bottle offside front wing ) - there are 11 wires. I dont know (yet) what they all do but the likely culprit could be the black / white which controls the voltage stabilisation of the fuel pump through the ECU
Let us know
