[EliteV6]

Hiya, I was driving home earlier and the engine management flashed a few times then stayed on, i switched off then it was clear, when doing the flash test i have:

P0300 Random/multiple cylinder misfire detected
P0303 Cylinder 3 Misfire Detected
P0304 Cylinder 4 Misfire Detected
P0305 Cylinder 5 Misfire Detected

Since then I have driven locally a bit and the light only comes on and flashes when I really drive it hard, it is fine if I take it steady.

Searching seems this could be linked to a few things namely air leak, oil prob or dis packs/spark plugs etc?

Does this sound about right and which locations are the cylinders on the V6 engine, assuming as I have cylinders 3,4 and 5 that these are on both sides of the engine or am I incorrect?

Thanks

check for oil in the spark plug wells...

as tunnie says, pull the coil packs out, both sides, you may well have to remove plenum and cable tray on pass side and check
1. For oil in plug wells from leaking cam covers, caused by blocked breathers.
2, split rubber plugs
3, splits and cracks on the plastic around the 3 iron coars at the base(square ish bit with brass colour showing through) or anyware for that matter.
Any damage they need changeing.
4 damaged or old plugs, if youve gone that far you may as well change them anyway. Vx on trade club is best deal afaik.
1.2.5 drivers side 2.4.6 pass side you may find easiest way to remove coil packs is to find the correct size bolt to screw into the brass bolt hole and pull on the bolt. Carefull tho they can stick and fly out wacking something on the way and possibly causing damage. Hth.

Thats what I done first time when changing DIS packs the week before last, but was able to do last weekend when changing plugs without moving the plenum, you need to disconnect the switchover valve at the back tho, otherwise the DIS pack won't come out, cos the connecting plugs in the way .............oh and removing the cable tray, rather pain removin that
