mk1 v6 first problem..misfire

[laverdamancouk]

hi all ..have not posted for a while due to having too much fun in the little go kart but last night the first problem ..
the car had been stood for about 2 days and started fine but after about 3 miles i noticed a different sound coming from the engine a little loss in power ...pulled over and a definate misfire was there.
AA came and plugged the old computer in and came back with a po300 random/multiple cylinder misfire detected.and the little gearbox light came on and off a few times...but he could not pinpoint it to an exact place...he said if it was a sensor it would have shown up.
the service at 24000 is due...but would rather look at this first before taking it in for that
but firstly has anyone ever had a similar problem to this....
my first point of call will be plug change just in case one or more are a little aged ...does everyone still use what was supplied from new or are there any better ones as a preference?
....i know the coil packs have a tendency to go is there any way of checking if one is dud?
how much are new ones if i find it to be the case...and are there any other types that are better than the original reno...
many thanks in anticipation of all your info .

coil pack is my bet, VERY common on the Vee

very very common (coil failure)
just hope its not one on the rear bank - cause inlet manifold will have to some off!!!

had coil prob on a 172 - but was damp and fine when dried out...maybe worth trying to eliminate before renault tells you it needs a new engine!

thanks guys....anyone had this done out of warranty and have a rough idea of the item cost ..just so i dont get ripped off...seems strange if two or more have gone down though...wondering if a cold day or two may have got some moisture around some terminals...
anyone have a place to look at a manual...
many thanks

Def coil pack matey... all are easy to replace apart from one that needs plenium off.. if warranty left or extended will be covered

yes defo coil pack, i replaced the one under the plenum myself and its a piece of piss just awkward, im a mechanical disaster zone as well..

£36 from renault for the coil, and about 20 mins if its one of the easy 3, about 3 hours for the back ones
