That's exactly why you should always be extra careful in choosing the right spark plugs for the engine.
Be prepared for 2 and 4.
Btw, I saw quite cheap China-made coils for renault on e-bay which compared to original might be more cost effective. Has anyone used such?
Thanks for both of your replies guys! So Matt Black, you think I should try this before just replacing all 4 of the coils to see if it works? The coil Packs I fitted to my last scenic were only 50 quid for the 4 and have been ok for 18 months now. The engine in this car is as you stated above a K4M - I may just fit the coil packs anyway for the price just for peace of mind in the future if thats what you both think it is. I just didn't want to splash out on a new coil pack only to relise it didn't fix the issue. Just one more question? If I continue to drive the car could it cause serious damage as I would have to wait a couple of days for the Coil pack to arrive and need to get to work (unfortunately there is no public transport to where I work!)There was a recall on pencil coils back in 2001. Renault fitted SAGEM units as standard but they were replaced by DENSO units.
They misfire in damp conditions. An easy fix is remove them, blow any moisture out of the plug hole. dry the coils off, remove the plugs and clean them up, refit the plugs, refit the coils squirting WD40 over them - this should repel any mositure and stop the engine misfiring.
They fitted these coil packs to all of these engines....
K4J - 1.4 16V
K4M - 1.6 16V
F4P - 1.8 16V
F4R - 2.0 16V
Glad you got it sorted and many thanks for the update. Time will tell if its permanent fix.I should also add that beforehand it didn't have a problem until the engine was warm but after doing the above I drove for quite a number of miles uphill downhill and slow and fast.
Well so far so good, I have not fitted the new coils as they have not arrived yet but the car has been fine not a murmur! Thanks for the tips guys. I have been using it to go to work in and have taken out the coil and spark plug that had the problem and checked and all seems dry and fine - I'll keep my eye on it and feed back if theres anything untoward. I'm gonna also keep the new coils as a spare set as I know as sson as I let them go I will have a coil fail!!!! Once again thanks ever so for all your time and effort - keep on rolling!!!!Glad you got it sorted and many thanks for the update. Time will tell if its permanent fix.
