Lumpy Idle - Denso plugs

[Chris Mac]

got the car serviced lately, including timing belt, aux belt, water pump

the idle seems to be abit more lumpy than before

the mechanic recommended Denso Irridium plugs, and he put them in

would this cause it to be lumpy and run worse than before??

dont think so mate, i got them in the meg and start up, idle seems fine.. just my 2p worth

Quite a few v6 owners have them and I've not heard of any complaints.

Did he use the proper tools for timing up the belts/cams?

What was the gap on the plugs before he fitted them?

Locking tools are important as so many have been timed up incorrectly before, although they usually feel slower when they have been.

Change them for the the proper NGK PFR6E-10s if you want to see if they make any difference.

yes all the correct renault tools were used

engine seems to be times correctly, its pulling from low revs
vvt comes in at the same point, and revs to the same point
