Guys,
I have an EF XR-6 with 100,000 on the clock. A problem I have noticed for the last six months or so is after doing about 4,000ks after a service (done every 10,000) the vehicle seems to clog up, stutters on acceleration and intermittent rough idle.
I am not driving it much lately which could be the reason, anyone else having the same problems. The injectors were cleaned at the last service. Also what type of spark plugs are recommended for the six.

Thanks Pins.

Attn Pins :
Talk to the actual mechanic that did the work to find out what was actualy done.
Obtain any reports that were run eg, diagnostic checks.

I run the Eagle 10mm leads, they seem good, but I've found the NGK ZGR-6B11 are excellent, they are the recommended NGK XR6 plug, the biggest difference being the longer reach, I find they give faster start up, better economy, power, acceleration & response and they only cost @ $3 each !

Why dont you check what is in your car now against one of these NGK's ? Who knows your mechanic may have fitted the stnd plug by mistake.

Thanks for the response and the info re the spark plugs, NGK plugs will be fitted at the next service.

Cheers Pins.

Yeah, there seems to be some problem with the coil packs on EF's, regarding the voltage output, with a hot engine bay. I have tried Magnacore 8.8 Leads ($80 bucks), Split fire plugs ($16 EACH!!!), and standard NGK R Plugs for the XR6 (Cant remember the type). The magnacore leads made the most difference. The car before the lead change would stutter at 60kpmh, when flooring it, but with the lead change, and same plugs, the car went a lot better, The split fires made about as much improvement to the performance as the standrard NGK-R Plugs, and considering I can get 6 NGK's for the price of 1 splitfire, I will be replacing my plugs with NGK's from now on !!!
