Looking for a little advice.
A friend 08 E70 was running rough, cel flashing. Felt like it was misfiring.
Using INPA diagnosed that there was a repeated misfire on cylinder #1.
Original plugs and coil packs fitted.
Advised him to order a set of replacement plugs and coil packs. Would help him install.
He ordered a set of Bosh coil packs from Amazon and NGK plugs as per the site’s recommendations.
We replaced the plugs , originals were not in the best condition (80K) Gaps looked at least 0.100
Replaced the coil packs and started it up.
Sounded smooth and was able to remove the CEL.
He drives away and not 20' turns around and says it's running bad again.
Scan it and now a misfire on Cylinder #6 [IMG]file:///C:/Users/ranner/AppData/Local/Temp/msohtmlclip1/01/clip_image001.gif[/IMG]
I'm at a loss. Any advice appreciated.
