    Yeah, That ^^^^

    .......... and any air leak in the intake ducting at or after the MAF - or that dumb resonator spigot - WILL set MAF codes.

    I saw that butt plug setup the other day on moists pics just wondering if it's just a 2" PVC cap with stainless clamp?

    Yep. The one in the picture is actually a rubber pipe cap - $1.85 at Ace hardware, with clamp - but you need to fill it with a solid plug to keep it from collapsing - I now use a slightly domed PVC pipe cap painted semi-gloss black.

    Find a suitable machine screw to replace the rubber Torx bolt at the PCM cover.

    I used the PVC pipe cap on my daughters '04 SLS and it doesn't even need a clamp. I went with flat black and it almost looks OEM.

    IF you have not actually gone into the car's built in code system and manually "clear codes" it will take 3 start-run-drive cycles for the SES to extinguish IF there are no other emissions or powertrain performance faults/codes set.

    OK - I see you did clear codes. Something else is fishy.

    Ya quite odd perhaps I have a bad ECM? Is that possibly? I've since drove around the city and I haven't felt hesitation and it runs much quieter yet still a ses

    PCM's are pretty reliable, but anything can fail.
