You plugged the injector into the cam actuator connector... We've had others do the same unfortunately, pretty cut and dry. Its burns them up.

That was the first injector. I then had to replace the injector you sent me with a 3rd injector

i can't see the image, you have to upload it first. if you are having a misfire on a single cylinder, i'd swap a plug to another cylinder (1-3) and the plug around (1-2) and see where the misfire follows first.

Dude, that's a bot that stole one of your own posts.

I've been reporting them left and right too! 4 posts always and they steal from early posts and link to crap. If you clicked on one of those links AV scan the hell out of your computer as they're likely attempting an exploit :-(

update on PO 205
I just went through a similar issue. Even though the symptoms might not be identical to yours. In 2013 I had a RUF issue phisically "worked on" by a US Tuner in order to accept said Tuner's 91 octane tune and injectors. The car ran fine for a while and then PO205 landed, accompanied at times with various misfire codes PO300, PO304 PO305. I had the injector # 5 replaced with a new one. Car ran fine for a while, 3K + miles and then the fault code cycle started again. Wiring resistance from the DME plug to the injector # 5 plug checked OK, so did the "old new" injector. I must add, that for the nearly four years I ran the car on the RUF ecu, I had never seen a PO205 code. After talking it over with a local P mechanic who had had an instance of a GT2 a few years back with similar symptoms, I finally purchased a new DME, had the dealer code it and low and behold after downloading the tune onto the new unmolested ECU, the car has been running fine with no more codes. Early days since I have less than 20 miles worth of driving. I will drive the car all week, 100 + miles and report back next weekend.
Hope this helps.
Hope this helps.
The car has been running well now since early January, after another round of diagnostics at a P dealership. It turns out the culprit was the proverbial $5 adapter that goes in between the 72 lbs injectors and the stock wiring harness. This is the second instance of a bad adapter witch develops an intermittent fault after a few thousand miles. I am now prepared for another round of this ****. I will then replace all six connectors with $20
adapters which should last four times as long... I hope!

It turns out that the brand new ECU only ran for 5 days and less than 1000 miles before the PO 205 code resurfaced.

Bringing this thread back to life. I recently got a P0301 Cyl1 misfire. Coils and plugs replaced about 25,000 miles ago but since have done some mods incl tune. I'm going to start w/ plugs and COPs. Question: for a tuned 996TT what is the best plug and COP? I've read varying suggestions. Thank you.
