They do. But anyway, you access the spark plugs from the wheel well.

(I forgot to swap the coil pack so I'll do that here tonight or tomorrow morning and update)

Changed the plug. I put a new cheap autolight double platinum.

She still coughs. Less coughing, but quite bad. Actually throws the car around quite a bit. I don't think it's derivable out of second gear.
New codes...
P0300
P0304
P0305
P0306

Please advise. Any and all suggestions are greatly appreciated.

I have the nicest little blonde that I can call the moment this car is derivable. And no, I can't show up in a rental.

Maybe its bad fuel,check fuel filter for moisture.??

All misfire codes on the same bank.
P0300 is a general misfire code that is telling you the misfires are strong enough to damage the Cat.
the other three codes are the individual cylinders on the same bank.

So you have an issue that is affecting one bank only.
So not a fuel problem
not a vacuum leak
most likely not 3 bad plugs all at once. although it could happen.
most likely not 3 bad coils all at once . although it could happen.

possibly an electrical problem in the wiring to the fuel injectors for that bank

you need to look for something that would affect all three cylinders on that one bank.
But doesn't affect the other bank.

In your first post you mentioned a metallic rattle.
There could be internal problems on that bank with the cam timing.
You Could have a failed variocam actuator or failed actuator pad.
or chain tensioner issues. I think they have a wear pad as well but not positive.
any of the cam chain issues mentioned can create slack in the chain and throw cam timing off creating misfires.
A compression test on that bank may tell you if your cam timing is off.
A leak down test would be better.

The O2 sensor code in your first post is telling you (if I am reading things correctly. I mess up sometimes)
that DME is not getting a signal from the O2 sensor.

P1121 is your throttle position sensor
could be a shot sensor.
could be a problem with the wiring to the sensor.

The P117 code in your first post?
Sorry I believe all OBDII codes are 4 digit. But I could be wrong!!!
So I have no info on that one.

Thank you Blue62 for the thoughts. I appreciate your knowledge.

Logically, it seemed like bad fuel. Mechanically this car has run perfect. Like new and has been babied.

The odd part is the sudden change in performance the moment the new fuel was added.

Gonna swap the coil and see whats up - will update here in a bit.

Since you now have codes for all 3 cyl on bank 2, swapping a coil on the same side will not prove anything. You'll need to swap it to bank 1 for an effective test. Clean up the plug you took out and put it back in the original cyl you took it out of. It sounds like you just threw a random spark plug into your car and that's not good.

Bad gas would not selectively choose to foul just bank 2 cyls.

You da man Husker. Thank you. I thought about this when swapped 4 to 6 - the coil.

So an hour ago I swap the coil from 4 to 6 and she is worse. Same condition as the original but now the check engine light flashes continuously.

Using Touque Lite I have no current codes driving around the block twice.

Pending Codes are...

P1319
P1318
P1316
P1317

In that order.

I will clean up the original plug back in. It looks good. I plan to put all new premium plugs in due time.

I will swap the coil to the other side in an hour or so.

I have Torque Light and Scan Master Pro is not connecting. Are there other features to this app to help diagnose the issue?

There is a possibility - very small that I put the wrong gas in. That pump has 3 handles... 6 buttons and it's hot as hell. I even checked the receipt, and I'm fairly certain I bought premium. It's worth noting. If it was easy, i would drain every drop of fuel to eliminate that possibility.

Kindly - check out this link... https://www.renntech.org/topic/32676-p1316-p1317-p1318-p1319/

This guy changed the MAF, the air intake tube looked loose on the throttle body. After wriggling it around he found it to be disconnected. Should I clean the MAF and inspect the air intake tube on the throttle body?

"... an access door...".

"... cheap autolight double platinum..."

"... has been babied".

That doesn't reconcile. You say the car has been babied... yet you don't know how to access the spark plugs? The car hasn't been babied if you don't know how to reach its heart (engine).

Cheap autolite...? There's a difference between cheap and inexpensive. You don't go cheap with a baby.

You say you will "investigate". You might consider doing some reading... get to know your car better. I would recommend The 101 Projects book (that will be a big help, and will mitigate the "mystery" of our cars. Also... pick up the service manual.)

Finally... read every new post that pops up in this, the best, 986 forum. So many wise minds are resident here. In a year you'll be upon these pages answering newbie questions Yup).

Pics. Post pics.

Ummm... Starter Bro I bought the car 5 thousand miles ago. I get laid. I also learned that criticizing is a great way to alienate people. Something tells me you haven't read How to Win Friends and Influence people. Respectfully, I'm too busy keeping the really hot women of Palm Beach happy to read every post. I'd rather ask an expert and not reinvent the wheel.

I'm hoping the wit and wisdom of other men that actually get pussy will help me out... and some divine intervention would be appreciated as well.
