Some background, I have a 2011 with a BOE tune, headers, etc... I garage my car this fall with a full tank of Tier 1 fuel and never got around to adding gas stabilizer. A couple of weeks ago, I changed the oil and I finally drove it on Saturday. After about 30 minutes, I hard launched it and it ran great. As soon as I went back to cruising, it ran awful. A couple of miles down the road I got a P0302 (#2 misfire) and the corresponding P1302 for the cat with limp mode and the smell of old gas. Hoping that it was a coil problem, I swapped 2 with 4, reset the codes, and then drove it on Sunday with several restarts (since the TSM says 2 trips or more). It still ran like garbage, but I couldn't get the check engine light to light up again. At this point, I don't know if I need any troubleshooting help, but I am going to try to clean the throttle connection and I've siphoned out about 5 gallons of gas to try to get some fresh gas in there, but I keep thinking that if it's bad gas, I would get all the P030#'s. I probably can't get back to playing around with the car for a couple of weeks, but I'll update this when I do. I guess this post is just a heads up or therapy, lol. I guess I shouldn't have thought that I should sell it since I don't drive it, the car gods always get you.

I dunno, while that is a long layover, with a sealed system I would not think the gas would be unusable. I started a[non computerized] car with ~5 year old gas and it was fine.
I might not be right, but it ought to run

Coincidences are the bane of my automotive life.
Do these symptoms line up with the harness issues that vintage evora had?

That is a great question on the harness. I hope not!

If it might be harness, anyone have LSL636 by chance? It's FITMENT GUIDE-ENGINE HARNESS

I hate to say it, but my '11 Evora S with the BOE Chargecooler and headers (and tune) has been diagnosed with a blown engine on cylinders 2,4,6. Compression was 70, 120 50.

My shop is speculating a tune problem. Since the files are encoded, they're sending it to a guy who can open the ECU and look at it forensically.

Finally took a look this weekend. Cleaned the MAF and it's runs great. Really weird how the MAF causes a single cylinder misfire but doesn't set a check engine for the MAF. You would think you would get P0101-4.
I did purchase LSL636 and posted it to in the Evora How to Section -
Lotus Evora Docs - Service Notes, Owner's Manuals, etc...
