Little GN guidance needed

[KCODE]

The problem: My car set about 5 months due to a broken forward drum in the trans. I would start it twice a month. I just fixed the trans and put it back in. Before sitting the car was running perfect. Now it has a very noticeable miss. I drove it today and when I got to 16# boost it back fired. Scanmaster readings look normal.
My plan is: run out old fuel, change fuel filter, wires and plugs. My question is am I barking up the right tree or could it be something else. I've also recently put in a new ECM with powerlogger.

I believe you are on the right track.

Thanks.

When you put the trans back in, are all the ground wires hooked back up?

If someone moved them to a trans bolt in the past, you might have left one hanging.

Would a bad ground cause it to run like I described?

A bad ground can make you want to soak the interior in diesel fuel and throw a match to it.

Make sure the ground is hooked up from the fire wall to bell housing on driver side.

Im thinking thats it b/c there was a spark under the car in that location.

My first thing I would do is get rid of 6 month old gas as pump gas starts to lose octane after only 3 weeks?

Probably the gas is ok until you get too much boost, in your case 16 psi is past way too much.

I keep 110 octane leaded race fuel in my low mileage and not often used turbo cars as this fuel will last a couple years!

what he said !!!!! helps not f up fuel pumps also

How much will this effect someone running ALKY?

Very good question, but I do not have an empirical answer?

Since gas has more octane than alky, I would surmise that it could have a dramatic affect after 6 months.
