Just bought an 88 gt...absolutely mint.41,000 miles ..but sat in storage for 3 to 4 years. ..running rough and won't idle cause of bad gas...anyone know what I'm in for and what to suggest having done

drop tank, clean it out? If it was me, I would connect up a vac source (something like a hand pump extractor) and remove the gas via the fuel filter connection. Pour in new gas and run it. Now... this doesn't mean you are out of the clear, as you may have gunk in the tank, but I have had Fieros sit for a long time without issue. So... worse case, drop tank.... otherwise, pull out old gas and replace with new.

Probably more than just the gas.

Mine hasn't been driven since 1999. I fired it up last year and it ran fine. But then, I treated it with Sta-Bil.

Now my Pilot Vehicle is another story. That car sat in a barn, in crappy conditions for 15-20 years. It started then quit. Before I try to get it to run on its own, I'm going to drop the tank, clean it and flush the fuel system.

I suggest you do the same.

You ran w/ "bad gas" doesn't mean much... Any damage is likely done.

If low then just add more fresh fuel.
if full then empty most then fill w/ new.
Use a bottle of injector cleaner or "dry gas" can help w/ a full tank of fresh fuel. Run close to empty then repeat. (Fiero tank is small and using both in same fill-up can be bad.)

Replace fuel filter after running awhile. Fiero filters take allow of crap before plugging. Crap can come out of the tank after filling once or a few times.

Out of curious, where did you find this car? In Abington? Where's that?

I live in abington MA,... I drove to Pennsylvania to check it out and bought it...I just want to say thank you all for chiming in...as long as it's fixable I'm good ...this thing is absolutely mint

I'm not sure how to post a pic...I'm a new to this forum...but when I figure it out I'm sure you all will aprreciate the condition of this car...

If you're running Windows, use PIP which was designed for this site.

Three to 4 years isn't that long. I would probably just top if off with fresh fuel if it's less than half now. If it happens to be full then dropping the tank is your best option. My only advise there is do it from the side. Life the car on one side it will be a whole lot easier than trying to get the whole car up in the air.
