You can also use the search & type on your issues. Pretty common with these cars. Could be ignition coil or module, fuel pump, etc.
I would definitely do the spring cleaning list off of gnttype.org, & if the car doesn’t have them already a Scanmaster(at the least), a fuel pressure gauge, & Hotwire kit.
I would think if the car is running on E85 you may prolly have all those items.
