^^Exactly. I'd change the plugs and dump in some Lucas Injector cleaner...and some higher octane gas...like higher than 92+. Then I'd take off the fuel rail and blow it out with an air gun if you can and see if anything comes out of it...eg. buildup...then replace your injector O-Rings...they are like $5 or less. Also...since the fuel rail is aluminum...check to see if it is bent...as that happens VERY easily and there might not be an injector seating just right. That...could then lead to a fuel AND vacuum leak...like I had...the bracket that bolted the fuel rail to the LIM was bent a little...once bent back...fixed everything right up.
