I have a 1994 Camaro LT1 that just suddenly started acting weird. I was leaving work a couple days ago on the highway, and my car started surging. Temps were fine, everything was noticeably okay, but it felt like it wanted to die. Well as soon as I pulled off the highway it died. I kept turning it over, giving it gas until finally it started back. Now everytime I drive it it does the same thing, feels like its giving out a little bit while at high speed, when I stop it dies. Any ideas??? Thank you!
