i was going to my car after class and it started up kinda funny. i didn't think anything of if. but when i put the car into gear i noticed that the ses light was on :angry: on the drive home whenever i'd accelerate it kinda felt like my car was pulsating a little bit. it felt like this when i was at idle too. but when i was going a constant speed i didn't notice the pulsing. my a/f ratio gauge was going extremely fast too, faster than normal. when i got home i popped the hood and it seemed like the engine was shaking a little too much for just being in park. i drive a 99 gt with approx 65k miles. do you think this could be a misfire? me and a buddy of mine recently changed the plugs and wires, but that was around november/december. thanks in advance for the help.
