Hello, i just spent about 3 hours trying to change the spark plugs and wires on my 1999 3.8 v6 camaro and i only managed to change 3 before it got dark (yeah i took it slow lol). So when i go and start up my car just to see if it would start or not, it shook extremly bad. I was just wondering if its because i have 3 different kinds of plugs on one side and 3 of the old ones on the other. or did i mess up on the three that i installed?
