Ok I bought my 1994 GT stock a month ago. It now has 410 gears ac smog egr delete transgo shift kit msd cap rotor coil. I also replaced the plugs fuel and air filter.. Now I have a strange miss between 4-5k it almost completely stops. Also have a surging idle and when I put it in gear it almost wants to die. When its warmed up. Im going to change to 9mm plug wires. I checked fuel pressure idling it was at 36psi I dont know where these cars are supposed to be but I have to drop the tank to fix my float anyway. Any one had an issue like this? Thanks in advance!
