hey guys,
i have a 95 pontiac grand prix with 3.1 engine.
this just started out of the blue,
problem
the car started to miss fire under load, like if you hold the brake and give it gas it will miss pretty bad like shake the car and you can hear it out the tail pipe. also it only dose this under load, once going its find untill (2nd problem) you hit 2nd gear and around about 3k rpm it will lose power, like you can feel and see it on the tach struggle to gain speed,it will gain speed but you can feel and see somthing is holding it back
i cant pull codes,never could. anyone got any tips or ideas?
