I need help!!! I have a 1994 3.4l v6 camaro and something is missing for example when i accl normally ill get to about 50 and then it willl miss all the way until i get to 55mph, i need a new driveshaft, i could prob go for a new engine because im pushing over 200k miles, and i would like to give it some more horsepower. I could use some advice.

 

Welcome to the forum. You're right 200K is really getting up there. Try cleaning the injectors first.
