alright guys im posting again. i should be getting the car fixed within the next few weeks but i have a few questions. i just charge the A.C. in my car and when i turn it on the car stumble is 5 times worse. the rpms move all over the place when i have my foot on the brake. what the car is doing is when it warms up i get a bad stumble that starts around 2 thousand rpms. what do you think i should fix first then.\

its a 94 z28 auto.
