If I give it too much gas, it stutters and misfires. If I am light on the gas it seems to not act up as much. It does this under load, what I mean is that if it is idleing, and I depress the gas pedal, revving the engine, it doesn't happen. If I am getting onto the interstate, and I need to accelerate, I can not "floor it" as it will buck violently. Getting on the interstate has to be a gradual, slowly accelerating entrance.
Pulled the code. I forget what the code number was, but it said random misfire and also said vacuum leak.
I have tried the brake cleaner spray vacuum leak test with no results..... I have 75,000 miles and have never replace the plug or wires....
any thoughts?
