i just got my 94 z about 3 days ago. it was fine the first day just cruisin around, but now when i get on the gas the car dosent accelerate smooth at all, it bucks and jumps just like when u r about to run out of gas. the car was sitting for about 6 months so i thought it could be bad gas, so i put in about $10 93 octane and i still have the same problem. im thinking maybe bad injector(s), spark plugs/wires maybe? if anybody could help me out that would be great, thanx.
