85 with a miss

hello everyone im going to be picking up and 85 n/a supra but it was postedsaying has miss fire but runs and drives if anyone knows what it could be any help will be awesome thanks

Hard to say without more info. It could be something simple like plugs, wires, dist cap, or rotor. You will just have to look it over.

I would agree with tcma on that one as well, try changin those things out and if that still doesn't work you might have to bite the bullet and go up to the dealership to run a diagnostic on it for more help.

Spray are around the injectors with carb. cleaner if leaking air the engine will immediately smooth out. As the previous post stated plugs and wires, and dist cap. are a problem area. I had better luck with denso plugs. Bad compression will also cause rough idle. You have to go to napa and purchase an oring seal kit. Use vasoline for lube when installing.
