Hi all from DFW TX, just picked up a clean 82 280ZX with 126K, I could not get it to pass inspection too high of HC & CO. How here the deal pull all the plugs and only 2 was carboned filled, so I put new plugs & wires. It runs fine ( I think ) smooth and it don't smoke, could it be 2 injectors that is not operating correctly. I am in the process of running a threated tank of injector cleaner thru it whis week, I say I think because this is my first Z and the horse power is a little different, all my past restorations are Pontiac GTO's, so does this now make me a Ricer.
