1987 300zx Turbo wont pass smog!!!
I have had my 1987 300zx Turbo for about 4yrs now. It had no prior problem passing the smog test(California). But this year I took it to a smog check station and it failed with flying colors. Does anyone have any suggestions to what could be the problem(s). Anything will help thank you.

try doing a full tune up, and finding a way to clean out carbon build up in your engine, however the Z31's do it. mabye your cat started rusting out? i dotn know, just some basic suggestions from me.

Oh no, you had good ideas. I was just letting him know that if he can let us know how he failed then we can narrow it down for him instead him having to try everything possible. A tune up and what not is probably a good idea anyways if it's been a while
