Exclamation marks are in lieu of more colorful symbols...
I bought my second '88 and this time it's supercharged. Go me, right? wrong.
The previous owner advertised "New JDM Motor 63k mi." Well, said I, sounds great. Never crossed my mind that the jdm motor has no egr and can't be smogged. Came with an old smog cert and everything...
Anyway, short of doing what he did, (getting a mechanic to write "pass" on the egr line) how can I fix this problem (and lower NOX which is just over the limit).
P.S. A mechanic told me I might be able to fix the emissions by advancing the timing a little, but there's still the lack of an egr valve. And i apologize if you've seen this question before, I'm sort of pressed for time and couldn't comb through the whole board but an hour of searching hasn't turned up anything useful.
