CS, I am guessing you are in Cincinnati. We do not get smog checks here in Columbus. Do they verify anything on the stickers? I have a '91 C900 which had EGR. I took it off and installed a '92 ECU which does not have EGR. The thing is that the fender sticker states that it is supposed to have EGR, though. Just wondering if I will have problems when we get smog check here in Cowlumbus. I don't think my '97 9k will have a problem, but we will see. A failed smog check could also be from a bad DI cassette/plugs. Incomplete combustion. I know your '88 does not have that, but your '94 could have a weak one... Keep us posted on the '94 Regards, Keith P.s My dad is in Blue Ash with 2 9ks ('91 and '94) and an '04 9^5. cs wrote: > gee, are you in Ohio?
