I have an 84 4runner that I converted to EFI with parts all off of an 87 4runner. There is no place on my 22r engine block (that I can see) to put a knock sensor. Is not having a knock sensor hooked up going to make my 4runner fail smog when I bring it to a smog ref? Also my power steering pump doesn't have vacumn attachments (since it's an 84), right now the vacumn lines are just blocked off. Also I have a header that doesn't appear to have a CARB sticker on it, but it does have an O2 port, It was on the vehicle when i bought it. Do you guys think a smog ref will fail it because of either of these also? Any other suggestions or advise would be really appreciated, i have an appointment to go see the smog ref on wednesday....

sonds like yor in for a hurtin. the actall reff looks at everything! jiMMy

the Knock sensor.....is a maybe, some would some would not,
The P/S pump, no that has nothign to do with the smog, only on their to help the engine run smoother
The header, yes you need a CARB #, call who ever made that header and have them send you a sticker for it
