quick question on smog...
I just took my 89 5.0 in to get smoged on Saturday and I failed do to my timing bracket was swung down(missing top bolt.fixed) everything else I pasted...now when I brought it back in today I failed because (NO/PPM). MEAS was 611 instead of 565... The 1st time it was 473.... Help. I thought I needed to get my car warmed up more. But that's my opinion. At 15 MPH that was.
