hi i have a 1995 chevy 1500 with a 4.3 v6 TBI i wont pass smog,
my tast results for HC (ppm) MAX-100 MEAS-337 at idle
CO% MAX-1.10 MEAS-1.28 at 2485 rpms
i dont know what would cause this and i have know idea were to start so any help on getting it to pass smog in Ca would be really appreciated
i was thinking maybe my EGR valve or pcv Valve of do i check to see if there bad of cloged? i was also wondering what would cause the inside of my TBI to be oily and wen i turn off the truck it smokes out of the tbi i can olny see if the the filter off tho thanks
