Calling all GEARHEADS (vehicle emissions)
ok i have a 89 cutlass supreme with a 2.8 multi-port
the hydrocarbons (HC) are to high what on this car controls HC'* the limit is .800 grams per mile and my reading is 1.0349 grams per mile
its got a new O2 sensor,Egr Vavle,MAF,CAT, and NEW timing chian,TPS
Would the MAP have anything to do with it?,
it probbaly needs a tune-up but im stumped
BTW Its OBD1 so i doesnt throw a code
what are all the emission controled components on this car?
