87' Ram 50 emission problems
Hello all, I just bought this truck and i'm trying to get emissions passed so I can register and tag the car.
my Carbon monoxide and hydrocarbons are both high.
took it to a few places and they replaced the o2 sensors and cat but its still not helping i guess.
Numbers from emissions:
Hydrocarbons: 8.75 (suppose to be no higher than 3.00)
Carbon Monoxide 150.88 (suppose to be no higher than 25.00)
and I failed the pressure test. possible leak on fuel tank?
I have done a little research. maybe its the erg valve?
