Question about 1997 Dodge Caravan
How fix ASM emission test HC(PPM) MAX 51-35MEAS 89-88 & NO (PPM) MAX 512-735MEAS 1136-1050
Have you got all your hoses running to the emmission control box (usually a round or rectangular box on the passenger side near firewall). Is the box old and needs replaceing? If you don't want to change because is very dear to do you could change your spark plugs and fuel filters? Also change your oil with a lighter oil a 55w/10 and oil filter and your spark plug leads with new ones 8mm diamiter would be good as it is less resistance for the spark which will aid in fuel burn and air filter change is good idea to, maybe 200 dollars or so to do this but all will help reduce your emmissions if emmission box isn't working properly. Hope this helps
