I am having difficulty passing my state mandated emission test on a 1990 Dodge Spirit with a 3.0 V-6 engine. I recently acquired this vehicle which has only 32K original miles on it. It was brought in from out of state where it had not been required to be tested for emissions.
The vehicle has obviously not been driven much but I have driven it for over
500 miles so the gasoline in it was fresh. The station that performed the emission testing suggested a tune up which I am in the process of doing before I bring it back for a re-test. About all that can be replaced during a tune up is plugs, dist. cap, rotor and plug wires. I am also running gum-out fuel injector cleaner through it and then a product from CRC which guarantees that you will pass the emission test or they'll refund double what you paid for it.I can't help but wonder if there isn't something else that I should to correct this problem once and for all since it will have to re-tested annually and with such low mileage I might have this vehicle for several years.
Any suggestions would be appreciated.
