Failed emissions
Hi all!
i am a proud owner of a v6 1995 Dak, however, the waterpump expired and it sat for about 4 or 5 months before i fixed it. even though it is fixed my inspection was up, and now i have failed emissions. my report says, under the HC ppm x liters, "limit- 537" "test value-635" FAIL. my CO and NO test were fine, im hoping i dont need a new cat converter, any suggestions?
thanks for your time. i have big plans for this truck and wanna keep it for a long long time

I would say check your fuel pressure/volume first. Next check the O2 sensor and probably replace it.

and there seems to be no real way of really narrowing it down. unfortunatly i will have to take the 70 dollar test again without knowing if the money i spent was still not enough, then i would need a new cat converter. i've also picked up a can of seafoam, figured it couldn't hurt...i hope. and my truck is having trouble shifting into 3rd! but i love it to much to let it go
