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
