![]() My problem is this I just recently had an emmisions test on my 88 Mustang. It failed for CO%, limit was 1.01 the car blew a 2.12, it also failed for HC ppm, limit on that was 180 it blew 256. I checked the EGR valve to see if maybe it wasn't working properly, it's fine no problem found. The cats on the car are original they have 174,000 miles on them.
This is the main problem I was messing around with the timing and set it at 16 degrees. I't pinged it *** off, so I tried 14,it still pinged it *** off. So I tried 10 whitch is a factory setting it still pinged. So right now it set at about 4-5 degrees, now it doesn't ping whitch is good. But because of the fact it is set so low it runs like a dog not a horse what the HELL is going on. Next step is new stock converters, new 02 sensors,and I'm going to do an induction service on it to blow out some of the carbon that is probably built up in it. My stang is just running really rich. Oh also I did put new cap rotor and plugs on it. Please any suggestions would really help. Thanks, Justin |
