Start with the cheapest part first, new air filter, o2 sensor, egr valve, then if the problem still persists, consider a new catalytic converter. Probably around $125.00 to $160.00 at a reputable shop other than a dealer who could charge double!

Cylingone bad make it not pass emmisions test


No other option but to either replace engine, or have it rebuilt. And it can only be rebuilt if the block is good, which you won't really know untill you tear it all apart and inspect the bad cylinder.

My HC (PPM) WAS HIGH AND THE NO (PPM) WAS HIGH WHAT IS CAUSING THIS? SO I DID NOT PASS SMOG THANK YOU


An old worn out engine will have high emmisions due to burning oil. Also, with age, a catalitic converter won't burn up any fuel vapors causing high emmisions.

1987 bronco emmisions


that depends on what state you live in and what they require. i assume you must have to go a an old style drive on dynomometer ?. if so and the bronco is carberated. make sure you have at least 1 good converter .also make sure the fresh air smogg pump is working correctly. be sure the timming is not set too high as that will raise the hydrocarbons. than keep your fingers crossed.
good luck chris
