Failed the high speed HC Has to be below 220 parts per million. Mine ran at 1143.
Then took it to get evaluated for 100 bucks roughly and they say no. 3 isn't firing/ and is an internal engine problem and will probably need a new engine soon. Truck is missing but still runs strong. Any tips on getting it to pass for now? I heard something about methanol. Anyone tried this before?
 
Rebuild the engine or get new one. There is no way to pass the test with unburnt gas in the exhaust system The 02 sensor should had turn on check engine lite. It will not pass with that lite on. Also unburnt gas is going into you engine oil.
