Web hydrocarbon emissions are simply unburned fuel being pumped raw into the exhaust system. Low compression would likely be corrected for by a properly functioning fuel control system including an accurate maf reading. Web emissions are measured in parts per million, or ppm, and a higher release of hydrocarbons from a vehicle can cause a failed smog test. 3.4454 limit 20.0 pass co2 gpm: Web failed colorado nox emissions test o orrsh discussion starter · #1 · mar 22, 2014 hello, i just purchased a '95 xj cherokee, and failed emissions this morning.

High hc emissions indicate unburned fuel. Web also, since your 2nd fail was due to high co, that indicates a bad pcv valve. Replaced plugs, oil, cleaned all filters, filled with 93 octane gas before testing, installed tiurbotweak emissions chip, converter in place. They should also give you a piece of paper that will tell you what is wrong take that to an auto mechanic and ask his opinion Fouled plugs would result in much higher hc due to misfire. Web up to $15 cash back the knock sensor is fine. For example, in the state of california, the maximum hydrocarbon parts per million is 64 when the test is run at a simulated 15 miles.

Misfiring is the most likely culprit, and that can come from an ignition problem, or an internal engine. Carbon monoxide exceeding maximum limits, can be due to a number of emission failures. Car was in a shop for a 1 1/2 years in. While i'm on this, high hc can indicate a fault in the ignition system which includes spark plugs & wires, ign coil, & ign timing.
