SOURCE: how to fix high hc on 94 isuzu rodeo v6 3.2

Took me a couple of views to figure out what HC means.
You would need to know what the limit is for your area and what the exhaust is producing, then find out what the cause is.
It stands for unburned hydrocarbons which is supposed to be controlled by the O2 sensor among other things. Could be a sensor or the engine not getting up to normal temp.

94 Isuzu rodeo started to idle high


Vehicles tend to idle higher for two main reasons, as the temperature becomes colder, the engine must work harder to warm itself up so it idles higher to accomplish this faster. The second may be due to a vacuum leak in the engine. Any other symptoms?

I have a 94' Isuzu rodeo with a fast tap


alot of the 4clys had ajustable tappets that might need adjusting
V6 have tappets adjusted also but are shims on top of bucket over valve spring, this is hard to do as you may need to change shims to get correct valve clearances suggest dealer to do.
if the noise comes in and out while maintaining 1500-2000rpm when stationary it is possibly worn valve guides which is common on high km vehicle.(head repairs)
