Q:

Why did my Jeep fail emissions? on 1995 Jeep Wrangler

'95 Jeep Wranger with 155,000 miles failed emissions due to to much HC GPM readings (3.3177 vs. the allowable 2.000). What could be the problem? Coming out of 1st gear, about 1/2 way through, there is a loss of power. Could this be a fuel injector or catalytic converter problem?

Improper ignition timing, defective ignition components, lean fuel mixture, defective catalytic converter can all cause high hydrocarbons.
Thanks. Is there a way to determine the specific cause?
