I'M HAVING TROUBLE PASSING EMISSIONS, HYDROCARBONS ARE HIGH.

1989 Isuzu Amigo • 211,000 miles

I've done a tune up and the rotor button, distributor & plug wires are only a yr old. Set the timing but it seems like it's getting too much fuel (I can smell it) plus it's cutting out. Is it possibly the O2 sensor? I'm at a loss.

Change the o2 and advance the timing 4 degrees. Check the pcv valve oper. Make sure u have clean oil when you go. These will lower your hcs.
