hey fellas, got a 1992 ranger XLT, 2.3L manual with 79k on it. Failed Komi-fornia smog test again today. I am only failing with hydro carbons (unburnt fuel) at the 15mph test. i am passing HC in the 25mph test (i am right on the limit but still passing). I have installed new plugs, wires, cleaned the Idle air control valve, cleaned MAF with proper CRC cleaner, new K&N air filter, fresh oil change and filter less than 100 miles ago, new O2 sensor. I can only guess maybe catalytic converter or coil packs? I repaired all previous codes (172 was o2 sensor), and i had code 341 because some ass-clown mechanic yanked out my octane adjustment pin and retarded my truck 4° and made it run like SHIT. anyhow, after plugging the shorting bar back in, truck runs great, ALL my power is back. I ran the code scanner again. i have code 1-1-1, SYSTEM PASS! I notice my exhaust still smells a little gasssy/rich, and i have an occasional hiccup where the RPM drops lower or stumbles for a split second every 30 seconds or so. any ideas? i am totally lost, im poor so i really dont want to take it to a komifornia ripoff artist turd shop; and get bent over for something i'm capable of repairing. so, again, the issue is (hydro carbons being about 3times higher then average) so i need to pinpoint WHY my HC is jacked up so high. Im guessing the coil packs are starting to give out if im getting the occasional hiccup? or clogged up cat (from my truck running in retarded mode getting 15mpg for a few thousand miles?) help me out guys!
