Failed smog BIG time...need help

You are in virginia. And you drive a d1.
Get some used 02 sensors from Will Tillery and see if that works. $100 at the max, if that doesnt work and you need new cats, talk to him about that or find someone in florida who doesnt need cats(no emissions) and give them $100 for each cat.
Problem solved.

Put 2 or 3 bottles of winter gas line antifreeze, or more if you have to. Drive to test facility and pass with flying colours. Immediately after top up full tank of fuel.
Alcohol burns cleaner but does tend to damage some of the older rubber gaskets and fuel lines.
I've use this on many, many cars and the guys at the facility can't believe the results.
Mind you all the basics need to be done prior. New oil, air filter, and whatever else is essential to yor motor. Timing also has to be set correctly.
Good luck.

Okay, so did oil and filter, injector cleaner, new NGK regular plugs, trans drain and fill (will do filter later when I feel like dropping the three link crossmember), air filter and cleaned the MAF twice. New numbers put me at 285 out of 125 at idle and 84 out of 125 at 2500. So, I'm 50% pass. I'm thinking timing related at idle? I don't think its O2 sensors since I went through without issue at high rpm.

I wouldn't call 84 out of 125 "without issue", but you're getting closer. Were the cats hotter than last time?

For my goal of just getting it through inspection so I can get it registered long enough for the diesel swap, a pass is all I am looking for. I dont care about how much or how little it does it in. Whats funny about the 2nd go through is that the dilution was actually worse with all the new stuff but the results were better.
- At idle, I failed with a 289 and a limit of 125 with slightly lower rpm and a dilution of 14.0. Originally, it was 432 and a limit of 125 with dilution of 14.2.
- At 2500, I passed with an 84 and a limit of 125 with a lower rpm and a dilution of 14.2. Originally, it was 253 and a limit of 125 with a dilution of 14.5.
Im going to check timing tomorrow and Ill see if I can replace the PCV valve tonight. I drove it a good 40 minutes and pulled it straight into the bay for the inspection to start. I didnt clean the throttle body out. I forgot all about that.
Oh, also, I inspected the O2 sensors yesterday. They looked new and the wire leads were really clean. With the underside as dirty as it was, they stood out a lot.

Run it all the way low on gas, put in 3-4 gallons of E85, go and pass emissions. Fill tank.
I changed the oil and filter and it seemed to help the last time I didn't pass. Dunno if it mattered or not...

Oh, I know where you're at on this. What I meant was, your truck obviously still has a problem, even though you're "closer". So it could still be your O2's. You say they look clean, but I don't know how well that correlates to function.
The E85 thing might work. That'll lean it out. If it still fails, and is still running rich, then I definitely think it's the O2's.

Yeah, I know but the truck has done 500 miles since the last time it passed emissions inspection. It did, however, go through a mud hole or two so I was expecting to see them trashed but that wasnt the case at all.
E85, huh? Not too sure I can find that around here at a regular station. What will that do exactly?

E85, 85% ethanol. Ethanol has about 50% of the energy content by volume as gasoline. Therefore, it'll lean it way out. It'll also eat seals, and the aluminum intake over time, which is why you don't want to leave it in there long.
Even using E10 would help, if you normally run pure gas, E10 will run about 5% leaner.
If your O2's are bad, which is why you're running rich, then the engine will adjust and add 5% more fuel, getting you back to running rich. With E85, I doubt it can even adjust that far. Of course it might set a code too.

Update...of sorts. Timing is spot on as it should be since the distributor is only two months old. Doing O2 sensors and coolant sensor tomorrow afternoon. Hopefully that will solve the issues. O2 sensors look new but Ill replace them anyway. Looks like a fun job. I have to lay across the top of the motor to reach the harness on top of the bellhousing. Sweet...

I should have mentioned coolant sensor earlier, but I assumed you would know if that was gone due to the temp gauge.
I had an 89 VW Rabbit, the coolant sensor broke, but there was no indication. No CEL since it was pre-OBD. And no temp gauge. But, the electronics thought it was infinitely cold (back in the analog days), so it richened the mixture infinitely much. I barely idled, left black soot stains on the ground and dribbled raw gas out the exhaust. Ran better the faster I went.
I assume you would know if yours was gone, but who knows.
Try getting the O2 sensor connectors from the bottom? That's what I did on my D2. They were still a bit of a PITA.
