Effed up fuel injectors can also cause the idle emissions to be poor. When my car failed last time it was because the fuel injectors were crapped up. Had them professionally cleaned and all was good again.

I just took Vicky to get inspected today and it failed for HC and NOx. Passed for everything else though. Are the two things intertwined or are they affected by different things?Comment

NOx is usually EGR related problems, HC is frequently blowby, oil burning, or bad converters. Was the car completely warmed up? how much did you fail by? Sometimes what helps is just taking it for a few mile drive in D at highway speeds to clear the garbage out of the motor before visiting the sniffer, especially since that car sat a while.86 Lincoln Town Car (Galactica).

In D? Hey I guess I could try that. The HC was 172 and the limit was 152,Originally posted by gadget73 View Post
the NOx was 1151 and the limit was 1146.
Car was completely warmed up. The engine has developed a miss, so I'm wondering if that's what caused it to fail.Comment

check your timing too. Normally, these will pass with HC's in the double digits and NOx way way below limit. Those figures look like what I'd expect to see with no converters. Are you sure they're not hollow?86 Lincoln Town Car (Galactica).

Timing is 10* BTDC. With spout removed.Originally posted by gadget73 View Post
I'm pretty sure my sister didn't drill out the cats lol. And I definetly didn't. The engine does have a miss in it, at any speed, it does smell a tad rich.
Also if it makes any difference, the CO% was way below standard. .25 was what I had and the standard was .86Last edited by 86VickyLX; 11-14-2008, 11:41 PM.Comment

a miss will show up with unburned fuel, aka hydrocarbons. Fixing that would likely help the emissions figures. How are your plugs and other ignition parts?86 Lincoln Town Car (Galactica).

Plugs are kinda old, a couple of years but they're probably fouled from me revving the engine and just going up and down the driveway for so long. The spark plug wires are old. I should replace them, what brand do you recommend? The distributor cap has been replaced at least once. Rotor too. Anything else I should check also Thain?Originally posted by gadget73 View PostComment

I replaced the wires and plugs today and drove it like hell on the highway. At least 10 times at WOT, shouldn't be anymore carbon after that, the needle was past the reset button for the trip odometer (110?), lol, it seems to run much smoother now, wondering if the miss is part ignition and part fuel. The miss has gotten much smaller, but it's still there, and to my nose the exhaust smells the same.Comment

is your car carb john? the fuel could be turned up a touch.Comment

I know im gonna get crap for this but as some already know i run acetone with my fuel when i got the car it wouldnt pass mass emisions no biggie im sationed in nc decided last time i went home let my father in law borrow it for a month still cutting the fuel with acetone the results were as follows.
hc grams per mile .30 max 2.00
co grams per mile .16 max 30.00
nox grams per mile .79 max 3.00
co2 grams per mile don not apply again just my

acetone is basically fuel injector cleaner, so it will un-gunk the injectors pretty effectively. If one was sticking open a bit, that would do it. If you read the ingredients on a lot of fancy fuel system cleaners, its basically mostly acetone anyway. The ones that claim to be "made with jet fuel" amuse me the most, jet fuel is basically kerosene or a kero-naptha (lighter fluid) mix.86 Lincoln Town Car (Galactica).

I am pleased to announce that Vicky passed reinspection! The hydrocarbon was 1 under the limit, and the nox dropped considerably. Standard for NOx was 1146, my reading was 240 something. Standard for HC was 152, I had 151. This was a big change from 1151 NOx and 172 HC.
Turned out the EGR valve was being a bitch. I replaced all the vacuum lines for the EGR related shit. No problem. The Valve was working properly since the car almost died when I put a vacuum on it. happy New Year!!Comment
