my hc(ppm) is too high.. what do I do?!

 

Notice your NOX is low and HC high, that usually means the 02 might not be working, or a bad injector, check them with an ohm meter, should be 12-18 ohms.

When the NOX is low, that indicates cool combustion ie. rich mixture.

 

i have brand new injectors bosch III old ones were ohming low...maybe it killed my o2?

 

well when i failed emissions on my car everything failed. So what i did was i bought some techron fuel injector cleaner and filled my tank then poured it in and ran it for about 100 miles then i bumped my idle up to about 900 and the day i was scheduled to take the sniffer test i drove it on the freeway for about a half hour till it got nice and warm and then went right to the testing station and had them pull it in without shutting off the car. Since i did that it passed with flying colors also check your plugs and timing

 

Which of your cars is that so I can add it to my chart.
make, model, year, engine, year, trans,

 

If the engine is stock, are you using 22lbs injectors?

 

That was my issue as well.I retarded the timing a couple (maybe more) degrees & raised the idle speed a couple hundred too.Plus the unsual, inpect/clean plugs,check/replace cap & rotor.I also poured a bottle of that Lucas fuel/octane booster thing.

 

theyre 22lb injectors the car has a 350 but is tested as 90 irocz 305 700r4

 

oh and i picked up the totalled 02 ss today will post pics tomorrow

 

Could having the fan running with key on have had hurt my #s? I go for a retest tomorrow................

 

do you have the A.I.R. system in? I didn't when I inspected and that's how my smog failed.... just throwin' the idea out there

 

That does typically fail you. It causes the car to run rich and throws everything else off

 

My car likes to run about 140-160 around town.So i took the air dam off to spike the temp into the 200-210 range.

 

swapped wires, cap, rotor, coil, plugs, and 02 sensor still didnt pass. ended up paying under the table, no lube.

 

I know the feeling.Least now you dont have to worry about the registration while doing the swap.
