The Ford Explorer fails the first time through Aircare and we ended up putting three months insurance on it.

This time we removed the spout connector and the PCV valve. However when I disconnected the PCV valve the truck would jump to 2000RPM need drop in RPM until it dies….so we put the PCV valve back in

With just he Spout connector removed it passed…this was the results

Hyrdo carbons, max allowed .99 -- Ford was .056
CO, max allowed is 12.43 -- Ford was 2.461
NOX, max allowed is 1.55 -- Ford was 1.43 ( this one was close)


Anyone know what would make the NOX high?

I know when my NOX levels were high it was because my EGR valve wasnt working, it was becuase my hose was craked and leaking badly.

its an idea

does it really matter... it passed. When jen had her truck in a shop to get it ready for airscam it ran like shittttttttt, they told her to go through once it passes bring it back and they will set it up so she could actually drive it and not stall all the time[cheers]

They did not do an idle test

when i run the mustang through the sniffer, i ALWAYS pull the spout, which is like a vacuum advance on an older vehicle, i forget why it works, but it does.

clean the shit out of the mass air flow sencor with intake spray

why didn't they do an idle test? The last time I took my Bronco through, it passed everything with flying colors but failed the idle test, and just barely at that. It cost me an arm and a leg on temporary permits while my exploder was getting lifted. I freaking hate aircare!

The spout conector disables the computers control of the advance so the truck is running at base timing which is retarded back a ways from running timing.

and they do a different test for 92 and newer vehicles than they do with 91 and older the 92 up test is a variable speed test only I believe.

NOx is related to combustion temps, EGR controls NOx. Higher the temp, the higher the NOx reading.

key to passing aircare is just drive bout 60km at a high rpm to heat ur motor up and go through aircare with a hot motor. so far for me its worked everytime

I find that if NOx id high the EGR needs a good cleaning .Take the vehical on a good long run to get a good heat saturation into the cat converter.

when was the cat changed last?
i had issues like that on one of my old aerostars even pulling the the connector didnt help so i put in a after market 3way cat and it flew through air scare and it cost like 90$ and you could always pull it out after to keep for next time you need air scare since they only last a year or so if you leave them in.

taking the timing out makes for a very cold chamber
hard to make polutants when barely burning any fuel ina cold chamber

Honky what year is it???
Gen 1 exploders (like mine) had problems with the cat's
Change the cat and O2 sensors and it will
1- get better fuel economy
2- pass air care
3- cost a crap load of money...lol...

The reason it passed with the spout disconnected is prolly because the timming is kept low (no advance) which didn't help the NOX readings..
This is an old non-DIS system trick, back your timming down 10* and run it through.
You got lucky... You have no advance with the spout unpluged. Bet it had no power...lol...

Dose this sound like I'm a Ford Tech???

Oh I Am again...
