Running out of idea

[91Sherwood]

Hi there,

I bought a 04 MM and it has no EGR, Cat, and not sure it will pass the NJ inspection. I have this car tune to perfection. I took it for inspection and emission will fail due to the listing above. Any idea how can i pass this inspection without going to spend tons of money...?

Thanks,

Are all 4 cats removed or just the rears? First two should be good enough.

[DOOM]

Is it throwing a code?

Do they also do a visual inspection in jersey?

If the EGR is turned off in the tune it may not pass. If you only removed the rear 2 cats, that wont make any difference as long as the first 2 are still installed. You may have to reinstall the EGR and turn it back on in the tune if it fails. The only way to find out is to bring it in.

If you don't want add all the stuff back on you'll need to find someone that will pass it for you......

How is the computer not throwing a cat efficiency code w/o at least the first set of cats. Did someone fit the short lived rear 02 simulators?

I'm afraid you'll just have to bite the bullet and spend the money on some high flow cats and get the EGR working again. Unless it's a track only rig there really isn't a good reason to delete the EGR as it doesn't affect WOT performance, since it isn't active then, and actually helps with MPG in part throttle cruise.

Rear O2 sensors are probably turned off. You'll have to either add some cats or "fake" cats, reinstall the EGR, and turn both back on in the tune. Then get some MIL eliminators for the rear O2 sensors.

If you have no check engine lites and only two cats make sure the car is all warmed up b4 you try going through inspection. Second set of catsis for start-up only and once the car warms up they become redundant. NJ now is only doing the sniff test and the OBD looking for code failures. If you have a OBD tool clear any codes and give it a shot.

[91Sherwood]

There is no code anymore since i have it tune...Running great....But the inspection show that the EGR is incomplete, Cat in complete....There is only 2 sensor on this car....the triology has a plate where the egr goes....dont know why the egr is not in its place.....The test station said if it has 3 strikes it will fail.....i was going to take it to the tuner again tomorrow...now its such my luck it snowing hard here in NJ....I dont even have normal tires in it.....i have to drive it when theres no snow in the ground...The problem is that the temp sticker is good till tuesday...12-28. If i can just get a sticket without going to install any of this stuff.....car running great....

If the drive-cycle tests are showing up as incomplete, then they aren't turned off in the tune. If they were turned off they would say N/A or unsupported. Have your tuner turn them off and try the test again. That may fail, too, as some states (like MA) only allow a certain number of N/A scores. In that case, do as EMAS said^^^; there's no benefit to having the EGR removed, so at least add that back.

There's no reason a Trilogy car should fail unless someone messed with the supplied tune.

[FordNut]

If it has a Trilogy, get the EGR tube (it's a special part from Trilogy, not the OEM part) and reinstall the EGR system, hook up MIL eliminators to the wires for the rear O2 sensors, and install the stock Trilogy tune. Drive it several times to clear up the drive-cycle timers. Not much chance you'll be done by Tuesday.

The EGR tube listed for the Trillogy is P/N 4W33-9D477-A. You might be able to order it at any Ford Lincoln Mercury dealer.The MILs may not be needed. Just have your tunner turn the second set of cats off.

That is a Trilogy special part number, not a Ford part number. If the second set of O2 sensors are turned off it will fail the OBD2 test. If they are turned on and the cats are removed it will fail unless MIL eliminators are installed. If they do a sniffer test it may fail anyway if the cats are removed, but it won't be because of the OBD2 codes it will be because of emissions.

Does NJ allow for collector car plates, some states suspend emission testing for collector cars, such as Ohio, who uses the same emission testing system as NJ.

Are these the MIL he needs ?Mustang Plug-in MIL Eliminators at AmericanMuscle.com - Free Shipping! (http://www.americanmuscle.com/stmilel.html?gclid=CMXK9JiHi6Y CFYSK4Aode2zPnA)

Those should work but he'll need bungs and the sensors installed, so it can still check the heater circuit, and has a signal to delay and reduce it's amplitude.

[FordNut]

If there are no bungs currently installed, there are some "special" bungs available. They are deeper than normal and keep the sensing element out of the exhaust flow, shielding them and reducing their efficiency and making them less efficient. That makes the car "think" the exhaust is cleaner than it really is.

That makes the car "think" the exhaust is cleaner than it really is.

They are called O2 Defoulers. They are basically 18MM sparkplug de-foulers that like you said, thread into the 02 bungs to put the element out of the exhaust flow. We had to install them on Tommy of Sparta's 07 mustang after the long tube header install. JDM engineering sells them for $50, or you can go to NAPA and buy the plug defoulers for $5 and drill the ends out so you don't crush the O2 element.

[EMAS]

Shouldn't really need to put the deep bungs in, the MIL eliminators should take care of reducing the amplitude of the signal. You do want to make sure that they are located in aprox the same location as they were from the factory. The computer "knows" how far down stream they are supposed to be and that affects the offset of the 2 sensors outputs. For the Cat efficiency test the computer is looking for the signal to be about 180 degrees out of phase, ie the rear says rich while the front is saying lean and vice versa which is affected by the distance between the front and rear sensor.

Getting a pair of 18mm spark plug non-foulers available at your FLAPS will be cheaper than purchasing true O2 bungs and should be in stock in the HELP!/Dorman section. While you are there pickup an Autolite 45 spark plug. Cut the non fouler in two just under the hex and screw the spark plug in to it to use as a handle while welding the bung and if you cut it thin enough it will center the bung in the hole. Of course if you are going to have an exhaust shop do it they should have bungs and their own method of holding in the proper location. You also want to make sure that the wire end of the O2 sensor is pointing at least slightly up to prevent condensation from collecting in it and damaging the heater or actual sensor portion.

My luck....I am about to take it to the tuner shop and it snow heavy her in NJ.
I love this car....but seems like it does not want to go anywhere since the temp inspection already past.....I might just have to get the sticker on my Van and use it....lol...but all the info you guys gave me i will definitely share this to the mechanic.
I love this site....you guys better than HAYNES manual....

[ctrlraven]

Haynes manual suck anyways. lol

[91Sherwood]

your right.....and not to easy to follow.....i will keep you folks informed on my progress....and hopefully get that sticker......thanks for the assitance...
