It depends on your local regulations, and how carefully they inspect the car. It is a violation of Federal law to change the location and number of the catalytic converters. If 1) they enforce that law; 2) the know the correct setup for your car; 3) they take a careful look at it, you would fail. Unless your car is specifically a 1995 CA emissions A4, it left the factory with one cat. If you have two, and they are not located in the stock positions, you are violating Federal law. Doesn't matter where you live. All that matters is whether they enforce that particular requirement.

With two healthy cats, running at the correct (hot) temperature, and with a good tune, there is no reason your car should not be able to pass rolling emissions.

 

Yeah Im not really worried about it.

And the cats Im gonna use look almost brand new, and with two of them I should be fine. Im gonna try to go thru on monday.

Also I heard if your exhaust doesnt come out f the back of the car you have to bring something with you to extend it??

 

Ok. I went to test today and I got this....

HC - 1.03 Limit: .80

CO - 12.37 Limit: 12.00

NOX - 4.42 Limit 2.00

My exhuast is as follows.. Pacesetter LT's with a cat on each side and it exits vefore the rear tire on each side (Temporary)

My SES light comes on when Ive been idling for awile and my alternator makes a grinding soound

The car runs fine before light comes on and doesnt change with it on..

Ummm I drove 30 miles and lost 1/4 tank... Idk if that is related to my results.. Im kind of lost as to what to do.. If it pertains... I extended my own 02's.. PCM side tho. I also redid the wiring to 4 injectors and 1 I wasnt sure if I did right becuase I pulled both wires at once and they werent different colors.. but a 95 wont throw a SES for a misfire... so I dont know, any help is appreciated...


Thanks

I think you're best course of action at this point would be to scan it for codes if you have an SES light illuminated.

 

I dont have a way of scanning it... its a 95....

 

You can scan it with OBD-I software (FreeScan, DataMaster) or any OBD-I scanner with the jumper wires shown on Shoebox's website.

How close to the collectors are the cats located?

 

Pretty close. like max 6 inches away. they get hot!

Um double checked voltage to the injector I was iffy on and it has 12V..

Sounds like I have an exhaust leak also.. maybe its a 02 code?

I need to pass within two days because im driving on a restricted 3 day permit

[edit] Ive tried that soooo many times and it seems I cant get the right scanner :/

 

I pulled everything off and retourqed the intake and none were loose.

When I pulled the TB off it smelled terribly off gas. So obviously im dumping fuel somewhere... but how???

Like I said I did extend my own 02's from the PCM side. Also upon start it smells bad bad of gas? Loose spark plug?

Another thing. I was going to go back to using the Opti but broke the rotor. So i put the Opti back together without it. using CA glue where the rotor holes were to keep the Degree wheel on.

Also when the guy driving my car on the dyno and when brings it up to about 2500 the ABS light comes on..

I realllly need help!!!!!!!!

 

Could a loose plug make a car run rich???

 

Also now if I watch my volt gauge the volt goes down to about 12 when the fans kick in but thats like 2 minutes before the SES light comes on.

Computers suck without a way to see whats going on lol

 

If its running rich enough, the gas can be washing down the cylinder walls, getting past the rings, diluting the oil, and ending up as vapor that gets sucked into the PCV valve and the vent line to the throttle body.

Odd combination of emissions results if its running rich for the test. All three items are high, and if its running rich, typically CO and HC will be high, and NOx will be low.

If you're not using the Opti, what are you using - Delteq? LTCC? Jerry-rigging the optical wheel with glue doesn't seem like the right thing to do. Timing could be totally screwed up.

Focus on the engine problems. But this may be the result of bad ground, particularly on the passenger side fender liner.

What have you tried to scan it with? Have you used an OBD-I scanner, with the correct 16-pin adapter plug, or the jumpers shown on Shoebox's website?

 

Nothing in the Opti is jerry rigged. It starts and runs fine, no missing whatsoever. So I dont see how it could be that. Im using a delteq setup and the Light on the "Opti-Box" is illuminated so I am getting signal. Everything is plugged in as far as sensors..

If I crossed a wire for the injectors would that cause it to not have a duty cycle and to always have a 12v source???

 

I got the PCM scanned to day and I have the following codes being thrown..


23: IAT sesnor, Low temperature indicated
26: EVAP Purge Control Circuit Fault
37: TCC brake switch errorm TCC Brake switch stuck on
51: Faulty or incorrect PROM/EPROM


37 could be caused by the B&M Shift+ thing module I have.

26 states its a wiring error

23 I dont even know how I could have low temp indicated when I dont even have a CAI lol

51 could that be my tune??

 

Ring out the IAT circuit. If it checks good, change the IAT sensor. That's probably your main problem. Check your purge solenoid too.

 

I guess I misunderstood yout comment about using glue to hold the degree wheel on?????

Using the LT1-specific code list on Shoebox's website:

DTC 23 = Intake Air Temperature (IAT) sensor circuit (signal voltage high, low temperature indicated)

This has nothing to do with whether you have a CAI. If means the PCM is seeing the wrong voltage on the IAT sensor circuit. This results from very high resistance in the temp sensor, or wiring. Typically, it means an open circuit. As noted above, check the wiring, and test the IAT sensor using the method shown on Shoebox's site:

http://shbox.com/1/4th_gen_tech2.html#ect

DTC 26 = Evaporative Emission (EVAP) canister purge solenoid valve circuit

Again, indicates an "open" on the EVAP purge solenoid. Check to make sure the harness connector is connected. Measure the resistance across the EVAP purge solenoid pins with the connector off.

DTC 37 = Brake switch stuck "ON"

DTC 51 = EEPROM programming error

Will often set due to faulty PCM grounds. Triggered by a check-sum error.

Nothing to do with the "tune"
