Wow is that small

Ill try and help out as soon as I can see

 

haha sorry, im tryin to resize right now. anyways the PPM for the 25mph saids that i measured 850 but the max is 798.

 

get a new cat if you don't have a new one allready.

try some GM top engine cleaner do a tune up your nearly pass soo it shouldn't be hard to pass

let me see the chart!!!

 

Just run alcohol

 

Pic is too small....

 

pics are up!

 

Hey! It's not your cat...run the Guarantee to Pass Emissions Formula in your gas tank..you can purchase it from any Auto Store. if your cat was the problem, your CO and HC would be off the charts... Since our cars don't run EGR valves, you might want to try and do a tune up, and run that stuff i mentioned earlier...

Just so you don't think i'm bs'n you...I just had an emissions test done also and your CO and HC numbers match mine very closely and I have a new cat on my car! if you're still not convinced let me know i can post the proof.

Take it easy!

 

Im not seeing a pic, dam computer. I used the **** hes talking about above and it costs like 8-9 bucks for a bottle and it did the job

 

is it because the motor is running rich, is that why i didnt pass?

 

let me guss your cat is OLD!!!

if yes change it you will pass

 

thanks guys, ill try that stuff and ill let you guys know what happens

sorry but your wrong stop passing the wrong information

 

ok, i will try to get the cat asap. thanks

 

Magic elixirs only band-aid the problem temporarily.....Fix the REAL problem and you wont have any future problems....Some laws were set up for a reason...Although I would hate to live in Cali b/c of smog laws, it does have some of the nastiest air and dirty cars isnt helping any bit.

bossman what are you like in the 5th grade? wow i forgot you're da man..

anyways.. dude with the cat problem..take it off and Check it out...if the internals of the cat are broken, then replace it, also check it and see if you see any blockage..hold it up to a light and see if you can see through it. If you can and there is no damage to the internals, don't swap it...
It's gonna be a pain in the *** to take it off, bolts and nuts will probably be rusted. I suggest getting replacements bolts before you start just in case, get the gaskets also... you don't want to get stuck. Likely the bolts that will be rusted will be the three connected to the exhaust pipe..(rear part of cat). Spring bolts should be fine.

bossman suggested replacing it, but that's 150 some bucks if money is no object all is good..or if you're like the rest of us and can't dole out 150 without consideration you can go out and spend 8 bucks and one weekend and use that emissions liquid i suggested earlier. read the instructions on the box..

either way It's your call...worst case scenario if you don't pass you're out 9 bucks but you still get the benefit of it cleaning out your fuel system.

Post your results when you're done...and your emissions record and what route your went.

Take it easy!

NOT TRUE!......I failed NOx only and changed cat and it solved problem. Passed everything else my first time but NOx was really high. Cat can, and most likely in this case, clean up emissions right away.

 

Sorry to bust ur bobble.

But I have been to the ref about 5-7 I cant remember how many times soo and I know what I am talking about if you want to preach but at least preach the right information.


If your cat is 13years old it should be replaced if your failing emissions.

FYI: I had an old cat like yours getting a new cat reduced nox and HC nox buy 350ppm and hc by about 70ppm.

and your about to pass but try some cheap solutions first but if it fails again go ahead change the cat it will pass for sure. I don't want to argue with you bro.

word

also I might be in 5th grade at least I know my ****

 

thanks guys for all your help. sorry for the fights and arguments.

 

U just barely failed NOx, so i wouldnt replace the cat. It doesnt appear that it is totally at fault. It seems that if that is the only thing that failed (assuming your ignition timing is dead on) then run some of GM's "top engine cleaner" to clean up some of the carbon build up u may have. NOx is caused by too high of combustion chamber temperatures. What causes those high temps can be a lean condition, too far advanced ignition timing, carbon build up creating higher compression (thus more heat), etc.
