Any ideas on what to do? He said it was my cat but just wanted to see what you guys would think. 95 Integra gsr, I put all my stock internals on and only thing on right now are usdm itr mid pipe and comptech axleback and I extended my usdm oem gsr cat to reach the itr piping. Besides that everything was stock when I brought it in this morning. Thanks in advance!

 

u should run it hard on the freeway for 20-30 mins to get the cat nice and hot before smog. what was your timing set at?

 

It's not that far off. You only need a new cat when your numbers are double or triple the max allowed. Get the cat really hot and leave it running while you wait to get SMOG'd. Also, change the oil if you haven't already. Old oil is super rich in HCs. Check tire pressure, timing, and get fresh gas from anywhere but Shell.

Good luck.

 

I was thinking the same, well I was low on gas, went to the place 5 mins away from my house after a cold start and I'm due for an oil change lol. So I think I had all the bad elements of making that happen. Could that be it? Simply get gas, oil change and get my car hot as hell for the smog?

 

Ttt any other opinions or thoughts??

 

Turn your timing to 14btdc. Be sure it's on. (might not drive as good as 16btdc)

I'm sure by the time you drive it to your smog station it'll be hot enough. You can sit in the car and keep the rpm at 2500, 30sec-1min before they are ready to do your car. Wouldn't matter if you drive your car on the freeway for 30 min and they have you wait for 2hours then your cats cold again.

Oil change. Spark plugs/wires and rotor would be a plus. At least if you don't pass you know there are things that are crossed off your list of things to check. But if you're only off by 7ppm, then maybe spark plugs and wires will fix your problem.

 

I think that's what I'm going to do, oil change since old oil is rich in hc's and then just keep my car on after driving a bit til it's my turn. Ill let you guys know the results after!

So when I first went for a smog I had no gas, due for an oil change but with no check engine light on and stock internals. Today I got gas after fuel injector cleaner, did an oil change, put in that guarantee smog check emission fluid pass in and drive my car for a good 10 mins and when I arrived at the smog station I kept my car on to keep the cat burning hot. Once tested I passed with flying colors. So I'm pretty sure little factors like these will do the job. You'll only need a new car is your numbers are 2x the max or more. Buying a cat should be the last thing to buy. Hope this helps to those in the future

 

good job. glad it passed.

 

Thanks for your help and sorry for abc check and bad grammar, on my phone lol
