Car Forum / Porsche / Porshe 911 / November 2007911 failed emission test
My 1989 911 Carrera failed the provincial emissions idle test. The Carbon Monoxide %level was 1.08, and the maximum allowable level is .73. Last year the car passed the test with a reading of .41. I've seen an online add for a additive substance called "KickGas" that is guaranteed to produce positive results. Does anyone have any advice concerning the effectiveness of such products and the risk involved in trying them? > My 1989 911 Carrera failed the provincial emissions idle test.

If the car passed with .41 a year ago, and then went to 1.08, I'd be more concerned with finding out what the problem is than whether an additive will hide it. I have a Subaru that passed every year and then failed. Turned out to be a dirty contact on the oxygen sensor. Might be something really simple on the Porsche, too. >> My 1989 911 Carrera failed the provincial emissions idle test. The Carbon >> Monoxide %level was 1.08, and the maximum allowable level is .73.

I don't think the solution to your problem comes from a bottle. I just used something that was gaurenteed to make your vehicle pass or double your money back. I got it a pep boys. Run it thru a tank of gas and refill your tank and it passed with flying colors. My HC's were 118 (passinmg was 95) and after it was at 78. > My 1989 911 Carrera failed the provincial emissions idle test.

I recommend checking the Oxygen sensor. best priced ones are on PelicanParts.com > My 1989 911 Carrera failed the provincial emissions idle test.

If you haven't driven your 911 and it has been sitting a while before the emission inspection it may not pass. Take it out for a nice long drive before your next inspection and you'll see the difference! > I agree as well....it's not out of a bottle. > [quoted text clipped - 10 lines] > > results.

It's good advice and I know things can get slow around here, but you've just replied to a two year old post. DS |
