Re: A/c pressure conformation.

I am not so sure that would help Dave. At 80-90% humidity they don't even show anything for 100F. More is probably not better. I suspect you are doing good with 75f at that outside temp and...

Re: A/c pressure conformation.

Hi Dave,

I am no expert but the pressure will also rely on the relative humidity, not just air temp. Looking at the performance specs in the shop manual these would be about right for R12 (so in...

Re: Exhaust Manifold Stud Oil Leak

It may seem counter intuitive but I would also check the oil pan bolts. I went through all the usual culprits and did not find the source of my leak. The leak included oil on the driveway and light...

Re: 1990 LT5 emissions fail

I think you are right. It was that connector that was the battle!

Re: 1990 LT5 emissions fail

I see, gpm vs. ppm is all. Just different units of measure.

Sounds like a plan. One sensor is easy and the other, I forget which, is a PITA. But like you said, cheap swap of old parts. Good...

Re: 1990 LT5 emissions fail

Are you sure it is 3.5 ppm. I just ran my 90 through California smog, no small accomplishment, and it passed NO. We are on a "dyno" and it was 388 PPM at 15 MPH and 306 at 25 MPH. Max allowed is...

Re: Finally passed emissions!!!!

I think quite a bit. As soon as the ambient temp dropped NO became a non issue.

Re: Finally passed emissions!!!!

It was AA Smog Test Only at 14501 Redhill Ave, in Tustin. Let me know if you need more info. I am not sure it mattered that much other than the tech was willing to communicate with me. I asked...

Re: More smog problems

My 90 just passed. Long story short NO was only a problem when the ambient temp was high. When I passed the other day NO was in mid three hundreds. It had failed the week before when the ambient...

Thumbs up Finally passed emissions!!!!

Today was a good day here in Southern California. The ZR-1 made it this time. Well within limits on NO and CO, a close call on HC, but it passed! Final config was:

New injectors
New O2 sensors...

Re: Tough VA emissions - need help

I finally passed today, but just barely. I hit 76 on my HC and the limit was 77. NO went fine this time so finally I am good. 48 sounds hard! :mad:

Re: Emissions -- Bah Humbug!

I don't think they are trying to make it easy for us. I saw the fan there and even asked if the car wasn't getting hot. No answer. :censored:

Re: Tough VA emissions - need help

I feel your pain. I have a post running on the very topic, but here in Ca.

It sounds like you have a pretty hard HC limit to hit. How is the test done in Va? Is it on a "Dyno" or just in...

Re: Emissions - Updated with new California info

I have managed to talk to a guy at BAR (Bureau of Automotive Repair), we have it all here in California.

If you passed smog in 2009 you may not next time its your turn:

Re: Emissions -- Bah Humbug!

I'm afraid to ask but I figured that was the case. I was looking at the AX 6000 since it is easy to get at a good price. It might help me pin down this problem. Thanks for the info.

Re: Emissions -- Bah Humbug!

One way or the other this ZR-1 is getting on the road. But I agree, it is &$#&^%# change. Hard to believe they can change the standards required for a 20 year old car.

Re: Emissions -- Bah Humbug!

Hi Tom,

I have a scanner (3120) but have frankly only used it in static mode. I am not sure if it does real time. I'l go check. Any recommendations on scanners if not.

I did not add any...

Re: Emissions -- Bah Humbug!

Thanks for the input Jim. I am in Tustin so the 10 mile radius should mean the same limits. :-)

I was told that the standards changed a few months ago. It is a little hard to believe that we...

Re: Emissions -- Bah Humbug!

They did not enter VIN info so probably no big deal. The good thing was they would heat up the cats and the run the test. Not sure if that made a difference. Interesting that I passed great at...
