I got my RV back today (for a little while) I am having a hard time believing that somebody would try to get away with this in CA. This story continues, it is NOT over yet. Let me start with some facts:
On March 13, 2009 when I had the smog test done in King's Beach, CA, it flunked, and here is the info.
Idle speed was 625 and the HC measured at 190. 39 is average for this vehicle (2000 Tioga, or, Chevy Express Cutaway, 7.4L, MPFI) and 150 is the very max allowed. So it then flunked with the 190.
This RV was picked up by the dealer and was sent out for a re-test on March 19, 2009 (Yesterday):
This time it passed, BUT the print out shows:
Idle 1067 !!!!!, HC only measured 68.
The RV would almost not be drivable at such a fast idle, so it's obvious to me that they CHEATED to make it pass. I cannot believe anybody would try something so stupid in CA unless they are trying to be put out of business by the BAR. I also have a hard time believing that the max idle allowed for this vehicle is so high, when it's controlled by a chip in the ECM that will keep the idle around spec (which is ~650 RPM). And idle at 1067 proves there is something very serious wrong and my RV has never idled anything near 1067 under any conditions.
It's obvious to me that they used the "stick" they use to hold the gas pedal down for the 2500 RPM test but set it for the upper allowed idle to make it pass. Illegal as can be here in CA!
So I called back the dealer. We made an agreement to meet at the smog test place where we could watch the tester do a re-test at the real idle speed.
The RV was very warm after to 80 mile drive to get it there (makes it MUCH MORE likely to pass because the catalytic converters will be hotter) and they were able to test it right away. The did and they got a HC reading of 460!!!! Yes, 460, more than three times over "gross polluter"!!!! A gross polluter is when the HC reading is more than double the max reading (of 150).
Of course the guy tried to Bull Feed me , with all types of nonsense but I simply said "I am not trying to get anybody in trouble, I just want it fixed correctly". I also explained that I knew enough about vehicles that he will not be able to "bull fed" (I really used the other term:)) me, but if he wants to continue to try, he will end up arguing with the CA BAR instead of me.
At that point, they decided to keep the RV and fix it right and let us have a car to get home in.
I am quite sure now the problem is the older catalytic converter. They tried to be cheap and only replaced one before I purchased the RV. Seems when they go out, they get worse and worse very fast. IAC there's no excuse for a "test only" station to do what they did.
I do wonder who the other culprit is between the RV dealer, the repair place and the "test only" smog place. Obviously the "test only" station did what they did for somebody to save money at my expense.
I do not want to get in a situation where I will have to fix this at my expense next year when it's their problem by CA State law. They illegally sold me the RV without completing the smog test.
In just gasoline alone, I have spent a lot of money on this problem of theirs! Drive to Truckee, drive to Kings Beach, drive to SSF, they pick it up on a full tank to drive it to Livermore and back. Tom & I drive it to Livermore today. And then pay sixty bucks for the failed smog test at King's Beach. I wonder how much the RV dealer will reimburse me for all this.
At least I will get the registration as they illegally made it pass and it's unlikely anybody at DMW will notice. But I certainly noticed. I bet they could get away with this with 99% of the population and so they took a chance with me, not knowing I would check the VIR (Vehicle Inspection Report) and understand it.
This Monday, they are going to put on a new catalytic converter to replace the one old one and I assume that will fix it correctly.
BTW, does anybody here know the minimum temperature that a catalytic converter is effective at? In RV's they are often a bit more critical because they are often located somewhat far from the engine where they will not get as hot.
