Ok here's the deal I'm trying to sell my 89 GT that I just put a crate motor in that has an E303 in it, I just got a valve job and it has a 65MM TB, other than that it's stock, What could be wrong? I need help, or a smog....Please help I want to get rid of this thing.

So you have the stock exhaust set-up and you can't get it to pass?

I find that hard to believe.

What part of the test did you fail? Could just be something easy like a dirty/bad egr.

Cough up the specifics and maybe we can help.

I've also had a couple different people say Berryman's cleaner will do the trick.

I've got a BBK H Pipe with Cat's and Flows, Maybe the cats are bad? The printout says this:

At Idle 793 rpm
0.33% CO 2000 PPM HC

5.3% CO2 12.9% O2

2954 rpm

1.57% CO 441 PPM HC

11.3 CO2 4.3% O2

I don't know what they all mean?

My throttle emissions looked like that and it was the cats. Could also be bad O2's as well. If that is the only part of the test you are failing, my money would be on the cats.

Buy new cats that will get anything to pass the sniffer.

I have stock H Pipe but I'm afraid that might be bad too! So I guess I'll try to read the codes on it first and see if that works, then it's process of elimination, Thanks for all the help, keep the sugestions coming.

Put some new cats on there. The high HC (hydrocarbon) readings show the cats aren't doing their job. If your engine was running too rich the CO (carbon monoxide) readings would be higher. 5-6% CO is a fairly rich engine. Your CO readings are fairly low. However, the low CO readings and the high HC may mean your engine is running too lean and judging from the low CO2 readings and the high O2 readings, it looks like you have a vacuum leak somewere. Replacing the cats should clean up the HC readings.
Did your car actually have the somg test run? If so, with the HC readings you have your car should have been labeled a "gross polluter" which means a smog certificate can only be issued at a "test only" facility once the repairs have been made. Good luck.

The cats use oxygen(02) to reduce HC and CO. Those numbers tend to indicate that the cats arent using all of its oxygen to reduce HC and CO(eventhough CO is not excessive at idle). As others have said a set of cats may be the answer, if you want to make sure a good smog tech should be able to check the cats. Hope this helps.

To answer some questions, I did just pre test it so I'm ok so far, I guess I'll try cats first and go test it again, I just don't know any ford guys that can help me....Thanks again guys.

I've got my stock H-pipe just sitting in storage if you want to borrow it for smog. My car passed smog right before I bought it last june. Hopefully my bassani 2 cat x will do the trick next year when i have to pass again...

First things first,
The high rpm test is invalid, maximum rpm for that test is 2800 rpm
Secondly, it shows that you are running 793 rpm w/e-cam, you should raise the idle up to around 900-950 rpm
Thirdly, the advise of putting new cats on a car the runs 2000+ ppm hc at idle is not only wrong, it's fucking retarded If you put new cats on a car running that poorly, you'll be lucky to get it back to the smog shop before the new ones are ruined.
While it is possible that the cats are bad, I would fix the problem FIRST
What is the timing at? my guess would be 14-16 BTDC, set it to 8 BTDC
The 12.9% O2 is way too high even for an air pump equipped vehicle, you have a vacuum leak somewhere.
Judging from your "invalid" high rpm readings you're running too rich, check you O2 sensor ground wire (located on the back of the driverside head) Have the O2's ever been replaced? What size injectors? What's the fuel pressure set at?

Great Advise! ........I do have to disagree about the timming though....It makes sense that its probably off, but a good smog tech would set the car to the standard 10* timming for the test, right?...

Pay the extra $$$ and get an illegal smog within the next month b4 the new dyno smog law takes affect in june....if you wait that long you might be stuck with that car, i just had to do the same thing with my 87 gt that im selling.

My timing is set at 10, I'm running 91 octane, do you think running the codes will help? Like I sadi in the previous emails everything else is stock, except the cam and TB. I just need to get this done I'd pay for one to get done but can't find anyone.....

Has anyone used clean power before??

What you need to do is re-install the stock four cat h-pipe and go down to the smog station. You can take something like a pre test where even if you fail it doesnt go on your record and it doesn't go to the referee but if you pass it doesn't count either. I would do that and see the results with the stock catted pipe. If it passes the pre test then pay for the real smog test and you should pass. Bump your timing they never check. Put in 91plus fuel and maybe an octane booster and you should be good to go.
