Emissions testing in dallas tx
Well, My 87 ford f-150 302 passed.
Everything was great but HC.
Test limits for 2002 Texas State emissions :
25 mph = 148
15 mph = 152
Test limits for 2001 Texas State emissions :
25 mph = 220
15 mph = 220
On the 25 mph my reading was 94
On the 15 mph my reading was 149 - OUCH, 3 more points and would have failed...
DOES ANYBODY HAVE AN IDEA WHY MY 15 MPH WAS SO HIGH ????????
THANKS IN ADVANCE...
P.S.
Last year my tests where
25 mph = 20 HC
15 mph = 25 HC
One thing that I think made a difference is when they do the speed test with actual drive the truck on rollers. The load on the engine create true readings. Since back in 1987 they did an idle config for emissions, does that mean ford is going to supply products to the public for older vehicle to be able to upgrade their emissions so that they can pass ???
Here is the best part: IF YOU FAIL EMISSIONS IN TEXAS TWICE IN THE SAME YEAR, THE STATE CAN DENY YOU NEW VEHICLE REG TAGS... Cool double tickets... That makes my day..
Here is some info on it:

Where did you get the specs, and are they the same for all years (below 96) or do they vary per vehicle?
I have 5 vehicles, 1 of which is exempt (54), 1 is OBD II. The other 3 will have to pass later this year or next, and I would like to know what level they will have to attain to pass.

I got them from the spec sheet when I passed the inspection or the AMS.
I think they are all the same for 96 and below.
My life has a 99 ford winstar and the max for HC is the same.
So I think they changed them from 220 to 150.. Ouch..

That's really bad news. I thought they would only require a vehicle to pass what the specs were when it was manufactured. I think I will visit an inspection station and see if I can get a copy of the specs.

[updated:LAST EDITED ON 11-Jul-02 AT 05:01 PM (EST)]I think it varies by vehicle. My HC limit was about 175ppm. I just got my low mileage waiver this week. It's a pain, but they don't give you much fuss. My only dissapointment was that the test they did at the waiver station was the worst yet, 385ppm. Guess I have a year to figure out what the problems are. The truck is running great, however.

My truck just failed the emission again this morning
HC = 366
CO = 6.26
NOx = 307
I have replaced everything I can think of, and this is a new 302 long block with less then 20k
Have replaced the following;
EGR, EGV, IAC, Replaced Plenum gasket, new gasket throttle body
Single New Catalytic Converter, Thrustmaster Muffler, Plugs, Wires, Rotor, PVC.
Purchased timing light and adjusted timing to about 14 BTDC w/SPOUT removed ( I think ). Purchased a tester and getting code 11 now. Was getting 34 until I change the Cat Converter.
The truck still has a smell to the exhaust.
Aside from the waiver, where can I go from here???

Maybe check your oxygen sensor and take the timing back to 10° BTDC? If the truck is mass-air, also clean your MAF sensor.

I have searched the link but cannot find where you are limited to two chances per year to pass the test.
Also, there is a paragraph which tells that exceptions can be made under cetain circumstances, like spending over $100, or parts not available, or vehicle can not be made to pass.

I'm sorry, did you mean MAP sensor or MAF sensor. If MAF what is that !! never heard of it and where is it and how do you clean it.
Can you clean the plenum, how. What about the EGR pipe? I have reset the timing to 10 degrees BTDC ( w/o the SPOUT). The truck is running great, but just not passing emissions.
Would a bad throttle body, create this problem?
Since resetting the timing and replacing the O2 sensor (again) I have not had it retesting ( stuck in Alexandria, LA for work this week)
If I can resolve this problem the only one remaining is the get the tranny corrected. It "bucking" when decellerating, and feels like some something is shifting / moving during that time.
I am restoring this old work truck, so I literally replacing everything on the truck ( new engine, new tranny, new 3.77 rear end, needs LOTS of body work). I still need to add some A/C, it's awful hot here in Dallas !!!
Thanks for your assistance.

thood: Only 95 or so and up have MAF. What year is your truck? If both cat and O2 sensor are new and your code is 11 (system ok) it gets difficult. There are not many more reasons it could run rich. How old are your injectors? On my old diesel Volvo I once had injectors that were so worn out, they would rather trickle than spray. Injectors that are over 120k or so could certainly be one reason the fuel's not being burnt: it's not being sprayed well enough.

I guess I wasn't clear on something ( as usual), but after installation of Cat / and O2 sensor, I am now getting code 34, which means EVP sensor, which I just replaced last week. Purchased part from NAPA. I have read on some messages that their might be some difference in the correct shaft size on some of these after market EVP sensors. I had cleared up this code before, when I purchased the part, but now it's back. Do you think this will keep the truck from passing test. I was thinking of purchasing from Ford dealer to ensure I get a "good" part.

Now I think I got it, sorry. I've personally seen EGR valves not holding the vacuum in the store (AutoZone). I tested them in the store and they failed. Test your EGR valve, even if it is new, if it holds the vacuum. You can also test your EVP sensor with a multimeter. As for shaft lengths: if the voltages check out fine, just make sure the shaft is hitting the plate in the EGR valve, so the sensor always gives the correct position (i.e. doesn't show closed when indeed the EGR valve is open). If you can press the shaft all the way into the sensor, it also can't block EGR valve operation. No need to change any of those parts, if they pass these tests

On all the
EVP
O2 sensor
and so on
for emissions parts you need to get all the parts from a ford dealership.
There are over 15 different O2 sensors you can use for the 87 f-150.
You need to get the old serial numbers off the old parts and find out what the new serial numbers are for the new ones.
Sorry but this is part of the problem.
I tried your method with using Pepboy/Napa and so on.
My emissions went up over 300 when I used their products.
They do not know which emission product to give you so they pick.
If you are in dallas you can call:
Irving Ford dealership at (972) 256-5551
or
Grand Praire Ford dealership at 972-859 -5400
Best investment in my truck ever are listed below:
O2 sensor $84.00
EVP $34.00
Power steering switch $20.00
TPS $63.00
This inculdes tax.
truck runs like a bat out of hot soup..
Sorry about this.

Today, I again am a man !!! I PASSED!!!
I've been out of town for a week, but today ( on the 15th day since the initial test) I have passed, with flying colors I might add.
My results were:
25 Mph Test
HC: 16 - old: 756
CO: 0.03 - old: 2.93
NOx: 243 - old: 1171
15 Mph Test
HC: 45 - old: 874
CO: 0.03 - old: 6.56
NOx: 513 - old: 486
As you can see a BIG difference.
I think the Cat Converter, the fuel pressure regulator, and replacing the 02 sensor ( a second time after the Cat install) solved the problem.
I still have the code 34 which I will address, but today I can drive around town and not look over my shoulder with each corner I turn.
This website is a GREAT asset to any Ford truck owner. I was at Barnes & Nobles last night and was about to purchase 2 books on
Ford Fuel Injection and Electronic Engine Control 29.99
How to Tune and Modify Ford Fuel Injection $19.99
These books had great information on troubleshooting codes. I think I will still purchase them and add to my "repair" library. I really liked the latter. Of course I read most of while sipping a cappaccino in a big lounge chair.
Thanks for all your help and advise.
Now I can complete my shed / workshop I am building and concentrate on getting my tranny fixed ( feels like it lungeing into gear when decellerating). So it's back to the tranny shop
