A little depressed... emissions testing sucks...advice?

So, as some of you know I have a '94 coupe. originally a V6 base model, that I have completely transformed into the 5.0, 5 speed monster that it is.

Problem is, I live in an emissions restrictive county.. something I did not consider during my decision to swap. The car has no catalytic converters, no charcoal can, no EGR whatsoever, and smog pump bypassed. obviously the check engine light is on.
I could use some REALISTIC, HONEST, HELPFUL advice. I will not go to an inspection shop and pay more money for both of us to be fraudulent and breaking the law.

I am very attached to the car, but am sensible and responsible enough to do what is necessary.

---------- Post added at 02:48 PM ---------- Previous post was at 02:42 PM ----------

Let's say I obtain and hook up everything perfectly (realistically about $600), get the check engine light off etc, what are my chances of the 5.0 passing emissions as the 3.8 V6?

It has the following in it:
Professional Products Intake Manifold
Cobra/GT40 Heads
E303 Camshaft
BBK Shortie Headers
BBK 70mm TB
BBK CAI

stock 19# injectors, MAF, etc.
It's the E-cam in it that worries me...

I live in California. The most unfriendly place for cars! The E cam is carb (California air research board) exempt. My car passes smog here with the e-cam in it flawlessly. I wouldn't worry about the cam at all. My car passes smog actually easier than without it. As far as the v6 and the 5.0l being able to smog with the same numbers is something I can't answer for sure but I wouldn't stress about the cam at all.

Thanks for the input. I'm sure the v8 puts out higher number than the v6 just don't know much.

I would definitely agree. I think you will be fine with all the smog equipment back on and in proper working order

Could it pass as a show car, not a daily driver? They don't do testing here in Indiana. I was wondering if they some type of designation like that.

That's really encouraging. So emissions requirements for V6 and GT are pretty close then?

I'm not familiar with Texas emission regs but your car should easily pass emissions the only thing you have to make sure of is if they do a component inspection make sure you have everything the car should have just go talk to an inspection guy and they will tell you what components you need to have

We have a shop my family regularly goes to, between work trucks and personal vehicles. The owner has been understanding but still won't pass a car with the CEL. That will be the goal.

My sticker expired yesterday, so I'll have to borrow a car until I can figure out what to do exactly.

What is throwing the light? Just cats/emissions systems?

I figure it's just a mater of time before they bring it back, so I've been planning my mods accordingly.

I honestly haven't ran them in a while. I ordered two new o2 sensors and when they come in and get installed I'll run the codes and see what all I have going on.

im hoping they will eventually get rid of the old school dyno tests. on newer cars they just hook up to the obd2. since there arent as many cars left prior to ob2 some states are beggining talk of stopping the old ddno testing. oh btw they have always done this in my county.

I remember the stickers in the drivers side windows, but that's about it. I think I was like 12 when they stopped. I'm not sure why.

So, with the new method, your good if you aren't throwing a CEL?

Well I'm not sure. Definitely can't have a cel. And they might still connect to your obd2 and even hook something the the gas tank.

IF the CEL is from the EGR being removed, buy (eBay) or make (see diagram) an EGR Eliminator, that will turn off the light. If they do a sniffer test, then run out all of your fuel and put in a just enough E15 to get you there, through the test and back home. The alcohol burns cleaner than gasoline.

Alright, thank you for all of the opinions. I've decided I'll stick it out and gather all of the emissions components to get this thing passed. Luckily I'll be able to drive my sister's car until then.

Will update this thread.. keeping fingers crossed.

Tune up so far:
MSD Cap&Rotor
Motorcraft Copper Spark Plugs

Ford Racing 9mm wires will be ordered.
I already ordered two new Bosch O2 sensors; AutoZone had none in stock. They should come in by end of today. A new fuel filter is sitting at home waiting for me to install.

I'm talking to a couple people parting out 94-95 Mustang GTs.
It seems most emissions stuff is already gone..

Man, that sucks. Maybe you can scour the local scrap yard so you don't have to buy those parts brand new.

Another thing that helps if there going to do a tailpipe test is a fresh oil change. Here in NC they don't do Dyno testing only vehicles 96 and newer get hooked up to the computer and the computer just looks at the readiness monitors to see if it passes. 95 and below is just a simple safety inspection no emissions

I'm not positive on what the cutoff is for safety/emissions tests. But I do know that last year (as a v6) it was the whole tailpipe-probe-on-the-rollers test. I'm 87.5% sure it's when the vehicle is 25 years old or older it's safety only.

Re: A little depressed... emissions testing sucks...advice?

I installed the new O2 sensors and new fuel filter.

After, ran the codes and received the following:
121 - TPS out of range
311 - AIR system not working - Single, Right or Rear HO2S
314 - AIR inoperative, Left or Front HO2S
332 - EGR did not open/respond during test or if memory code, did not open intermittantly - EVR or PFE
552 - AIRB solenoid?circuit failure
553 - AIRD solenoid/circuit failure
563 - High Fan Control (HFC) circuit failure
558 - EGR vacuum regulator solenoid/circuit failure - EVR or PFE or Solenoids
542 - Fuel pump open, bad ground or always on


About 121 -- does this means the TPS needs replacement, or adjusting?
About 563 -- I'm guessing because I am using the original V6 fan/shroud..
About 542 -- Could this have been caused by my changing of the fuel filter?

I'm resetting the codes and running the test again in the morning.

You might be right about the fan and shroud from your V6. There should be a fuel pump relay somewhere and maybe it is stuck closed. On my 87 GT, it was under the driver seat. I had to take a screw driver handle and give it a little tap once in a while until I replaced the relay. You could clearly hear the pump still running after turning the key off, then stop after the little tap on the relay.

Maybe this link would help for your TPS...
