Potential emissions tricks, worth trying???

[jrichker]

They said the fuel injectors are all jacked up, said sometimes they stay open, sometimes they dont open at all. They wanted $150 to do a fuel injection system cleaning, but I figure since it's about $250 to get a full set of injectors I'd probably do that instead (Since they usually tell you they need to replace a couple of them anyway cause they're too clogged.)

Is there any way I could test them to see which ones are working. I know I could soak them in mineral spirits or something, but that won't really tell me which ones I need to replace. IS there a way to do this at home or should I just replace the whole set?

See http://www.cleaninjectors.com/process.html - $88+ shipping gets your injectors cleaned & flow tested. Great deal if you have other wheels to drive while the injectors are being cleaned.

That seems pretty interesting, only prob is I don't have any other wheels to drive while I wait. I've also heard that the internals of the injectors tend to start to wear out once they get up around 100-150k -- leading to one or two of them getting reclogged before long. So I'm thinking that my best bet would be to just get a whole new set. I was looking at mustangwarehouse.com, theyve got a set of 19# for $209.99, I think I may go that route. I also noticed they've got 24# injectors for an extra $10, I was thinking of upgrading H/C/I at some point down the road, would I be able to use these OK now if I got an adjustable fuel regulator? Could I just use the regulator to turn them down to a stock level?

I was also looking at these

I see they're not the usual orange topped ones though, would these work?

Have you actually failed the test yet? What didn't pass? What makes you think you will if you not?

 

[kdog_x]

Yes, I failed the test once with no cats. 3.9 on hydrocarbons.

Went and got some new cats, failed again. 2.6 on hydrocarbons

Got a full tune up, oil change, pcv, etc. ran some of that "guaranteed to pass" emissions stuff. car got worse, went back up to 3.7 on hydrocarbons.

Now I can't go back without some receipts from a mechanic, so I took it to a shop for an emissions diagnostics and they said they wasted an hour and couldn't even test it due to the fuel injectors sometimes sticking open. I figure if thats true it would definitely explain all the unburned gas. The emissions levels go pretty close to normal at high MPH but spike all over the place at low MPH. I ordered my injectors from summit today so hopefully I'll have them sometime this week. Gonna have to make up some phony receipts or somethin so I can take it again though.

Damn those smog nazis

Why make up a receipt, you have one. The emissions mechanic said you needed new injectors, you bought and installed new injectors. Here is my summit reciept. They were the cheapest stock replacements I could find. 100% true and shows effort to fix the problem.

How long does a car have to pass smog for, these mustangs are nearing 20 years old. They expect them to pass smog as long as they are drivable?

 

[kdog_x]

I checked the laws here near chicago, cars have to pass that are 1967 and newer. Which means I'll probably have to pass as long as the car is driveable.

As far as needing the receipts goes, they'll probably let me retake the test without receipts from a mechanic, however, if it doesn't pass the only way to get a waiver for a car 1981 and newer is to of had all emissions related repairs (at least $450) done by a certified mechanic -- thats where the phony receipts come in.
