Emissions System

Hi, I have a 1993 F-250 5.8L that does not have a emissions system hooked up. I need to go for emissions next month and I am wondering if I could run a hose from the smog pump to the AIR injection tubes with a check vavle on the two tubes. My question is would I pass emissions with just the AIR injection tubes hooked up and none of the other emissions stuff??

Thanks,
Brandon

Welcome to FTE!

Go here and call them.

CT Emissions Program - FAQs - Fees


It looks to me like you have a sniffer test, not a visual. BUT you need to confirm that.

Do you still have cats? What else has been changed?

Others may come by who live in CT and advise.

Others may come by and suggest you move to a state where they don't test or other "helpful" BS.

Between the DMV and others in CT, you will get your answer.

Thanks for the warm welcome!

I am definitely sure that it is a sniffer test.

I still have the one cat on the truck. I have all of the parts, I believe, for the emissions system in my garage. They were taken off by the previous owner because he tried to do a smog pump delete and didnt do it correctly. Now I just wanted to see if I i could just hook up the smog pump to the air injection tubes and not waste my time trying to put the whole emissions system back on. I am just wondering if that will push enough air through the exhaust to lower the CO and HC levels while idling.

Thank you for responding to my post!

Worth a try. Be sure to set the ignition timing where they want it for smog, maybe a little fuel additive, fresh oil change, pcv working right. Those will help with NO and HC.

I will definitely check the ignition timing. I will also check the other things too. They sell a emissions additive you add to your fuel and it is a guarantee pass and I will probably try that as well.

Thanks for your help,
Brandon
