I have a question about unhooking the injectors. If you unhook 2 injectors, shouldn't you disconnect those sparkplugs as well? I mean, if there is still spark going to those cylinders, but no fuel, will that not have a bad effect?

Way to go man! Glad it worked out for you guys.
Also wondering if rigging the air pump to stay on would help pass smog.

let me try something stupid.. i un hooked 2 injectors and let it run on 6 cylinders.. guess what passed with flying colors.. after i got the paper in my hand pulled the car out of the bay and hooked up the 2 injectors and laughed my a$$ off.. the next year they stopped doing emission testing in our county..

My uncle and his hot rod buddies told us to hook up a compressed air tank and tape it into the exhaust before the cat/sniffer(duh) rig a switch connected to petal, then open up the tank and hope. They said the compressed O2 will change the mixture of expelled exhaust and flush out.

If there is only air in the combustion chamber, and no fuel, there will be no combustion. You might generate a trace of ozone from the high voltage discharge of the plug, but that's not an emissions issue.

You would have to disconnect atleast one of your oxygen sensors to run in open loop & then disconnect 2 injectors otherwise the others will be running really rich since the o2's will make the computer compensate, disconnect one o2 & you're running open loop.

We didn't "tape" the hose to the pipe. Like i mentioned before you use a connection piece from an air compressor and tack weld it into the pipe before the cat. Check the post at the beginning of the thread it has a link that will help answer some more questions.

how did you tape a hose inside your exhaust pipe? and where did you put the tank. No body saw or heard the tank pumping out fresh o2. not calling bs but just ?'s [/QUOTE
