Default Re: 90 wont pass smog

Me too, from the Holley generation and yup, I am getting an education. I will have to go back tot he dealer and get the print out. Unfortunately the guy I am getting the car from brought it to the dealer for the smog test. Found three bad injectors, replaced and flow checked the rest.
I checked the idle myself, brought it up to the 2500rpm required for the smog test and after a couple of seconds, engine at normal operating temp, the idle drops down by 400 to 500 rpm then immediately goes back up to the 2500rpm.
The dealer said that one or more of the injectors could beleaking down, so I asked a folish question, actually two, if the injectors were a suapect to begin with why didn't you run a leak down on them before putting the car back together? And, did anyone pull a spark plug and check it? I didn't get an answer.
I think another thing I can check is the air control solenoid valve and the canister purge solenoid valve. I know the dealer didn't do that.
Now that I have the car in my posession, I am going to have it scanned and see what it says.

Really appreciate everyones help, what the hell is a computer? Man what a cluster.

Thanks again and I will try to get the print out.

Tony
