Hi. First post in the forums. I've owned a 95 Civic EX. AT and a 99 Civic EX AT but recently I purchased a 92 Accord with a F22A engine. The car sat at my uncle's place for about a year. After I purchased the car for next to nothing I took it to get registered and smoged. The car ran started and ran fine for a few test drives. Engine sounded like it needed a little bit of timing work done. And I could hear a faint constant high pitch sound. After taking it to get smogged I got a "Gross Polluter" . I was a bit crushed to find put a car I thought was sound, coming from my uncle, would turn out so bad.
Smog read outs: (the maximum value to pass smog/my Accords readings)
15mph - 1679 rpm, %CO2=13.2, %O2=1.2, HC (ppm) = 81/71, %CO=.074/1.63, NO (ppm)=554/2183!
25mph - 1791 rpm, %CO2=12.4, %O2= 0.9, HC (ppm)= 91/112, %CO=O.62/2.12!, NO (ppm)=511/1479!
I spoke to a mechanic friend of mine and was able to give him the whole story. He told me first I am dumb for not doing an oil change and fresh tank of high octane for a car that old, then he listened to the engine and pointed out a few things: I have a vacuum leak (much louder than before I took it to get tested) and the fast idle controller had some nasty looking hoses for the coolant intake and outtake, this would explain the high idle (around 2k) and the vacuum leake could explain the plorblem with the fuel evap control failure. He also tod me to get new plugs and maybe wires too.
My question is, with smog read-outs this high, will fixing the above problems along with fresh oil and gas and coolant be enough to pass smog? Could I have another problem or things to look at?
Note: there is no white or black smoke coming from the tail pipe at hot or cold temps.
