Therefore, I head over to a mechanic recommended by a friend to check my timing. The mechanic checks the timing and confirmed that it was indeed 9 btdc. I ask him to correct it, but he was only able to get 23, because now the distributor adjustment was maxed out. He suggested that I am off a tooth or my timing chain is stretched. Also, he assured me that the guys at the smog station that I went were not messing with me, because he knows them. He give me his business card with a written note on the back addressed to the 2 smog techs that he adjusted the idle to 23. Therefore, I go back for the retest and pass.That was 2 years ago and I was never able to figure out how the hell my tming could be at 9. I posted on the forums and most people say... hey it happens just retime the motor.
So recently, I finally figured it all out. My cars idle was oringally stuck at 1200 rpm. because my idle screw on the IACV was stripped. Last week, I bought a timing light and got a iacv with an unstripped adjustment screw from a junk yard. After the install, I adjust the rpm to 700 and decided to check my timing. It came out to be about 31 btdc, which really had me confused for a few minutes. The distributor position was at full advance from the last time it was adjusted to 23 btdc to meet the smog requirment and was never touched from that point. I then realized that it was because my base idle was changed. I adjust the timing back to 20 and the bolts to distrubutor show that there is plenty of adjustment room left.
So what I think happened at my last smog check was that smog tech didn't even check my timing for the first test. Maybe the guy forget or was being lazy to save time.
It is possible the smog tech didn't want to check, because the emissions portion failed. However, I don't think the smog tech knows the emissions results until all checks have been entered and the computer ouputs the paper work. Also, it never occurred to me that the idle being off would affect the ignition timing.
