I went to get my smog check and failed. HIGH everything, first time my all stock 89N/A has ever failed. The tech said my timing was off so I took it right over to my mech straight from there and had it checked and it was on the money so Stay away from Ace Smog in Oceanside. Now it did have other issues, plugged EGR, bad O2 sensor, and a bad ICS and some electrical issues with the AFM. So I left it with my mech, then took them spare parts I had and they did everything including fix my valve cover oil leaks, do an oil change with castrol Euro 0W30, Wix filter, wix air filter and took it to the smog shop behind them and it passed with flying colors everything way low now. So a Big Thanks to LSI Automotive in Oceanside, CA. It's owned and operated by an Dewight, an ex Marine, a man of true honesty and automotive knowledge. The entire job including the smog check was only 659.00. I am one happy man.
