Hello guys! Got a question.
I have a '97 LX450 with about 90K miles. In went to a Test Only Smog Center yesterday and my emissions passed but the tester failed me on the test because according to him my timing was too advanced (18 BTDC).
My questions are: 1. What should the timing be to pass the CA smog test? 2. Isn't it the computer's job to take care of this timing? Is there anything wrong with my computer or some of my electronics? If so, which part is wrong and how do I correct this? Is there a DIY thread on this?
I've searched the forum and I can't seem to find a thread on this.
Thank you so much for your help.
