Can I lower my fuel pressure to like 25psi to help pass smog. What else can I do?

 

well, yes and no - the car wont run well at all that low.

i lowered mine to 35psi - but i dont think it made much of a difference.

the biggest difference was the fresh engine oil, new s.plugs AND letting the engine warm up for 45minutes before the test - a cold engine wont pass smog as easily as a warm one...
