94 Ls
Here is my 94 Ls, won't pass smog.. this car has 134k miles.. the only part that didn't pass is the emission test... i did sea foam hours before the test, thought it might help pass it.. when i took it white smoke started coming out and it was a lot.. Do you think the sea foam might've caused it, I smog test soon? And I already replaced the O2 sensor.. i don't know what else to do about it.. Need to replace catalytic converter? it's also on some aftermarket exhaust but when i bought the car the precious owner gave me the stock one.. you think it might help if i replace it? I'm thinkin that there might be a seal leak on the exhaust manifold.. not sure.. I need help or some tips I could use to help me pass smog.. This is making frustrated because i don't know what's making it not to pass smog and i'm running out of options. Thanks
