Re: 1994 Camry vacuum modulator filter
Similar issues on my '94 4 cyl w/190k mi, although nott throwing any codes. Just high NOx readings and failing smog. Had to replace the EGR filter which was around $85 or so. NOx came down, passed smog, etc. Mechanic said that it is hard to really clean the filter. Best to replace it. If you talk to dealer's service dept, they say that just replacing the EGR filter, not the whole unit solves about 80% of the issues. I also replaced my original fuel filter which was original. Let us know what solves it for you.
