So i need help getting my EGR out and cleaned to try and pass smog asap. My Nox reading is just a little over the max allowed, I've already replaced plugs/wires, new O2's, air filter is K&N, PCV is new, and i Just cleaned the MAF and ran some sea foam thru the Vac lines and in the gas tank... I'm running out of ideas, and the cheapest thing to do now besides a new cat is clean the egr out to rule out the cat as the problem. HELP! im in diamond bar, anyone near me who could help work on the egr it would be awesome. thanks!
