Okay here's my problem. I have a surging problem when I clime up the rpm band. Acts like a honda v-tec. I've replaced the dpfe and It still gave me problems. So I bypassed the egr completely still does it. Replaced the spark plugs and upstream o2 sensor and I checked to see if the o2 cheater was working and it holds constant voltage like it should. I checked my fule pressure and it reads around 38psi. Also my car threw a code saying it was running excessivley lean p2195. I cleaned my mass air flow, and when I replaced my plugs they were kinda white so my motor has been running lean. My mileage has gone down alot and I replaced my fuel filter about 2 months ago. Also my sftrim is -15 to -19 so my ecu is trying to lean out the system. Anybody have any suggestions on what it could possibly be. [?|] [?|] [?|] [?|] [?|]
