Need help. The check engine light was on and I got the code read at Autozone. P0402 was the code. After research I found that the best choice was to replace the dpfe sensor. Now the car ran rough (lose power, hit the gas and car would want to stall) low on gas and would sometimes kill. After I replace the sensor car seemed to run ok and the check engine light went out. Now it starts acting up again. Sometimes at about 1/2 tank. I'm getting tired of filling up every other day to avoid stalling and the shakes. I'm leaning toward a fuel injector, but I'm hoping someone ran across this or knows more. Thx!!
