I left for work this morning and got about 2 miles away from home and the car would not get up a hill. Just started popping and backfire in the intake. I have replaced the fuel pump, filter, map sensor, pcv valve, crank sensor. The car has done this for weeks. Then let it sit for 5 minutes and it will start and run fine. Then the next day it will do it again. I had a code of PO171 before I replaced the fuel pump and filter, now no codes and no check engine light. When it does act up the rpm gauge wil be eratic up and down.
have the same problem?
