I already check for vacuum leaks before replacing the FPR and found none. The o2 is new and I cleaned the MAF when I got the car and did a bunch of other preventive maintenance. Looking at the MAF data while the car is running the output looks ok and goes up and down pretty smoothly with the RPM although I dont exactly know what to look for. Its a northstar MAF as well
