Xplosivo1 Posted September 1, 2014 Share Posted September 1, 2014 Any idea what might cause this? Driving down the road the little needle for the mpg gauge swings back and forth about 1/4 of an inch. I initially thought it was a vacuum leak, but I did a smoke test and it looks good. Also, the tuner I'm working with said the scaling for the intake isn't normal for a KSTech 73mm. I'm thinking it might be related. I've cleaned the MAF, checked the vacuum lines, and looked for fuel leaks. I'm running DW 1000 injectors and 65 fuel pump if it helps. Anyone else experience this?

Mike07LGT Posted September 2, 2014 Share Posted September 2, 2014 Is it only when you get low on gas? What about right after you fill up? 03 WRB WRX (RIP) 04 JBP STI (sold) 07 DGM Legacy GT (RIP) 12 OBP STI (DD) Link to comment Share on other sites More sharing options...
