Hey all, I found a couple threads on this but still didn't really answer my questions.
I've got a vp 3.8 in my Toyota surf, and it's spitting out a heap of unburnt fuel. If I tow a trailer it gets absolutely coated. The spark plugs get fouled up pretty quick, and after the engines warm and been driving on the highway it coughs and splatters, then stalls when going to lower revs. I'm using the surf's in tank fuel pump which could be putting too much pressure in the fuel rail, but that shouldn't matter with the pressure relief back to the tank? I've got a "stage 3 memcal" ECU, but I have tried a standard one and the same thing happens. Anyone got ideas to fix? Was thinking a fuel regulator before the fuel rail? Cheers in advance
