Hi all , bought a 2002 3.0 Patrol wagon 4 months ago , intermittently the check engine light comes of with varying degrees of power loss , goes great for 2-3 weeks then plays up , when it's going well it flies but when it plays up it barely pulls its own weight along , no rhyme or reason to it - rough rds or freeway . Have replaced MAF sensor , cleaned ALL earth leads , removed battery leads for a few hrs , changed 3 fuel filters - 1st 1 had a tiny bit of water in it but last 2 fine . Put scan tool on & brings up P7 fuel injection feedback . Local fuel injection mob want to put a pump on it but I'm not convinced & at $3000 I want to be sure . Im told a few different things will bring up that fault code ? Any help welcome as I'm close to burning the thing .
