problem on a GE, fuel related.

[87hilux7mge]

well i got some news for this one. he did a compression check, 160 all the way across, except #6...zero compression. checked the cams and valves, one of the #6 exhaust valves was stuck open and spit a shim out, lodged it in the bore and stuck it open permanently.

before that, he had cleaned his plugs and no improvement.

i had the same suspicions about the fpr or map. since weve checked everything else, excluding the map. i also suggested he reload his tune, but he was hesitant to do so. im still firm in that thought.

basically he needs a new exhaust cam and to fix the head, hes pretty sure the bore is fixable so now hes part hunting.

anyway, ill update as needed, but im pretty sure the faulty map is a good possibility as well as the tune screwing up itself..
