not sure if this is the right forum to place this in but i was looking for a lil help in finding out why it is burning more fuel after a rebuilt heads replacement

i got it from another guy that swaped in a d15 j-spec and p-28 ecu well it ran fine till the headgasket started leaking, well i took the head off got it rebuilt and slaped it back on with a new hg kit and water pump,new oil + filter radiator fluid, t-stat, spark plugs, cap and rotor

imma change out the injectors 2mmorow but would like some insight on what it could be

Did you also replace the plug wires? Have you checked the mechanical and ignition timings? Any CEL codes?

yes i changed the wires theres no check engine light and i assumed its on time since i put it back together per the haynes manual but imma get a timing light tommorow and do another compression test

but other than the bad mpg's it runs fine

o sorry it seems the exhaust got louder like a blown muffler so imma check the o2 sensor cat and muffler

Former User

Does the CEL work?

Do a compression test on each cylinder.

you probably wiped out ur o2 sensor when the head gasket blew.
