Hi everyone,
I recently did head gaskets and valve job to my 87 Pathfinder V6. Broken timing belt destroyed the valves so I removed heads and took them to the shop to get new ones. Everything is assembled now, but Pathfinder can't go over 3000 rpm and has a bad rough idle. Loss of power is also present.
I have checked timing. I'm pretty sure I have crank and cam timing synchronized. I also checked ignition timing (distributor) and stuff.
I'm getting code 12, that is air flow meter. I cleaned the MAF sensor without luck.
I need serious help. Is it the MAF sensor, vacuum leaks or off timing? Thanks for your time.
