I have a 96 civic ex which had a blown head gasket and was overheating, so i installed a jdm 1.5. The problem still occurs. Now i narrowed down, i have new radiator, thermostat/ hoses belts. I also noticed the check engine light doesn't come on when ignition is turned on so i checked the fuses and my abs fuse box is getting power exept for the slot for check engine fuse so i am gonna get a new abs fuse box, then i will check for codes.
One of my friends said it might be cpu, but if anyone has any idea please let me know thanks
Ps: oil looks good, no bubbles in radiator when it starts, and cooland lines and vaccum seem to bee right.
