Thank you all for the input. I suppose I should address the O2 sensors, it has been fine for 4 years, but I understand it should be addressed. I swaped the coil, no change, fuel pump 2 years ago, cap and rotor was done 2 months ago with plugs. I tested my ignition control module two months...

When I was doing the head gaskets, I discovered the heads were cracked, I hear this is common due to a higher sand content in the Mexican made castings. So I replaced them with new cast heads, sorry I forgot to mention that. I replaced the injectors at the same time with the updated unit...
