Wanted to send an update. I took it to a shop a week ago. they said the compressor was fine but the relay was bad. Apparently it is common in Toyotas. They replaced the relay and everything is working great.

Thanks for the advice. I did test the pressure on the low end with the compressor on and the engine at operating temperature.
The AC did stop working for me last night. I heard a slight grinding noise coming from the compressor. So I guess it’s off to to find a shop that can work on it.

Last week I had the carbon professionally cleaned from the car. It didn’t help so this week I pulled the head. I was expecting to see obvious signs of a burnt valve but it looks fine. I think I will still replace the valve and spring but I thought I would show you all what it looks like in case I am missing something.

Thank you all for the help so far. It is a 4.0. I ran the leak down test today. I couldn’t get a clear reading on the percent lost but it’s around 40%. It was a cheep tester. What I did find out is that I was leaking pressure through the intake. I pulled the rocker arms off and was still loosing pressure through the intake. I’m pretty confindent it is a bent valve or cracked head. But since I am a armature at this I thought I would ask if there is anything else I should look for before I pull the head off.

Thanks for the advice. I am going to run the compression test again this weekend and maybe a leak down test. The reason I am leaning towards the coil is because the head was machined and the valves were serviced within the that 12 months, also the timing chain, head gasket, and injector were replaced.

Thanks. I am working on this again. I pulled the plugs and didn’t see anything suspicious. I replaced them anyway. I also put a stethoscope to the injector and it sounded to be working fine. A compression test showed the first cylinder to be 95psi and 2&3 to be about 115. No change on wet test. The misfire happens around 1800rpm. So now I am thinking coil or fuel delivery.

Thank you Raistian and Eric. It looks like there was a change in the level from neutral to off, maybe 1/2 inch on the dip stick. I did notice that the fluid level was way to high (about 2 inches higher than it should have been). Any chance that could be causing the problem? Would it be worth pulling the pan off and checking to see if the filter is clogged?
