Thanks guys for the quick response.
Ed, thanks for the insight on the fuel filter so I won't need to check it because the acceleration is great and no hesitation. The engine runs smooth. Tire pressure is 35 or 36 pounds all around. Not stuck in traffic at all and mostly flat freeway driving. The car has 136k miles and the A/C is only on about 1/3 time. I'll put some injector cleaner in tomorrow.
Thanks John about the O2 sensor missing the exhaust gas that is bubbling into the cooling system. It is a very small string of bubbles though. I guess I will try one more bottle of head gasket sealer. Any suggestion on which one to use?
I am using Costco premium. The sign on the pump says less than 10% ethanol.
Jeff02, the engine runs pretty smooth and there are no computer codes. It just passed smog about 200 miles ago. Yes, maybe a vacuum problem. I doubt a timing belt issue. The compression is the same in 5 cylinders and the middle rear one is lower by 15 pounds which is where the leak must be. It's not in the limp mode because it performs too well and the cruise control works.
Any other ideas will be appreciated. I'll check for a vacuum leak and add injector cleaner.
