Thanks, I already changed plugs and wires. Coil is the only thing I haven’t checked yet

Sounds like the same problem I had and reported to Toyota they refused to admit it was a frequent problem. Evap canisters replaced, exhaust, ended up being a sensor wire from the gas tank to the front of truck. (codes po441, po440 and po466).

My 04 runner kicks the Trac and vsc off for an o2 heater code.. I suggest you go to your nearby Orileys or checkers, use their scan tool for free, and let the car tell you what the problem is…

I have heard in the forums of this happening and it was the O2 sensors. Worth a check

After replacing plugs and coil packs it turns out mine was a leaky head gasket dripping coolant down on to the cylinder at cool down and causing a miss fire at start up. 05′ 270K

Get the codes read… This will be nothing more than a guessing game. No one here can say with any certainty what the problem is without a code.

It’s your water pump… It’s starting to leak and its dripping down on the sensor for the oil pump…. So one of two things will happen. your water pump will fail and snap the timing belt, or the water will find its way into the oil and cause your motor to become damaged internationally. I just had this happen

There is no antifreeze in my oil. I haven’t been leaking any antifreeze

Well then your oil pump might be going out… When was the last time you did a timing belt?
