I have a toyota camry 3.0 with 180,000 rebuilt tranny new platinum plugs and wires and after I drive my vehicle for more than 2 hours I get loss of power. Then once I park the vehicle and rest it over night power is less than what its supposed to be for a V6 but power is o.K. Ive changed TPS, tune up, oil change, I'm getting code 52 and 14 from the obd1 but codes don't stay on all the time. At certain speeds car also bucks or engine surges everyone in a while.

At certain speeds car also bucks or engine surges everyone in a while.

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)

Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires
