I had the exact same problem described in this thread, except for the error code. Anyway, the issue got solved before the throttle body gasket I ordered arrived. What fixed the problem was simply to pour octane booster on the gas tank, that's it. I live in Costa Rica, Central America, and the "premium" gasoline around here is not of the best quality (to put it politely, actually is kinda crappy) so perhaps the octane booster cleaned something in the fuel/injection system? What do you guys think?

Thanks...

the damn thing is back again !!

Last time i didnt change the gasket, but this time i will!!!!
Does this is the good gasket ?



I cant disconnect the connector. I squeeze the boot on top and twist the part under, it make a 1/4 turn but nothing much.

Its a rainy day and i work outside, i will try tomorrow

Also,

Last time i've changed the thermostat, i've also changed Water Temperature Sensor. A month a ago, my engine overheated! So i did a headgasket job + resurface the head. I forgot to change the water pump. SO i will do this in 2 weeks since, i have coolant leak near it. At the same time, i will change the water housing and gasket on the TB.

I want to know, Does an overheating can effect the Water Temperature Sensor ? Do i have to changed it if i've already put a brand new 3 month before the overheating ?

thx
