Hello I watch a lot of your videos and now I’m getting to like Toyota a lot more lol any how I just got a 2002 sienna with 108k miles and it has no power really it starts fine but has no power if it’s cold it will rev over 1k them when wormer normal but if I try to rev it nothing I’d have to play with the peddle and it will start to rev higher an I can get it to rev all the way up So I took two of the o2 sensor out Becouse it’s got two codes p0135 and 155 soI take them out and I feel it has more power and I can get it to rev a little quicker but slightly of both so I go ahead and drop down the fuel tank and put a new a new fuel pump motor in put out everything back together and it the same deal and I feel the fuel gage is also a little off


I think the Catalic converters are

Clean the MAF sensor and throttle body and change the air filter. If you still have the same issue, check the cat. The 108k miles is nothing for the cat to clogged up though.
