Hey guys, my car has been bucking for a while and recently it stopped. After that, it started eating gas at twice the rate and there is a major loss of power. I had it brought to Lexus for a diagnosis and they said it came back with a code 041 throttle position sensor failure.

I ordered a TPS online and put it in yesterday. I adjusted it almost close to the old one's position. I got just some of the power back, but it feels like I'm driving a V4 now instead of a V2 a week ago. I am still burning gas like crazy and holding up traffic because its slow. Anyone have any ideas? Does adjusting the sensor's exact position really make that much of a difference? I tried turning it to a couple different positions but there didnt feel like much difference.

Just a little extra info, my car is so much louder now...it sounds like i just put on an aftermarket exhaust. There is smell of gas being burnt when I roll down the windows. Alot of the parts on my car are in working order because I just did a major maintenance run with many engine parts. I really need help because this is costing alot of money in gas driving to work

someone recently had the bucking problem. they said they changed out the MAF and it worked just fine. i only get the bucking problem at like 45mph and if i hold it there for a while. so i'm fine wit it for now.

peace out

that'd be me who had that problem. MAF definitely solved it. And my understanding of a MAF is it pulls gas from the A/F mixture as necessary so I'd look into that for sure
