Hello all, I am a new owner of a 94 Lexus ls400. I bought the car from my brother about a week ago and he says it ran well for him. He recently changed the O2 sensors which cleared a CEL that he had. However he wasn't driving it much and it had been sitting for awhile. When I got it and drove it home it seemed to run fine. But about 2 days later I have the issue where if I step on the accelerator any more than a little less than half it will stutter or just flatline the engine to about 1000 rpm. I've been reading through some of the forums on this site and seen people talk about the problems with the ECU capacitors so that was the first thing I pulled. It had looked like someone had gone through that process before because some of the clips in the glovebox were already missing and the ECU looked brand new inside with no sign of leaking caps etc. Then I moved onto replacing the fuel filter which did look really rusted and old but that also did not help. So now I am moving onto the tps sensor. At my local AutoZone the cheapest one is about $100. But I have seen some online for as cheap as $12 up to about $30. So my main question is there really much of a difference between these. Some of the cheaper ones seem to still get good reviews being put onto other vehicles that they'd fit (Toyotas Volvo's etc.) Also if anyone has any other insight on what causes this issue would be great. The vehicle has 245k miles and runs perfectly otherwise as long as I'm light on the throttle. Sometimes I will get a quick flash of the Trac off light when this happens. Not always so I don't know if it's just coincidental or not. Thanks in advance for any input anyone has. Eric

ok so i have a 98 SC300. at the stop light i hit the gas and the car did nothing. checked the throttle cable and its working fine. put it on the scanner and got p1120 throttle positioning sensor. so i changed it. the car ran fine for about 20 mins. then bang same thing.... you step on the gas and nothing happens, it doesnt rev the rpms do not come up even a little. nothing happens, if i turn the car on and off a few times stepping on the gas then it goes for a few mins but then it happens all over agian... i have heard of the throttle body getting gummed up but i put TB cleaner in it and no change. any help will be wonderfull thanks so much.

Changed the starter in my ls400 at first it ran poorly with an engine code 41(tps) I had one, so I installed it, the code is gone, but the engine only idles, smoothly, but just an idle. It will not accelerate at all. I first thought I have a vacuum leak, but do not see. or hear one.. I'm kinda lost to where to look now?.. Thanks in advance, Skip btw. there were no codes before the repair and the car ran awesome!
