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!
