trac and check engine codes
 

Hello,
I have a 94 ls400, with 150+k on it. I have never really had any problems with it, until now. The trac light stays on and when you give it just a Lil too much throttle, it will cut out. Until you let off the pedal. The check engine light comes on when it cuts out, then stays on briefly before going out.. I followed the directions on how to scan the trac comp, and the engine comp. The engine codes are, 41 and 47,(41tps signal, 47sub tps signal) the trac code is 47(tps signal) So, I replaced the tps's reset the comp. and wham o!!!!!! still exactly the same.... This did not fix the problem!!! it just cost $300 bucks for nothing! I don't know what to do now. HELP!!!!!!
Thanks, Frustrated & broke!
