wussup guys ...
i had a thread on here on how toyota broke my timing belt and replaced my headers and machined my ... i can't remember what its called anyway ...
over the past 4 months my GS 400 has been in and out of their shop trying to figure out what is wrong with it ... i got lexus involved and their mechanic can't pinpoint it either ...
this is the problem ...
when my engine is in normal running temp ... with the a/c off ... and on a complete stop in drive ... when i take my foot off the brake pedal ... my car thumps forward ... and not like a surging kind of a thump but like i'm driving over rails kind of a thump and its continous until i hit the gas then everything is perfect ... the guy at toyota tells me its a tranny issue ... but it didn't develop until my engine rebuild and another one told me its my brakes ... so why won't it do it with the ac on? .... is this an idleing problem?

also after an overnight sleep when i turn my car on there is alot of blueish white smoke ... i told lexus about this ... and they said that its normal after an engine rebuild and it will pass after 5000 miles ... well its been 6000 miles and its still there ... any suggestions ...
all help is really appreciated ...
