Just keep in mind that if you replace (and possibly if you rebuild) the car won't be drivable until you get it reprogrammed for your key's immobilizers.
I would be cleaning out the VVTi oil filters and testing cam sensors before getting to the point of ecu replacement.

I have done that, even replace the cam sensor on the driver side as the code said bank one. I also tested the ocv by applying 12v to it and the plunger does move

rebuilding the ECU (replacing the capacitors) does not affect the ECU's programming and therefore does not require reprogramming or in any way upset the immobilizer circuitry
If ECM bad will i be better off replacing the caps etc or find another ECM?
If you replaced the ECM, you would, as Pure Drifter pointed out, have to reprogram the ECU, which is a pain and an additional expense, so rebuilding is always preferable, except in cases where leaking capacitors have actually damaged the circuit board irreparably.
And in extremely rare cares, another component in the ECU has failed other than the electrolytic capacitors or a power resistor, and that situation is normally not repairable.
How many camshaft sensor do the 98 Lexus ls400 have? Is it one on the left(driver) side timing cover and on the left side head? I only change the one on the head not the one on the timing cover.
it's not really on the timing cover and certainly not on the head, it's on the rear timing belt plate and there is one cam position sensor per side (left bank and right bank) for a total of 2 on the entire car.
Hmm when I look it up etc it say one on cylinder head and the other on the timing cover. The sensor on the cover go inside and will have to remove the timing belt cover to get it out

I can't think of any sensors on the head itself, other than the two knock sensors, but you won't be replacing those with less than 6 hours of work! - lol
Wait I think it is the vvt sensor instead that I replaced lol, so yeah the camshaft sensor should be the one behind the timing cover, and the harness stick out through the cover with a rubber gromet on it
