Few issues after swap complete

Few issues after swap complete
Hey y'all, finally got the yota on the road and put some miles on it. After about 30 or so I found only a few things. When I put it into neutral for example coming off the freeway. the engine begins to fluctuates its rpms, going up and down about 200-300 rpms every 2 seconds or so until about 20 mph it stops.
Also I noticed in the first 3 gears the oil pressure light goes on for a few seconds near the end of the gear until I shift to the next. It does not happen in forth and fifth.
The final thing is my temperature gauge does not react at all. only stays at cold. Heater works I will add tho.
Any help would be appreciated. Thanks guys

So I was letting the pickup warm up and noticed in neutral the oil pressure light would flicker abd I've the idle went down it still flickered. My idle is high, around 1100-1500, I haven't been able to diag that quite yet.
Drove it home from my folks place today, put 300 miles on it also had to take it up a pretty decent grade. Drove awesome.
When coasting and the surge begins I noticed my brake pedal world go in and out on its own in sync with the surge. Not sure If that's a coincidence or not.
But there's a little update after a good trip was put on it.

I've only got a dummy light, no gauge itself. just a water temp gauge that currently isnt working. Ill test the idle in the daylight. The brake thing going in sync with the surges is really confusing me tho.

Any codes? that's gonna be your biggest help.
I had to replace my tps twice before my swap would idle right also clean the IAC valve and TB plate.
X2 on the throttle cable routing was a pain for me.
Also check your vacuum hoses and get some hose diagrams off the interweb i got mine wrong the 1st time around ran like @#%$.

I will guarantee you either have a bad Brake booster or you do not have the check valve installed correctly to the booster, that is your surge and why the brakes feel weird.
At the intake from the booster, you should only be able to suck not blow back into the booster, if you can your check valve or you booster is leaking, if you tossed it they sell inline ones at most part stores.
That's an easy fix IMO

I checked if you have only a light then you should use the Small oil sender if you had a guage then you use the Large style sender they have the same plug on both.

Do you have the check valve inline with the hose for the brake booster? is it facing the right way? If you just have the dummy light leave the 3.4 sender for oil. If you swap to a gauge style cluster you will need to swap the oil pressure sender to a 94 3.0 sender so it will have the same plug.

So after checking what and everything what mentioned on the thread I still drop 500 rpms while braking. I honestly am completely lost at this point.
