2 issues, please help

one of the problems started a few days after me and john replace my injectors.

the other one has been doing this for the longest.

1st problem:
when the speeds exceeds 40mph and in 4th gear.
you let go of the gas the rpms will bounce up and down a few times then hold it's ground.
sometimes she does and other times she's fine.

the 2nd problem is when i reach up to 45mph and i've been driving for awhile the t/c locks/unlocks a few times then lockis and stays till i let go of the gas.
this issue is solved by me shutting her off for a second or so...does'nt matter how long or if i park her and leave her running for a few.
the problem goes away but comes back if i'm driving for a very long time.

idles is fine,acceleration is way better than before the injector replacement no missfires, no check engine codes t/c codes i'll have to check. tranny fluid level is fine. color is fine (even though i'm due for another change).

btw, it's a vg-a

1. Youre driving with warmed tranny, gearlock is ON? What is the rpm, where does it jump, where does the "let go" rpm level? ... how about a video?

OD off has no problems? How is the TPS, have u tested it.

Do I remember right; your tranny was slipping at one time?

2. Driver door sw adjustment is out?

the 1st problem has nothing to do with the tourque convertor. but if the speeds is above 45mph the engine rpms will bounce 200-300rpms and it seems to happen when the rpms are around 2k.

and now that you metion the checking the tps.
there has been times when i'm crusing with the torque convertor locked and i hit a bump it'll unlock then lock.

and... lol.
i think you miss understood the 2nd one.

i was talking about the tourque convertor lockin and unlockin.
when reachin 45mph or more and i've been driving for awhile the t/c locks/unlocks a few times then lockis and stays till i let go of the gas.
this issue is solved by me shutting her off for a second or so...does'nt matter how long or if i park her and leave her running for a few.
the problem goes away but comes back if i'm driving for a very long time.

and yea i was the one with the tranny issue.
it was'nt slippin, hell i don't know what it was doing.
all i know is when it was in comfort mode it would shift like that.

but now it does'nt do that.

i've yet to do the resistor mod (plan on doing that on my day off)

Yes, miss understanding is a built in feature.... try to endure.

At least vibration related problem, could explain all: Broken wire, loose/bad contact. Check the ctrl harness to the tranny, tighten/grease connectors. Hope youll find - and the intermittent cut is not in the solenoid assy.

Speed sensor maybe ? dying on top of that.

All starts from checking charge voltage at TCU pins.

okay the locking/unlocking of the torque coverter problem was solved.
i have a stacked tranny cooler.
it was behind the bumper so it was'nt gettin the proper cooling.

so today i put her to the test.
went on break had her runnin. went to pick up tires for my job. went to get my brother. spent about 1/2 hour to an hour cleaning out my car while she was still running. went to pick up my sister. stopped at the store. took her out on the highway no problems!

before getting on the highway i checked the cooler: warm.
after the highway drive: warm.

so now my unstable idle around 55 mph...i'm thinking it could be the egr valve?
is that possible?
