Problem With Hesitation

[DARKTALONTSI]

i just replaced my tb shaft seals and no longer have a huge hesitation problem but i still do have this thing that when im ruising or something i hold the gas to 3000 rpms it holds but fluxuates it doesnt stay steady and also when i first start it sometimes it the idle would be everywere and the car would want to die if i didnt give it gas but once it warmed up its perfect....that was before now the idle is perfect but sometime it just wants to die when i come to stop or something until it warms up.....i have new plugs, wires, o2, fuel filter, oil filter.....i dont know what else it could be im quite sure its not a boost leak since it drives 100 times better, my alternator is ok the lights dim out with the signals and stuff but its still ok i believe, could an exhaust manifold to turbo leak cause this?.....what about bad tps.....i can only think about them 3 things...help please

im having somewhat of the same problem. when my fans kick on my car dies out. i was told the check or replace my tps and go from there.

ive searched around but cant find something like whats happening here ...but looks like it could be the ics, tps,cts or dirty egr and i also saw someones car was acting like this because of the alternator going bad since sensors need to c full voltage but my battery and alternator it charges the battery to 13.8v but still my lights dim when i use the turn signals....any one had any of these go bad on them what symptoms did u get

Im Still Clueless Also Every Other Time I Start My Car It Acts Like When The Maf Is Unplugged Rpms Going Up And Down Wanting To Shut Off But Picking Back Up Until I Drive It For Like 2 Minutes Then Its Normal

when I had this problem it was the tps.

ANYONE HAVE MORE INPUT TPS IS $158....SOMETHING else i may consider adding to this total?

have you checked for any leaks after the tb? also if you took your tps off the tb did you make sure it was properly set up afterwards?

im still stumped....i tried to adjust the idle but if i set the rpms to be around 750 in drive as soon as i put it in park they jump to like 1400 i dont know whats going on i screwed the biss screw all the way in to drop the rpms and tried raising them by adjust thing the plate with 2 screws that hold the throttle cable....i just installed a new pcv but same thing
