ENGINE PROBLEM ON 3SGTE SW20 MR2 =(

Engine seems to be choking/struggling once in a while that just happens out of nowhere. I step on accel. and there's no response to the throttle and it seems to just choke hard and feels like it's flooded. Kind of like running out of petrol feeling and the revs will not rev freely at all, even in neutral. It can happen during freeway driving, and it can happen on take off, it happens whenever. Sometimes it can happen once or twice a day, sometimes it doesn't happen in a whole month. Sometimes it goes on for about 5 seconds, sometimes it goes on for about a minute. I use high grade premium fuel. I've heard from others it can be sooo many things such as dizzy cap, ignition leads, fuel pump & lines, fuel filter etc etc, which makes it hard for me to take it to a mechie since i'm paranoid about them making a list of crap up and overcharge me.
I got error codes 41 and 51 when i did the engine ECU error code diagnostics
Checked up the BGB as is elaborated as followed:-
41 = Open or short circuit in throttle position sensor (TPS) signal (VTA)
51 = No IDL or A/C signal to ECU with check terminals TE1 and E1
Now my questions are ..
Code 41 - How would i go about fixing this problem? I've had a choking/struggling problem that i've been trying to find out for ages. Symptoms are .. like running out of petrol, no matter how much gas i give it, it won't move, like it's struggling or choking. Could this code 41 diagnosis be the answer to this problem?
Code 51 - Could this code 51 diagnosis be the answer to this problem? And what's IDL & A/C stand for? I'm taking a guess that A/C = air con, but i'm not sure since i'm a hopeless mechie.
I've changed the sparkies, leads, rotor button and dizzy cap, and even the TPS. Now the codes 41 & 51 are gone since i changed the TPS and i have no more error codes on the ECU.
'WAS' happy for the 2 or so weeks that i had no problems, but suddenly the 'choke' sprung up again Re-setted the ECU and still not logging any error codes, all clear.
I don't think it's fuel related (but i could be wrong), there's no smoke or any pop/bang noises, it feels more like somethings holding or jamming the accelerator cable, but it looks fine when i rev and a mate is watching the engine bay.
Anyone know what else i can try? Could it be O2 sensor? AFM? ECU?

Anyone with any solutions is greatly appreciated.
