radiator question and my car is still screwed up after a new motor!!! 2000 G20

[stv]

Ok, I dont know who all has been reading my problems, so to make a long story short, my car overheated, cracked the head so I had to get a new/used motor. I patched the crack on my radiator until I get a new one and when I start the vehicle it sounds great, when I give it gas it almost dies or does die, then after a little while after playing with the throttle it will rev up, but if I let it idle and then hit the gas, it goes back to the problem. The only code that was thrown is egr temp sensor, which I replaced and it didnt make a difference, the same code is thrown sometimes, other times the CEL isnt on. The only other code thrown was that my #2 gear (ATX) is not responding, but I doubt that is the case, I believe it is being thrown for another reason. Any thoughts? and my radiator question is, what other vehicles (y,m,m) have the same radiator? Thanks I need help!!! 2000 G20 sr20

i would be looking into your MAF sensor...had an infiniti in the shop doing what yours is and we were having all sorts of problems with it bogging and dying..turned out the maf was toast..

Make sure the EGR is clean. Could also be the MAF, TB, or the TPS. I'd start by cleaning the EGR and TB/IACV.
