Car runs like crap, spits, sputters etc! HELP

[supradaddy0803]

Ok I know this is gonna sound a bit silly but when I first got into mark 3's I did it and I have worked on cars since I was about 12. The thing was back like 1999 I didnt have internet access and I was stuck in the military in South Dakota with no reference to anything 7MGE so when doing the timing belt I got it 180 out. Sad thing is it still runs fine at idle but when you push the gas it will die real fast. Sounds funny but it will run beleive me I have seen old fords and chevy's run 180 out and they sound like crap. I am just saying this since you did the head gasket maybe check it because it shouldnt throw black smoke if you retard the throttle the computer shouldnt let it. I know you are running out of options might as well a shot in the dark it is a none interferance motor or so the toyota techs tell me so you wont bend anything. And by 180 out the cam marks were pointing down instead of up and the crank mark was pointing at them at the zero mark. But it is worth a try with what you are describing.
