89 tbi 5.7 running poorly no power at low rpm or half throttle

iv got an 89 fullsize chevy with a 5.7 tbi and 5speed with ceramic clutch. Its been runnin like complete **** latley and im stumped of figuring it out. Started pullin my hair out yesterday after if left me walking twice in 1 hr and seriously thinkin bout throwin the tbi and intake away for a carb. its thowing several codes a 12 15 33 34 32 The motor is a reman replacement and idk how to find out if its still under warrenty. It is real doggy around 1 to 2.5 grand and seems like its got a dead spot in throttle. runnin down highway it will stall out and stay stalled untill i take my foot off gas then its fine untill i push petal halfway it will stall again like i shut the key off. Also at the same time it stalls my tach will stick and my temp guage goes crazy. I apriciate any help anyone can give me. If there is anything else you need to know ill glady post
