Hesitation of 87 Supra Turbo

pwrkick · 04-04-2009, 08:13 PM

well i just put a low miles used engine" 89 7mgte" , Ran good for a couple days seems to lack power and started to hesitate when turbo boost and it gradually got worse and worse so the things i have inspected and replaced were is new fuel pump, new fuel filter took the factory air filter box and put cone shape filter and replaced the fuel pressure regulator off my old engine, checked spark plug wires and the 'plugs' they were black fouled and carboned up so i put NGK platinum's with .031 gap. It seemed to run good for a while " couple hours " and then started to hesitate again and it got worse.
Anyone out there that can help me figure out the problem i would really appreciate it !!
Thanks
