Ok, Here is my story.
About a year ago I drove up from Vancouver to Kamloops and drove around for a couple days hunting and fishing etc.... and on the way back up the Highway (Coke) The engine started hesitating under full throttle. Needless to say I had to nurse it back to home to figure out what was going on. After a bit of research I learned that my exhause was plugged. I got my cat taken off at a muffler shop and a straight pipe put in. This fixed it right up and it sounded pretty good too. Then after another trip up Kamloops the same thing.... I thought it might have been air filter but checked it and it was fine. I figured that it was the exhaust and also got the plenum gasket done at the same time. (ordered the one through hughes engines) I thought that would be the end of my worries. Now once again the same hesitation is coming and power is down to about 70%. Someone Please help me? Had to unscrew both O2 Sensors to get some flow there, and that helped. Any thoughts would be apreciated.
