Wouldnt you know it. A brand new exhaust gaskit GONE.. I had a exhaust leak.. A bad one.. right under my T-stat housing. It was leaking a small amount on top of my exhaust mani and blew out the gasket. Well Tonight I replaced the T-stat housing gasket , the Exhaust gasket , put a brand new FPR in( THANKS WARREN-CUSTOM LOCK-) and replaced the AFM And a new 02 senser. I replaced the AFM , FPR and 02 senser cause I am getting something weird happening while driving. Under acceleration it drives perfect. but during cruising or just staying at a steady rate of speed it will be fine and then start missing and bucking. If I blip the throttle like 2 times it straightens right out and drives fine for a little while and then does the bucking again. I am at a loss to what it is. Anyone ever had this happen to you?? Thanks for any advice I may get..
