okay i was driving home one night and the car just started bogging. pulled over and coulnt find the problem cuz it was dark a$$ hell. came home and parked it. next morning when i started my car the valves started knocking and notice fuel leaking out from one of fuel lines replaced it and still have the same problem, car boggs when under throttle a lot of back firing and my boost guage just jumps up and down as if it were boost sipkes. i then did boost leak down test and there wasnt any leaks i checked timing, was way off and set it at 15 btdc. it running better now but i am stumped!!! any ideas what could be wrong with my car.
