engine missing and bad hesitation problem
my 93 blazer has been running horribly for a little while now and i cant seem ti figure it out..it idles alright but when you give it gas it misses real bad and boggs. just dosnt want to go anywhere or do anything. the first thing i was told it was, was a leaking spider and it was so i replaces it and no more leaks, problem was no longer as bad but still there. so i replaces plugs, wires, cap, and rotor, with not much of a change. after that on a test drive the SES light came on and i pulled over and checked and i got a knock sensor code and a MAF\MAP sensor code. i replaces both and again not much of a change but no more SES light. i checked the fuel pressure and that is perfect, checked the TPS, checked and cleaned the IAC valve and air filter. all were good no SES lights and still getting the hesitation. almost like spark is dieing when more and more when the throttle is depressed..any ideas because im about out...
