My Suburban acts like it's starving for gas when trying to achieve freeway speeds or when at 1/2 to full throttle going up hills. I'll get hesitation, sputter, gasps or coughs (almost backfire-ish), and even clunks. Just replaced fuel filter and it helped with starting, idle (still slightly rough, but doesn't die now when cold) and power, but now have this issue. Anyone have this problem before? Recently replaced coolant temp sensor and knock sensor to fix non-running problems. No error codes now after reset.
