Suggest you add lucas fuel injector cleaner that you just add to gas tank.your plug wires may also need replacement, they break down causing loss of spark, consider what brand you replaced them with last year, we're they cheap off brand? remember you get what you pay for when buying knock off imitation parts.suggest you also replace that old air filter too. hope this helps!!

    2004 chevy trailblazer power loss, high rpms, low ppms

    Check the timing chain. Some times the chain will shift with worn teeth and get out of synch. This will cause the engine to lose power and back fire. Sometimes with a flame through the carb. I did that one once. Easy fix if it is the problem.

    Low gas mileage city and hiway @ 4-5 MPG below MSRP sticker data of 15 and 21MPG on a NEW 2013 Silverado. 2000 miles on odometer and mileage not improving.

    is this calculated mileage or what the estimated mileage is showing on the dash. Have you checked to see what you get on just the freeway?

    What are your driving habits like?

    How is your tire pressure?

    Do you make a lot of short trips?
