Little blue
Newbie
I’m new to this form but am in need of help and this is going to be long so please bear with me. I got the truck in may of 21 and at the time was not starting well or at all and was burning substantial amounts of coolant so I went through and replaced the head gaskets, intake gaskets, throttle body gaskets, alternator, all the pulleys and belt and I also replaced the plugs, wires, cap, rotor, coil, and ignition control module all of which are ac delco parts.The truck was doing great until about January maybe a little before that. It was throwing codes left and right, barely running and had zero power. So I went through and replaced the o2, tps, both temp sensors, map, egr vac hoses, grounds, pcv valve, and the ignition switch. It’s still not running right but all the ses lights have went away. If i floor it from a stop it bogs to almost 40-45 then feels almost like turbo lag because at or around 45 it kicks and takes off. Anything below that it’s a complete dog. I had an aluminum 6x10 with a small zero turn on it going up a small hill and had to have it pinned to stay at 30 and burned a 1/4 tank of gas in 50 miles. And my standard gas mileage went from 14 to almost 10. The oil also smells burnt and like gas. Also when I have people behind me they say it smells like straight gas. Also sometimes when I pull to a stoplight it will try to die then smooth back out then rev way up for just a second and try to send me into traffic. Please tell me what you think this could be anything helps. Thanks
