Idles fine, falls on its face in gear
My 88 suburban has the 350 tbi in it and I've been having issues where I barely have any throttle in gear. It'll idle fine, bogs down occasionally but I tap the gas and it evens back out. When it's in gear no matter if the engine is hot or cold, I have almost no throttle, it'll get enough to taxi it down the driveway but that's it. The driveway being about 70-80 feet. I've already tried a new tps, map sensor, o2 sensor, new fuel pressure regulator, and have gotten nowhere. It's got codes 33 and 34 showing up so I'm wondering if it ain't the actual wires going to it. Any ideas or possible suggestions would be greatly appreciated.
