Hi everyone,
I've been trying to fix an issue where my 2.3l FI engine bucks when under load. You can drive it around at 50-70% throttle alright, but if you apply any more throttle the engine bogs and bucks violently. So far I've done the obvious things, new plugs, wires, coil, Fuel filter has flow, and the vacuum is good with no leaks. The cap and rotor were done 16k ago. I'm kinda scratching my head here. It will drive better for the first 30 minutes then the throttle issue gets much worst, especially on any sort of incline, to the point where it will struggle to maintain safe highway speeds. I'm fairly certain both pumps are operating correctly. It also idles quite rough. Any ideas? I'm worried it might be an actual lower end or engine issue or bad rings since the problem seems to worst as you drive it. Thanks!
Andrew
