when it gets to 3k rpm it really gets to shaking and the bogs down and dies. We've replaced the battery, the accelerator sensor, the coil packs, and the fuel filter. We can't seem to figure out what it is. It jerks pretty bad and the exhaust smells 'richer' than I'm used to. After it hits 3k it coughs and shakes.please help I haven't been able to drive it.
What makes this problem better or worse?
It's ok as long as you're fine driving 20mph
