Quickstory, turning on to a road here pathfinder cuts me off from parking lot I switch lanes floor it and car goes nowhere. the pathfinder literally out accelareted me. Mods in sig it's been a bit of a dog below 2000 rpms lately but running good over that, twice now though I've floored it and it really fills like the car is just stops, winds up then takes it's time to go. what the hell!!

 

Any rough idle> OPTI. I really hate to tell you the opti is bad... Check all your plug wires too. Mine did something similar to that and it had a couple burt wires.

Does it do it neutral or just in gear?

Make sure that all your sensors are fully plugged in. Check the one on the intake elbow especially.

 

I checked the wires none are noticeably burned, idle is okay, any way to check thre opti?

 

If you're running a cat, it might be clogged.

 

No cat, changed fuel filter last weekend too.
