As the title states. In neutral or in gear with the clutch pedal down. I can freely rev to redline no problem. But under load as soon as it hits 5k rpms it hits a rpm limiter of some sorts.. its doesnt backfire or anything it sounds like a video game when your game freezes and it's like that loud sound of (Ehhhhhhhhhhhhh)
It doesnt matter if I partial throttle it or at WOT it doesnt go past 5k.
The only codes its throwing is P0352
I've replaced EVERY single sensor on the car with no luck.(o2,map,iac,tps,crank and cam sensors)
Replaced the coil pack,spark plugs and wires with no luck.
Changed my fpr & fuel pump aswell with no luck.
Changed the ecu aswell with again no luck...
When I say no luck I mean a litteral no change what so ever in the way it responds after I changed something.
I am honestly at a complete loss at this point on what it could be. ANY help would be appreciated at this point... I'm open to hear anyone's thoughts or advice to get this thing running right.
