Got any codes? Check your crank shaft pos sensor

I already checked crank sensor it's good checked my maf sensor it's good even swapped it with 3 others and still no change .. Sometime the car will run fine I can drive it normal but usually it just keeps giving me that problem

Gonna check the codes today

Oh I missed the "wont pass 2000 rpm" part so that rules out an auto ecu being the case (which is why i was asking if you went from auto to manual). When it hits 2000 rpm, does it bounce off it like its hitting the limiter?

fignewtin88

No doesn't just feels like it cuts out fuel until rpm comes back unber 2k ... Also checked the codes today four codes came up I don't have the exact numbers with me but i remember it was
Iacv
O2 sensors bank one no activity
Map sensor
Nox sensor
I will double check tommrow and I already replaced the iacv and plan on replacing tb and all vaccum lines tommrow see if that helps
