did a trans swap lately and now at idle it stays around 11-1200 rpm
while driving it just stops at like 1900-2200rpm cant figure it out changed maf 3 times

 

Trans swap? Auto to manual?

 

Manual I blew up my last 5 speed a few mOnths ago

 

Is the throttle cable getting stuck some how??

 

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?

 

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

 

Hose?>O2>MAP>MAF>WIRE>ECU

In that order..

 

After all this work I found the problem bad tps car runs fine now
