Can't go past 2k RPM, what gives?
 

-

swapped MAF and the crank angle sensor. I guess all thats left is the throttle body sensor? Would anyone happen to have a spare TB or TPS?

sounds like your in failsafe. Check the computer for codes before you swap more parts.

Sounds like your cars in Limp mode. I have an 05 and that happen to me once. I unhooked the battery over night and it never did it again. Hope this helps

Checked the codes with the scanner and P1124 - Throttle Control Motor Relay shows to be detected.

Would you think a new relay would fix it or would the whole throttle assembly/TPS be the cause of the problem too?

The weird thing is, once i resetted the ecu, the car didnt pick up the code until 30-40minutes later. When it didn't pick up the code the "SLIP" VDC off and ABS light were on the gauge cluster constantly. Once those lights turned off the OBDII scanner picked up the code.

bring it to the dealer if it's still under warranty

bring it back from the dead. Did you just replace the TPS, or the entire throttle body?

bro i have same problem i replace TB. but no luck.
can you tell me where is Throttle Body motor relay located????
