I was tunning a B16A with Brain Crower, CPR pistons, stock injectors, everything was fine but after awhile engine won't go past 2k rpm. I change ECU with stock one and keep doing it.
I will appreciate any help.

thanks

 

Check engine light on?

 

I was using hondata S300, an IAC error code came out. it was intermittent.

 

On a stock car an iacv code will throw the car into limp mode = no 3000+ rpms

 

yes, engine light came on.

 

thanks, saturday I will remove IAC and replace it. I also read by cleaning it will help.

let you know how it went

 

today I worked on the car and look into the IAC and found TPS Sensor unplug.
thanks for your inputs.

 

sounds good...it's weird that the iacv code came up ... however on some cars you can accidentally swap the iacv and tps sensor connectors...hoping that didn't happen to you.
