Hi. i got a 97 civic w/ a Itr on Hondata s200. Ive been daily driving it for 2 years never a problem, but sincne yesterday it wont go over 4k rpms. It just sputters like im hitting the rev limiter or 2 step. Also the blue hondata interface box is slowly blinking red, for the past two years while it run fine it was solid red. Help please.
Thanks.

 

look into why the box is blinking with hondata,
is it trying to show a code,
the one that has you in limp mode?????????

 

The interface cable has probably been damaged. Check the 4 wires for continuity. You can purchase a new interface cable through any Hondata dealer.

 

My h22 did that when my dizzy was going out.
