My engine light is always on and off every 300 or so miles it goes off then 30 miles later it comes on. I didnt change the Engine ECU but its so annoying the rpms go crazy up and down all the time. Is it all because of the ECU?

 

Have you checked for any stored codes?

 

I been driving like this for over a year now, everytime I check codes it blinks 05-05

 

Did you leave the auto ECU in there?

 

doenst he auto ECU usually blip the throttle after every shift?

 

The shop that did it for me left the auto ecu..

 

what do you mean?

The only problem I have is the rpms going crazy on me on every stop light takes few seconds for them to drop down to idle level.

 

I'm not quite sure, but I think mine does that.

Switching to a 5spd ecu would probably get rid of the light.

 

Do you know how much they cost?

 

I really wouldn't know. probably alot new, but check out www.car-part.com and the 4th gen classifieds.
