I had to change the cdi because I lost spark. Well after I did that I had to change the coolant temp sensor. Did that, but now still runs bad wont idle or rev and have a continuous blinking red light on the ecu. What does that mean?

It acts like the air intake sensor is bad or a coolant temp sensor but there is no code for the air intake sensor, just blinking red with no pauses?

The blinking light is an error code, or several error codes..

It reads long blinks then short blinks, so something like 1 long blink and 3 short blinks is a error code 13. Post all the error codes you get here, and we'll help you.

I let the brain box reboot after 15 min or so and then I got a long red fallowed by 3 bllinks. I think its a air intake sensor code, but I dunno. ?????

would an air intake make it not rev up? I know it would flood it out but as far as raving up I dunno. It wont go past 3000 rmp. At all. Just seems weird to me. I fixed alot of stuff listening. To all of use in the past on other peoples problems. This is one I just caant figure out. And yes I have a fully charged battery.

Found my can plugged once (solid block of ice) figured it out. Disconnect the springs and let your pipe hang. You'll know immediately if it's the problem

Well I changed the air intake sensor. NO GO!!! im to the point were the problems supersedes my knowledge. I need help. The sled will only idle, it doesn't want to rev at all. It has spurts were it will rev for a split second,and that's it. The ecu has so many continuous blinks I can't even count them! I looked at he fuel, great delivery and pressure. I don't know what the next step would be. Also the fuel injectors are working right. Any help/ideas would be very much appreciated, like I said my knowlage ran out on this thing. Batterys fully charged also. I dunno.......
