I had the same issue and tried all the above. my kernel_task would sometimes go up to 3000 (how?? i don't know) - ran hardware test: Error code 4SNS/1/C0000008:TN1D--124 Managed to resolve it by changing the trackpad cable. looks like the tea spilled dried on the ribbon making it go haywire. simple solution really but Apple asked me to 400 pounds to fix it...what a sham.
