If you have brakes that are adjusted too tight, you will know it in 1 or 2
miles. Lots of excessive heat at the wheels just from driving.If it is real
bad, you will get smoke, and soon.It only takes a few clicks of the
adjuster to get brakes too tight.I adjusted mine to where it takes one or
two clicks more, for brake drag Just  a few. Is it your e-brake that was
just adjusted? The proceedure is to get your brakes properly adjusted
first.After this, pull up on the parking brake lever and check the total
notches it takes till on full. Release the handle and adjust th 10mm nut
where the parking brake cables come together.Tighten it to get a tighter
handle.

I say check your timing and throttle valve adjustment ,and air screw for
idle air bypass.Good luck
