Suzuki Baleno or Steem 16v Motor 1,600cc.

Hello everyone, I have a problem with my car a Baleno or Steem Suzuki in other countries, it turns out that I change distribution strap, after changing the belt I turned on and worked super accelerated, the acceleration deconed the battery and I hope as 1 hour later connect battery and everything now now the car gets out of control in idle and consumes an enormity between 8 and 12 km/lt, approx. Before ease it reached 15 km/lt, all of the above in the city, someone knows if apart from the regulation of air passage this car brings benzine passage. And another thing this car brings two brands on the camshaft pulley which is the correct synchronization brand with respect to the crankshaft.
