I just wanna get some helpful advice not gonna make a long list but just a few issues I'm concerned with !!! 1) changed timing belt ignition rattles when under load!! 2) changed speed input sensor and transmission fluid Mitsubishi SP111 transmssion was going fine until i noticed a lag in the gears before changing !! 3) A/C vaccum and the idle step up sensor seems to be fluctuating in idle speeds from time to time not remaining constant !!! Any advice would be greatly appreciated on how I can remedy these drawbacks!!!
