changed the water pump (which was a pain) Instructions said to take NEG side off of Battery. When job was complete, there was a rough idle with code po300. I took off Throttle body and cleaned it with sensor safe throttle body cleaner, re-installed and same rough idle. Reset code no change. Started car and let idle and drove around block to get normal engine temp and check for leaks. Water pump job OK. Cannot get idle back to normal. I read the computer has to relearn the clean throttle body position. I am wondering if when I put the new water pump on as I tighten the pulley, it rotated the crank. Would this mess with the variable timing? I assume the computer would know. No other codes. HELP!!
