A guy I work with wants me to replace the timing belt on his 2003 Civic EX.
1.7L MFI VTEC.
112K miles.
The instructions I got tell me to disconnect the battery - no problem. But then it says I need to "reprogram the ECM/PCM engine idle characteristics". Is this a program that needs to be downloaded back into the ECM?
Is this something best left to a dealer?
Any other things to watch for while doing the work?
He would like all the belts changed, along with the water pump and the fuel filter.
TIA for your help.
