Question about Hyundai Excel
What you are guessing (timing chain) is on right track.
In this case we have to look at the Variable Valve Timing Control system.
Valve Timing Control
1) The PGM-FI system monitors the Valve Timing Electronically Controlled (VTEC) System. By monitoring various engine sensors the ECM can determine when to activate the hydraulic components of the VTEC rocker assembly to engage VTEC and similarly can verify this function by monitoring the VTEC pressure switch.
2) The VTEC usually kicks in at about 3,000 to 3,500 rpm so if the PCM sees it's not working, it limits engine rpm. A code should set in the PCM but it might not be a 'hard' enough failure to set a code.
3) You have to be very careful when checking this system since actuating the VTEC system at the wrong time could cause severe engine damage. I would recommend taking it to a Dealer and letting them drive it with their scan tool connected so they can monitor the VTEC operation in real time and see exactly what it is exactly doing, or not doing.
