First thing you should do is to check to see if any DTC codes have been set by the PCM. Either buy a code reader or go to a shop or parts store that will read the codes for you for free and post them here. Without those codes, we would be guessing. Is your check engine light one or are you getting any messages?

Please don't type in CAPS it is like YELLING

It sounds like the guy had an OBD code and was guessing from that. Get the codes and post them here and people who have fixed similar problems can help you out.
