I have a 1996 accord ex (2.2L VTEC) recently the check the engine light came on, and the error code read 74. I have taken the car to two local shops, first one said it's not s serious problem and does not need fixing. The second shop said they need time to figure things out. Could someone please tell me what it means and what i should do, many thanks. By the way the car drives fine and passed emissions test and inspection test. I could not detect anything unusual about the engine even during high speeds.
