My husband was driving earlier today and all at once the check engine light came on and he experienced a reduction in speed (not able to go above 45). We recently had Jiffy Lube change the oil and check/fill all other fluids. It has had regular oil changes. My husband is convinced it is the transmission but the fluid is fine and does not smell burnt. Is there anything else this might be? It seems really sudden to me and Jiffy Lube mentioned nothing that the car needed replaced (timing belt, etc). The coolant was low when my husband pulled to the side of the road, but the car gave no indication of overheating. Thoughts?
