My vehicle has a rough idle. Spark plugs and wires replaced. Check engine light indicates the map sensor problem. Purchased new map sensor and problem persist. Obtained another map sensor and no change in idle condition. I am not sure if the following is related, but the power brakes acts as if they are not power brakes, about half the time. Replaced the master cylinder and the unit behind the master cylinder which controls the vacuum flow. Yet no change in the function of the power brakes. What could possibly be the problem?
have the same problem?
