you cannot "clean" the IMAP properly. All you did was clean the temperature part of the sensor that sticks down into the manifold. The most important part of that sensor, pressure sensor part, is buried up in the head of the sensor and cannot be cleaned properly.. with chemicals,. or any other way. ->.. REPLACE IT WITH A NEW ONE!.
