Car run rough and check engine light is on I got the code for knock sensor 1 &2 and map/baro switch solenoid then I erased the code with scanner but only one code remaninig which is map/baro switch solenoid p1105 pending. As soon as start the car the check engine light will come up everytime I erased it come right back up. Sometimes when I got my foot on the gas pedal it would'nt response like hesitation someone told me that is no more than vacuum problem. Please I just need you guys opinion what I can do to solve this problem thanks in advance

You have to check that circuit out to see why, or it's a bad sensor
