As mentioned 2000 Camry 2.2l. Idles fine and runs strong at full power. Stumbles/surges while maintaining steady cruise speed or under normal acceleration from dead stop. Issue starts after car warms up. Cleaned fuel injectors, Tb, and IAC with no change. New air cleaner, spark plug wires are good and not shorting out anywhere. Plugs look fine. Car dies if I unplug MAP so it seems to be working fine. Any help appreciated.
