hi everyone I have a 96 Honda Accord 2.7 liter v6 automatic transmission it runs but upon starting it will idle perfectly fine but once it gets to about 2000 to 3000 in normal weather rpms it starts to cut out but once i go past that it levels out and then just dies I've heard vacuum leak I've heard fuel filter I've heard spark I've checked my spark I am getting spark this all started happening after I power washed the motor so if anybody has any ideas please let me know I miss my Honda

 

Check your TPS and MAP sensors, wiring harness and connectors.
Possibly damaged the TPS if it was inundated with water, back probe the sensor with a voltmeter, turn the ignition to II(ON) and watch the voltage change when opening the throttle. It should be a smooth linear voltage change.
