If you press hard down on gas pedal check engine light flashes no power
What is your question?
Miles 220k was driving car went to pass car pressed hard down on gas pedal check engine light flashes no power . Let off gas and power somewhat came back but check engine light was on. checked codes #2 miss fire replace coil. Drove again everything seemed fine 100 miles later it did it again taking off from stop sign this time no power, idled ok dropping into gear engine stalled or would idle but no power. Changed Key switch thought not getting full power to fuel pump but no change... I can start and rev's great then next time at 4k it start bucking like out of fuel and check engine light flashing again.
Spoke to the Honda Dealer he wants $160. to tell me what is the problem i'm sure if I go that route it will be $$$ I get it out of there and hope they fix it right first time.
What makes this problem better or worse?

Hello, flashing check engine lights typically indicate an engine misfire. Due to the high miles of the engine - it's really unclear as to what the root cause is until testing is performed. Yes, spark plugs and coils and fuel injectors are possible causes, but so is the valve train and base engine itself. Has valve adjustments been performed on a timely schedule? The dealership or any repair facility will have to test to find out what is going on.

What location is the coil you replaced? Is it on the front bank (closer to the radiator), or the rear bank (by the firewall), IF it’s a 6 cylinder. Did you change the spark plugs when you changed the coil? That $160.00 the dealer wants, to (theoretically) diagnose the fault(s) correctly, may save you hundreds more in incorrect guesses. IF you choose to respond to either DaveJM or me, I’m sure we can try to walk you through further basic diagnosis, depending on what tools/test equipment you are working with.
