my engine has been acting up and i have no clue why. it's almost like it occasionally hits fuel cut at WOT high in the rpm range. it feels like taking your foot off the accelerator and slamming it back on there as quick as you can, or for anyone who's ever ridden in a modded turbo car, it feels exactly like hitting fuel cut.


i have noticed that sometimes there is a much less pronounced "miss" that happens in higher rpms as well. that felt more like bad plugs, which wouldn't surprise me since the car just hit 70k miles. think that could be what's causing the "fuel cut" as well? only thing is in most other cars with bad plugs i've noticed that it will sputter anytime the engine is under heavy load, not just at high rpms.


only mod to the car is an aem intake. anyone have any ideas why the car is doing this?


edit: btw i just wanted to add that the car has been fully warmed up prior to this happening.

 

MAP sensor going bad? Try the MAP whack and ECU reset. If that doesn't work, borrow a known good MAP sensor and try that.

 

How many miles do you have on the set of plugs in the car now? Check the plugs after trying the MAP whack or MAP swap.

 

Any resolutions or anything to add to this???

I'm having the same issue. My ride has about 25K miles, but the head was just recently rebuilt about 2K miles ago - possibly something was done wrong or ruined. I've noticed this happening as low as 4K rpm, but only happens under fairly hard acceleration.

Thanks

 

Guys, since my last reply here, Honda has brought out a new TSB on the MAP sensor. This may apply to you:
