Engine Malfunction

Re: Engine Malfunction
ОK.
Here is my impression after new transmission been installed and driven for around 2000 miles.
The car got much stronger response to the gas on the highway.
The car kept vibration issues while light acceleration at low speed/rpm.
Assisting function works inconsistent (90% of the time rather slowing down acceleration in the first moment after stepping on the gas).
Assisting function does not work on steep hills even when battery indicator is full.
The car slows down significantly when rolling down on steep hill (around 40-50 mph) in charging mode and with released gas pedal (does not slow down when charging is not engaged).
In order to disengage charging mode while going downhill do the next:
1) Release the gas pedal
2) Select “Neutral”
3) Wait 1-2 sec.
4) Select “Drive”
5) While doing all that do not touch the gas pedal
In order to reengage charging mode while going downhill do the next:
1) Slightly step on the gas pedal to make RPMs jump above 1500-1800
2) Release the gas pedal
This procedure works on my car at least. Do it when there is NO car in front of you!
To me all these symptoms but one are pointing on bad synchronization between electrical motor and ICE.
Vibration issues may be originating from active engine mounts running out sync with ICE.
FE does not impess me at all (whatever I do it is not more then 32.5 MPG average now).
What do you think of this?

Take it right back to the dealer ASAP
Ask for a Honda Regional Service Rep. to discuss HAH.

Hello tigerhonaker,
Which of those symptoms do you experience with your car if any?
Do you see green bars of assist while climbing up hill?

Re: Engine Malfunction
My wife actually drives the HAH now as I stepped away from the Hybrids
and went back to the High Performance cars.
I don't think you get the Green Bars when you are going up a Grade.
Because as I recall you are dropping off the 3-Cyclinder Mode and
switching back to the 6 cyclinder Mode. So there is NO Green Bars while
going up Grades.
More on Level Ground and also when the ECO light is lit up showing that
you are now only using 3-cyclinders.
In town Mileage is NOT very Good at all.
And that depends on how one takes off from Stops.
Hwy. at 70MPG seems to me was 34 MPG.
Hope this answers your question.
So I still have the HAH but don't drive it like I use to.
I mainly drive the 2008 Bullitt Mustang these days.

Re: Engine Malfunction
Sorry tigerhonaker my bad.
Of course I meant BLUE bars of assist not GREEN. Did you see blue bars while going up hill and tried to keep the speed constant? Do you fill a torque from the electrical motor if blue bars appear? I fill almost no additional torque even when all blue bars are shown. I remember a good kick of torque coming with assist a while back when my car was new.

You know I never paid any real attention to that.
Hard to believe I know but True.
My HAH always ran and does really Strong so I just never paid much
attention the the Assist from the IMA.
I do know from a Stand-Still and you floor it Immediately it would brake
the tires loose.
Very Strong from a stand still if you did not let it get into 2nd gear to
early from take off.
So, I can tell you also that when going up Grades (Medium) where the
car would have the Eco Light ON. You could see the IMA add more and
more Blue Bars to try to keep it from switching back to engaging the
6-cylinders. Some times it would work if the Grade was Gradual and the
Assist from IMA could keep the speed constant with the Cruise Control
Set. If the Grade was a little to steep then the Assist would 1st Engage
then the ECO Light would go out and you would be running all 6-cylinders
until you got back on Level Ground or almost Level.
To answer your question though.
There was NOT some big change in Conceived Power Increase just because
the IMA would kick in as I recall.
It just would attempt to keep the speed constant with the Cruise Set.
BTW, the HAH still only has like 11K miles on it today.
The wife works here at home for her company.
So the HAH is not driven very much.

Re: Engine Malfunction
My car broke the tires loose from a Stand-Still when it was new. Now it has good but not rapid acceleration until you rich 50 MPH then it shoots forward (feels like old VTEC). I think dealer set some limit for assist at low speeds. It is good if will extend a life of the transmission.

Re: Engine Malfunction
OK. The vibration issues while light acceleration at low speed/rpm have been resolved by switching to branded gas (Shell, Exxon). I followed dealer's mechanic advice. I wonder what is the ignition advance angle setting now? I guess the gas I used to put in was a crappy one.
But I still have problems with motor assist.
Sometimes it is fine but sometimes not.
Sometimes I fill the car constantly trying to turn the tires faster then suppose to while I cruise. Sometimes it is opposite (the car tries to slow down on its own). It causes the vibration from them like they are not balanced. If I switch to N the vibration goes away.
