View Full Version : CR-V Hesitation...Anyone Figure it out??

I was just checking back in after discussing with my dad about the hesitation problem. We both have 04 CR-V's and have the same acceleration hesitation. It seems to accelerate in stages. I had the throttlebody replaced to see if that would fix it, but it did not. Fortunately I bought the Honda Blue Care Warranty just to cover the AC problem when and if it happens. $995 for the warranty, $1500 -$2k for the AC repair. So I was just checking in to see if anyone had figured out the hesitation problem most seem to have...

I think it's a Honda thing as my crv does this as well. It does it worse at higher RPM's.

I wonder if a SEARCH would show that people who tried injector cleaner saw any improvement? Next best guess would be low coolant (air in system). The computer really doesn't know what to do with that one. . . .

:idea:

I have used Techron fuel injector cleaner in mine every 4k miles. However my CR-V has done this high rpm hesitation thing since day 1. I drove an 07 Accord that did the samething. That is why I think it is the nature of this engine.

Techron is $5 a bottle and never bad to take a shot.

Bsexton (can we call you something besides that?) have you tried watching (as well as anyone can while accelerating) the different "gauges" on the scangauge to see what changes are taking place at the time?

I'm in QA, can anyone tell I'm constantly in debug mode? :D

What hesitation problem? We hit the throttle pedal and it moves. Nail the pedal and it moves even quicker, straight to redline, shifts all by itself and revs to redline again, when it shifts all by itself, again.... :)

If you hate my last name that much, you may call me Barry..LOL. I have watched all of the specs on the guage such as closed/open loop of the O2 sensor, map, IAT, and such. I don't really see anything abnormal. It only happens with mine under very hard acceleration (like merging onto the freeway from an on ramp) and it just feels as if the acceleration is in slight spurts and not real smooth. Honda dealer says "its normal", I started a thread a while back about and other's have noticed, and the Accord I drove did it. So I am writing it off as a Honda thing.

hmmm... have you reset the auto tranny/ECU by pulling the battery cables? That may be worth a try. They "learn" and try to adapt to your driving style. I notice that if I drive the wife's 04 after she has been the only driver for a few weeks that it shifts differently. That is, until I make the sucker learn higher rpm shifts should be in order... :)

I have had my battery unhooked several times for my DRL install and radio install, but I don't see any difference in the shifting or acceleration. I know the learn thing is a fact though because my Suzuki Esteem idles really, really low and shifts like crap after the batt has been unhooked. After a little bit of driving, it "fixes" itself.

You know, I'm wondering if the ELD system has any play into this. It's another one of those "black box"es inside of the CR-V that has some secret little magic that goes on with it.

A/C is ususally the theif that steals get-up-and-go . . . the alternator could do that at certain points if it's running when it doesn't have to.

That defeats the purpose of the ELD, I know, but it could account for different power points . . . just another one of "Ernie's Theories" :D

And yes, that's better Barry. B.Sexton feels very . . . high school gym/boot camp :D

That's it. That is the word I was looking for. "Power Points" (no not Microsoft) during heavy acceleration. Now I don't know if your idea about the "black box" is so, but one may never know. Honda may be Big Brother after all.

That is SOOOO funny because my high school PE teacher used to say "B.Sexton, give me 20 laps around the gym" :) Although, I must say that is a much better name then the one I got at college. My username and student ID was "BARSEX"...hummmmm.

:shock: :shock: :shock:

Anyway, the "power points", I think of it this way:

0 - 2100 PRM = Emissions :?
2100 - 4500 = Efficiency 8)
4500 - Redline = Power :mrgreen: :mrgreen: :mrgreen:

I can feel a surge at each of those areas.

The surge I feel is typically below 4500rpm. Once vtec kicks in it seems to pull smooth. Sounds like no one has figured this one out yet..no biggie, just not as smooth as what I would like. Not giving the CR-V up just for that! We love it!!

The official VTEC "kick in" point is at 2250, as per Honda.

Yes it is because I tried adding a "VTEC light" and it was on most of the time while driving.

Did it ever go off above 4500?

I have no idea because I never tried it that high.

WHAT?

You have never gone past 4500 rpm's? You have a HONDA that was designed to produce its' power at well over that! Take the damn thing to redline. That is why you are having "surges". You keep letting off of the gas pedal.

You have never even reached peak power and barely got to peak torque! Peak HP is at around 5800 rpm's and does not start to drop off until near redline!

WOOO..Let me rephrase. I never got it past 4500 rpm's WHILE I had the VTEC light connect. Trust me, it has its share of high Rpm's on a regular basis.

Of course, they then complain about the gas mileage they are getting. Because, of course, the engine was not designed to give great mileage at such low rpm's.... They just don't get it.

It's a 4cyl HONDA. I don't know how they would get the thing up a hill staying at 2500 rpm's. When I merge onto the freeway, I always have to accelerate HARD just to be able to get in the flow of traffic.

Odd.

I end up braking hard and downshifting to get in the "flow of traffic" :mrgreen:

Not here. Trying to get on I-81 in the area I have to merge, its like trying to merge onto a speedway during a Nascar race.
