    99 ACCORD, REV limiter crazy? HELP ??

    SUP yea'll
    i have a problem i just bought a 99 accord ex, with the VTEC motor, when i'm idling on Park or NEutral it backs off( rev limits) at 5000 rpm. but when i'm driving it REV LIMITS at 4000 rpm. SO when i want to pass some one and i mash it a lil it starts to rev and wouldnt go NO WHERE it almost killed me yesterday. if yea'll no i would really appericate it.

    thanx

    1. I have no idea why you'd want to rev in park like that.
    2. what transmission? AT? MT?

    The idle rev limiter is there so you don't screw up your engine more than you already are from revving it out of gear. Since there's very little resistance on the crank (read: no gear), the engine spins almost effortlessly and it's very bad for it. Maybe your car is trying to kill you for beating the crap out of it like that.

    thank god for having that limiter if not ur car will blow up.
    is a fuel cutoff so u wont kill ur car, and why would u want to go above 5rpm while in park.

    oh wait it wont go over 4-5rpm while driving it mmm there is something wrong then. how miles the car have? maybe when they did the timing they did it wrong. u should be able to red line it while driving like around 80mph for our slow auto.

    Well I'm telling you that you are dogging it by revving it out of gear. It's probably one of the worst things you can do to an engine besides running it without oil or taking the air filter off. I rip on my 192,000 mile old car daily and take it to redline maybe 5-10 times a week but the engine still purrs (aside from valvetrain ticking) like when it was new.

    You need to explain the circumstances more, what speeds, how are you driving it, what throttle, exactly what happens, etc.

    and when i'm driving it normal it shifts around 2700-3000 rpm smoothly. when when i want to down shift or pass some one it does the rev thing.

    Maybe your EGR valve is extremely clogged? Does it throw any check engine lights?

    VTEC doesn't engage when it's low on oil.

    I know that VTEC engagement on the i4 is something like 4500 or 4800.

    But the engine would still rev past that point.

    Yeah, I think the problem is that your oil pressure is low. If so, VTEC will not engage and you won't be able to rev past that point

    Not really, on the I4 if VTEC engages around 4900RPM's that's when it switches to the higher lobe which demands more oil pressure. But if your car is low on oil, it won't switch over and VTEC will not engage. Thus, the reason of not revving past 4900RPMs in park or a drive gear

    ...the engine will stay on the low cam if the oil pressure is low. The neutral rev limiter has nothing to do with oil pressure, I already explained why that's there. That's totally seperate, enough of that.

    Haven't you ever driven your car when it's cold and needed to swing the tach up to get out of a tricky situation? The engine just doesn't hit VTEC engagement point and stop, it just stays on the low cam and it feels gutless.

    Well, according to my experience and not something I've read, my car (along with others I know) will not rev past 4900RPM's with a low oil pressure. It's happened to me twice since I've had to car.
    I would have thought there was a problem with my car, but I doubt it if other people with F23A and J30A1 motors have experienced the same problem

    Oh. I've never had low oil pressure, so maybe I'll try draining some out this weekend and testing it My point is that just because VTEC isn't engaging doesn't mean the engine won't rev past that point, at least on the J30A1. I guess if the oil pressure was low then maybe the ECU wouldn't allow it. I'd like to hear if moo found checked his oil yet??

    Check your oil, that's the only thing that would cause abnormal pressure aside from a bad oil pump I think. And you'd know if you had a bad oil pump. If your oil pressure was really low though your light would come on...

    So the car still will not rev past a certain point in the rev range when it's warmed up? Does it just STOP like you've hit the fuel cut off? Maybe the ECU is bad or something, that's weird.

    Exactly. It's like hitting the rev limiter but at 4900RPM's
    The first time it happened to me, I was scared. I was racing a 99 base TL and going through a nice left hand turn I was pulling on him, but suddenly my tach started bouncing at 48-4900RPM's and I was like WTF. So I posted my experience and did a search and come to find out, a couple of other people had the same problem and said it was due to low oil. I'll admit, I was overdue for an oil change so when I got it changed I went back to the turn and hit it harder than before and kepy accelerating and the car pulled through there nice and hard.
    Here's a few other links of guys who had the same experience
    Click 1
    Click 2
    Click 3
    Click 4
    And that's only on this board. Almost every board I'm on, someone has this problem with their Accord

    Moo, check your oil yet? Was it low?

    Good info blackknight, I had assumed that the first thing he would have done after we responded would have been to check the oil.

    i just changed my oil, still same problem, and my oil was good before i changed it anyways.

    i got sick and took it to a shop to diagnose it(on the machine) it said Vavle timing oil preasure sensor, so i went and bought it from HONDA for $114. and still did the same thing, so today after work i'm going to the store and checking it again(after i kick that dudes ass for the wrong thing) not really .


    thanxs yea'll, adn keep me posted

    If it was valve timing oil pressure sensor all that would happen is that VTEC wouldn't activate IMO. You might want to take it to Honda, this is a really weird problem that I'm boggled on. I'm dying to learn what is causing this.

    hey 98coupev6, if i have a CEL(vtec malfunction, not sure if its 1259, unless theres only 1 vtec code), whenever i accelerate hard, the car feels bog downed, and the theres a point where the tach jumps up and down (im not accelerating anymore also), i assume that is the rev limiter, is that bad for my car? im tryin to trouble shoot if its a bad vtec solenoid or a bad vtec pressure switch.

    VTEC malfunction? That's very rare. Since VTEC is oil pressure actuatued, there's a solenoid (as you said) with an oil filter (a screen I think) near it. I've heard of that screen getting clogged from using dirty oil, so check there. If that's fine, I guess troubleshoot the code.

    That's a possibility also.
    I'd also have then check the VTEC solenoid also.
    But regardless, if it's not a low oil pressure problem, you should have some type of code instead of someone guessing the problem/solution

    im not guessing, i checked the CEL code, cuz I had a CEL. btw, i did what u suggested 98coupev6 with the cleaning the shield. the code im getting is 1259, unless like otherwise stated theres more then 1 CEL for bad vtec. i took the car to honda, they said get an oil change, did that. then they suggested an oil flush, i said, wouldnt the oil change be the same as an oil flush if that was the solution (being low oil or flushing out contaminents), the technician said i am probably right, so they did not do that. NEXT, they did actually what u suggested 98CoupeV6, the vtec solenoid shield gets clogged, so they cleaned the shield, and NOW i STILL have the code. so its either 1) bad solenoid 2) bad vtec pressure switch ... your thoughts gentlemen

    I'd lean toward a bad solenoid. But I'm not sure.
