Rev limiter at 4k?

22nd February 2010, 07:49

Got a problem with my 51 Plate VTR.

Was driving it on friday and everything seemed fine, was on my way to work today and suddenly I cant rev past 4k!

I mean it revs fine doesnt splutter in neutral but seems slightly sluggish in gear and then 4k revs and no more.

Theres no EML on.

Ive had misfiring problems before but I managed to fix it with new plugs and crank sensor. When I parked up I noticed steam coming from the bay but it just turned out to be water from the road cooling off the radiator. Its raining pretty heavily and i went through a few deep puddles any chance waters got in somewhere? I could try changing the coil pack but I hate spending money on things i dont need lol

Otherwise any other ideas?

mate prefect... put a 16v in there lol get it on a dignositcs sure the garage will tell you the problem

22nd February 2010, 11:41

Im reluctent to take it to a garage I dont like other people touch my car

I drather diagnose and fix myself.

Anyone else shed some light>?

Does sound like a coilpack problem, but suerly the EM Light would be on?

One of your spark plugs not sparking?

Faulty ECU?

Could be loads of things. You got a friend nearby with the same car you can swaps bits for to try and find out which part is at fault?

22nd February 2010, 12:08

Dont the ecu's limit revs when an issue is detected? As above fault codes would be best bet.

Cheers dudes

I havent been able to have a good look yet as it happened just as I got to work. but ill definantly look into the spark and coil pack.

I'd say crank position sensor at a guess.

Mine was wired up a bit dodgy and I had a 6k rev limit - when i cleaned it and changed the distance between flywheel and the cps the rev limit moved.

I've re-wired mine now and it's spot on!

Water could have buggered it or moved it ?

22nd February 2010, 14:38

I would have said Crank position too.

There isnt a ECU light on on the dash as youve said, but when it hits this rev limit does the ECU light come on for a split second as it hits the limit? Thats what it did on my mates car when he had this problem.

Have you tried to disconnectin of the battery to reset the ECU stuff?
Have you tried getting it plugged in on a diognostics?

Also does it rev to normal limit in neutral?

22nd February 2010, 14:53

Idles fine and I have recently just changed the crank sensor and it has worked perfectly for months!

I finish work soon so I will see what its like on the way home. Thanks for the replies all!

22nd February 2010, 16:02

Right have done the drive home.

Definantly mis-firing drives fine in low revs all gears, mis-fires in high revs under sudden accleration. Ive had this problem before so I will first change the only thing I didnt change last time. And that is the coil pack but ill wack some new sparks in too jsut for good measure.

Thanks for you input everyone.

same mines a 1.1 and limits at 3k pm me too pleasee lol

this happened to me, try doing a soft reset on the ECU (disconnect the battery for 10 mins) give that a go, sometimes the car can go into limp mode without setting the engine management light, so far i have got it down to being the coil pack, gonna try it this weekend,

hope this works mate, i know what its like GUTTING!!

Cant hurt I suppose ill try that! Yeh ive got no performance atall

I would have thought if it waqs a sparking problem then it would surely be running on 3 cylinders, not stopping the revs

Forgot to add the limiter is back to normal now but its definantly sluggish and misfiring. Would the EML come on if it was only running 3 cylinders?

It sounds like exactly what was happening on our C4. Turned out to be the coilpack.

Really slow off the line, stuttering through the revs and topping out well before the limiter. It was essentially running on 3 cylinders and pumping a load of unburnt fuel through the system.

Our EML didn't come on but each time it got hot there was a warning about the cat that flashed up on the dash

That sounds about right tbh! Getting more pops and backfiring more too so I guesse thats the unburnt fuel. Definantly replacing the coil pack now

Thanks again!

Ive got the same problem with my mk1 vtr, it wont rev past 4k ive changed the fuel filter and it seemed ok for a couple of days and then the problem came back, i have no idea what is wrong with it please help!!

14th November 2013, 18:01

rev limiter cutting in at 4k is limp mode. a sensor of some sort will be down.

15th November 2013, 12:12

Thanks Il have a look at that, any ideas on what sensor could be down?

My other half's 3 plug VTS had this problem for a while, along with refusing to idle. Tried pretty much everything we could think of to sort it, but the issues went away after a few weeks of using the car on a daily basis. Almost like the ECU re-calibrated itself?

My advice is get yourself an OBD2 code reader and check for any fault codes. Just because the EML isn't on, don't assume there's no fault codes logged. With any luck, the fault code(s) will point you in the direction of a dead/ dying sensor.

If there's no fault codes, then I'd recommend tracking down someone with the proper Peugeot/ Citroen Lexia diagnostic kit. Not something I'd usually recommend, but you could easily spend hundreds changing sensors when it may be fixed with a simple re-calibration with the Lexia.

seems like going in a puddle might hve splashed water to ge to a sparc plug, it can go takes time for it to dry, had this problem before in my vts
