4 - 5k = wtf? coil packs?

[Jcs]

Had the clio in the garage last week getting my exhaust sorted. Came out and seems the from 4-5k its reluctant to rev.

Wondering if this is to do with the coil packs or something else

vid to show what i mean

 

[biojo]

how long was it since u started car up?

 

[CuppyDean]

Looks very hesitant to rev, sounds like its misfiring to badly but that maybe just the sound quality

just noticed that on the cold rev limiter lol. was a few minutes in just to video it there.

But after a good gentle warm up it does it to. But its every other day atm. Not all the time

fillmed with an iphone with window down so not good sound quality sorry

Your engine management light is on get the fault codes read.

Were you holding it at 4krpm to over-emphasise the drama or does it genuinely hit that rpm brick wall?

+1 - Get it to the shop!

The engine management light is coming on as it is misfiring

Fuel is entering a cylinder and not firing

The post cat lambda will pick up this and switch on the engine management light

Could be a dodgy plug possibly

Nope that was foot down to the floor and it was just no power.

After having an exhaust gasket kit fitted to the decat and the exhaust being welded due to serious blowing near the join the garage started the car without the lambda plugged in, which brought the engine management light on. Flagged up o2 sensor which I assumed (which i should obviously never do) was the reason engine management light was on.

Up at JMS on friday so will ask tom what he thinks

it is due a service in 600 miles so plugs will be changed there

Ps thanks to all those that have responded.

If you dont resolve it before 600 miles you could end up knackering the cat too

Just about to order some NGK plugs with service kit from NW performance.

Running a decat instead of cat.

Not if it's not on the car he won't.
