Need your thoughts... Clio 197 down on power

[Appsy14]

I have a 2006 Clio 197, completely standard.

So I was driving home from work the other day and noticed when I put my foot down not a great deal happened. The engine was up to temperature, yet still sounded like it does when cold, and felt similar in terms of power too. The most worrying thing was when I could barely beat a low model Fiesta in a quick sprint between lights.

Now as you can imagine, this was very strange considering the day before it was perfectly fine, and when I got home the engine sounded different, like a slight ticking.

Popped in to a local dealer to get their opinion, the guy there said the engine sounded fine but would need a diagnostic to be certain. Mentioned about a dephaser pulley, which will be expensive.

So what I really would like to know, is if anyone has had a similar issue, and if so, what was the cure?

And does the cam belt need redoing as part of the dephaser pulley being changed?

Sorry for the essay, just looking for the views of people that know about my car!

Where was ticking coming from? Prone to manifolds cracking and that can grow a spanner in the works.

Possibly a cam position sensor ?

The ticking sounded like near the top of the engine. But like I said, the guy from Renault said it sounded fine, so I'm not sure what to make of that?

Yeah I hope it's not a crack, might be fairly expensive lol

Also, flexis brake on the manifold and this causes a big flat spot at about 2.5k revs.

It does seem like a similar problem. That guy mentions the problem being intermittent on different days but so far I've only driven it on one day. I'll have a look at cleaning the sensor when I get it back

Ok, so a quick update:

No faults stored when it had a diagnostic check.
Just tried a 0-60mph and it took 10 seconds, so not good.

Gonna be checking the spark plugs Friday to see if they're dry as a friend of mine reckons it could be fuel pump.

Any other thoughts?

what did you plug it in with?

Took it to a main dealer

Plugged the Bluetooth reader in again, reckons I currently have 140bhp.

There's also absolutely no kick after 4,500rpm like there should be.

Will this be anything to do with vvt?

How can it tell you have 140bhp??

I used the Torque Pro App on Android. Obviously taking it as not 100% accurate, but it's taking 3 seconds longer than standard to get to 60mph, so that level of bhp drop seems plausible

have you checked the manifold flexis? Although to cause the symptoms you mentioned would imagine it would be pretty broken (which you should notice)

I've been assured that's not the problem as its not blowing, exhaust sounds normal. Had someone test the air/fuel ratio earlier and he said that was perfect, so his thoughts were either something to do with vvt or cams..

Maybe you should get the timing checked?

has anyone actually looked at live data on it?

Yes, I've had a Bluetooth obd reader on it a few times getting live telemetry. That's how I've got the bhp and air/fuel readings

 

[bloke]

I mean fuel trims, lambda readings etc.
