What does the exhaust note sound like at idle?

It was actually the downstream oxygen sensor (after the CAT) that was diagnosed. Had it changed and now i'm not getting any fault codes but the problem is still there, although it has made it 50 % better and more drivable. I'm gonna swap the lambda sensors around tomorrow to see if it is the...

The tyres on my 172 FF Alloys are 195/45/16...has anyone fitted 205/45/16s on the standard alloys?

That is the best colour going! Beautiful! I do love the Trophy colour aswell, although the Trophy Recaros aren't as comfy as the FF seats!

Yeah thats what the fault code was saying...the upstream oxygen something! (Paperwork is at home!) I could change the sensor myself, dunno whether to risk it or get it checked out on thursday. Bearing in mind i've already spent £200 on changing unnecessary parts! lol

I took the car to a Renault specialist today for some answers...his diagnostics picked up a fault with the main Lambda sensor or the wiring to the Lambda. He is going to check the wiring next Thursday before we change a sensor that might not need changing, although i want to check it over...

Mines had a group N remap from JMS. Before the recent problems started it ran smooth at idle and had a better torque curve, it pulls really well from low revs all the way round.

A friend has told me it could be the automatic choke?? someone he knew had the same problem and this was playing up! would this not show on a diagnostics? god i'm at a loss!! Its booked into a Renault specialist on Friday. I do think it may be fuelling issues tho...

Does it really matter if someone wants to change their Air Filter?! What are we talking even if it is losing HP? 2-3 BHP?? I think some people are a bit die hard on this forum!

Ashford in Kent. I just thought Renault might have a better idea on diagnosing the problem, plus its just down the road from me. £93 / hour tho!

Yeah he was looking at the live data, checking everything. I suggested the lamda sensor but he said it would be showing up on his screen. Sounds like you know your clios, possibly the lamda if u say it never shows up. could be anything, think i'm just gonna have to take it to Renault. £500...

starter motor?

b****cks! replaced the brake sensor switch and no fault codes now, all electrics are fine. Clio is still running wierd, cuts in and out every now and then, hesitant then pulls, very strange. Its as if the fuel cuts out then back in again, but its worse lower in the rev range and better...

Well I had it plugged in to a diagnostic machine and it had 3 fault codes about the brake switch sensor. He cleared the codes and when I started the engine it ran normally again. After driving it 3 miles home it very slowly started missing and eventually started running rough again. The mechanic...

Has anyone noticed any power gains thru de cat plus exhaust? im a bit reluctant to get anything at the mo cos im driving to Newquay from Kent in a couple of weeks (6hrs of exhaust note!) I wouldnt mind some lumpy fast road cams at some point tho!

I don't know what fuel your running on! Mine wasn't/isn't lumpy at idle, its quite smooth!

Advice to anyone having engine problems....get a diagnostic test! After spending £135 replacing Coil pack, leads and plugs it turns out i have a faulty brake switch! Gonna pick one up from Renault on Monday!

Hi all, my Phase 2 172 FF has developed a lumpy/rough idle and up to about 3K then seems normal after that. I've changed the coil pack, leads and plugs and there is still no change. When i removed the plugs there were no bad signs, they all looked ok. I'm wondering if its anything else...

My car is doing the same at the mo, its really lumpy and spluttery below 3K, seems to rev freely above that, also getting a spluttering and popping from the exhaust. I've changed the coil pack and the plugs, all genuine parts. For some reason i opted to not change the leads so they are next, if...

I see...I will check later today. Got to remove the inlet manifold to change the plugs today, does anyone know any does and don'ts with this? Has anyone ever heard of a K&N panel filter messing up an air flow meter due to the oil on the K&N?

Hi peeps, i have recently purchased a ph2 172 FF in Iceburg Silver. I love it, but i don't think it loves me yet as i'm going thru the process of changing the coil pack, ht leads and plugs to sort out the lumpy misfire which started today! Anyway the reason for this post... did the 172 come...
