Misfire

[Neal H]

Hi,

My 182 Cup has developed an intermitant misfire. Basically it normally occurs within a mile or so of setting off. The symptoms are cruising along gently on a light throttle, press throttle and nothing happens apart from the engine starts stuttering. It usually recovers and continues the rest of the journey normally, but on one occasion conked out when I had to pull up at a roundabout. It restarted at the second attempt, but the tickover was very erratic for a short while and I noticed the temp guage needle fluctuating around a lot, before it settled down and then ran okay. I have noticed the temp needle wobbling about from the 'normal' a bit even when everything appears okay.

It's booked into the garage on Monday, but I am not overly optimistic that they will diagnose the fault as no warning lights have lit up when it has started to play up and I am sure when they just plug it into the diagnostic computer it will just come up with the standard 'no fault found' response.

Anyone else experienced a similar problem, so that I might be able to give them a few pointers on Monday?

Thanks for any help!

Neal.

MINE DID SOMETHING VERY SIMILAR WHEN I FIRST GOT IT TOOK IT TO RENAULT AND THE REPROGRAMMED IT AND ITS BEEN FINE SINCE BUT THEY HAD TO RE LOAD THE ORIGINAL ECU MAP.

mine did it occasionally, and then it got pretty severe - it wouldnt accelerate, and if you tried, it went mental and started backfiring lots..

turned out it was just one seriously fouled plug - changed all plugs and it ran fine again not only that, my emmissions light went off too! (de-cat)

Check plugs/leads, coil pack (do 182s have them?) most common cause of misfire really.

Mine did this, allbeit a 1.2, but it was the spark plug leads so its worth looking at them.

Thanks for the feedback chaps!

For the record, the garage claims to have fixed it. They said it was a faulty water temperature sensor. This does fit with the erratic behaviour of the temp guage, but whether it would cause an engine mis-fire is another matter!

Time will tell I suppose!

Thanks again.
Neal.
