Stuttering Tr!

[ArthurPewty]

Hi guys...

A few months ago some of you might remember that i had bought a 2010 Auris 1.6 TR. It has had numerous problems (clutch, bodywork, water in the boot) but now i have a problem the dealer cant find...just wondering if anyone else has had it!

During normal driving it runs fine but the intermittent problem causes the engine to stutter and lose power just when you need it. At around 3~4k on the rev counter, when you accelerate to overtake or make good progress on a motorway sliproad for example. I have experienced similar in previous cars when there has been a coil pack problem or had a faulty sensor of some sort. When i have had this the engine management light has come on, but this time, nothing!

Any advice would be great as the dealer is stumped! Otherwise i will just have to wait for it to deteriorate and see if the management light appears!

Cheers people :)

Drove 330 miles to Leicester and back yesterday...car went fine...until leaving the M5 onto the M50. suddenly no power when accelerating, lumpy, sluggish, like driving with the handbrake on!...It wasn't btw ;) It carried on for 30 miles or so, got to Ross on Wye and power aplenty again! You know what its like when you go to Mr.T...the car is always on best behaviour :(

Sounds like coil pack like you say but no warning lights.

Intermittent fuel starvation because of contaminated fuel or debris in the tank - something like that?

Tank vent system working OK?

Interruption of the air supply under high demand eg collapsing air filter hose?

Maybe car just needs a good thrashing with a tree branch a la Fawlty Towers.
