Anyone had a 1.5l Ecoboost problem

Just curious really.

Wife has a 17plate Kuga (mk2 Facelift) from new with the 1.5l EcoBoost engine, auto box, AWD, and it's been fine for 13months.

Drove it around 50miles on Monday without any issue, got home and parked up. Went out again on Wednesday and it sounded like a diesel van. Barely made it down the road as it was misfiring so bad the whole car shook even at idle and constantly tried stalling on the overrun.

Chucked Forscan on and pulled a code for cylinder 1 misfire so got on to the dealer. Was taken away on Saturday after MUCH pissing about by RAC (who should have taken it on Thursday but that's another story) and found out today that the fault is not electrical (plugs, packs, ECU, and injectors are all fine) car was serviced only a few weeks ago with 4,000 miles on the clock and hasn't missed a beat since till Wednesday.

Not too worried about fault finding as the dealer are on it and will return the car asap I'm sure, just wondering if anyone has heard or experienced any similar issues to this?

Hi Peter, ah, bad news that cylinder is damaged.

There is a remote chance I might, repeat might, know an engine specialist that may help with std or oversize pistons.

It will be no trouble for me to ask but it will not be until Monday when the business opens, I will ask on Monday.

Meanwhile, if you want to, PM me your full eng info, spec, bhp etc and your vin number and year

I have a Focus with the 1.5 4 cylinder EB engine and have "funny" issue with it , if revved over 4K sometimes (yeah only sometimes) the car will hesitate like a misfire but no misfires recorded and no faultcodes stored , also it consumes about 2 litres of oil in 8000 km , also one time when giving it an italian tuneup it started to sound like popcorns popping in the cat , I got scared and slowed down and when I accelerated again the cloud of blue smoke the car made must be some kind of record so my guess here it filled up the cat with oil or something.
And sadly this sound like the beginning of the end of that engine , my car has 86000 km on the clock. Did you also have the slight misfire symptoms and oil consumption before the catastrophic failure ?

Sorry I haven't replied here, never got a notification.

There was no obvious warning signs to it. The 1st engine had a strange rattling/whoosing noise (bit like beads in a wooden tube rainmaker type noise) that happened very randomly. Parked it up for a couple of days and when we went out in it the next time it was idling rough and shaking quite badly.

2nd engine we noticed a rotten egg smell on the motorway which we assumed was the CAT. Got us from Worthing to Devon just fine though, spent a week driving round and headed home. Was only when about 30min from home we came off a roundabout and it felt like a very harsh gearchange, but no warning lights/smells/smoke and drove fine until we got into stop start traffic and the rough idle, shaking and stalling started.

The only other thing that we can remember is the MPG dropped from about 22mpg down to 17mpg on the same trips.

Both times the RAC came out and pulled the codes and both times it had logged misfires.
