Just when I thought I'd got it all sorted it's started playing up again. This time it's showing a MCSF at high revs, the symptoms are.... She runs perfectly all the time at low to medium revs and with the odd blast up to about 5500RPM with no problems at all, when I get her on a decent straight though and give her some welly in a straight line she'll start hunting slightly at about 4500RPM and by the time I'm getting towards 6000RPM the computer will be screaming it's head off. After I've slowed down and the bleeping noise has stopped the MCSF fault will display on the computer for about 10 start ups and then vanish until I have to overtake a line of traffic again when we start the whole procedure again.

The car is a 2002 156 1.6ts, It's had new variator, cambelt, aux belt and tensioner, battery, temp sender, MAF sensor, plugs and engine wiring loom.

Anyone got any idea's?

What's your thermostat like? It happened to me once when my thermostat was buggered and the car was running cold.

Thanks for the reply... It's had a new thermostat as well, I forgot to mention that. My car is starting to resemble Trigger's broom off fools and horses. :lol:

Bump. Anyone

best bet is to get the ECU error codes read the MCSF error can mean so many different things, you can do it yourself by getting a OBDII cable from somewhere ( got mine from ebay ) and download a copy of FiatECUScan or if you're not confident with that sort of things pop to a local specialist we have several in the East Mids depending on where you are i myself use www.alfatecnico.co.uk but there is also http://www.afh1.co.uk/ or http://www.peakalfa.co.uk/ or some people also recommend http://www.eurocarcare.co.uk/ any of these places should be able to help you no worries, as i mentioned though i myself prefer Alfa Tecnico at Huthwait

Yeah, the thing is that I'm already into Lewis at Alfatechnico for about 2 grand of my hard earned, variator, belts, drive shaft components, brakes, electrics etc etc, the car's probably stood me at around 3k in repairs all in all on top of the initial cost 1450 to buy it back in February and I'm trying not to spend a whole lot more on her until I've at least got Christmas out of the way. I just wondered if anyone had any idea's that didn't involve plugging it into a computer at 35 quid a go and then having to pay an arm, a leg and possibly the shirt off my back as well just to get it running right (again).

get your ecu codes read ,could be coil pack playing up......has it started playing up since belt service ie soonish after ????????

 

[19frost59]

I only noticed it about a month ago and I had the belt service done about 3 months ago, but up until a month ago my commute to work was all 30 and 40mph speed limits so I didn't really get a lot of chance to 'explore' it's straight line performance too well. Since I've changed jobs though my commute now consists of ten miles of dual carriageway so in answer to your question I don't know how long after the belt service the fault began. Sorry.

problem can be multitude of things .... coil pack. spark plugs..maf...catylitic converter....mis timed engine ,cam sensor,,air filter ,,, but codes need reading to diagnose it properly

 

[19frost59]

We can rule out plugs, maf, mis timed engine and air filter because Lewis did all of those along with engine wiring loom, thermostat, water temp sender and no'2 lambda probe, looks like it could be a coil pack then?

never rule anything out until codes read:thumbs:

+1 it's impossible to say for certain aqnd much cheaper to get error codes read and get an accurate diagnosis than to just go changing parts willy nilly in the hopes of curing the issue
