Hello all,

I have just bought a 2010 Panda 1.1 Eco for my son to learn in. A bit of a temporary car, just to get him moving while we work out what comes next...

So we wanted something cheap and available. So here we are, perhaps not the best car, but it was those two things. It seemed fine on the test drive, but now we have it home it is coughing at low revs (although that's hard to gauge without a, erm, gauge!) when under load (i.e. going up a slight hill). With no service history, the first thing I thought of was the plugs and while I had the airbox off, I replaced the filter. Cleaned up the leads with a bit of contact cleaner and put it all back together. I think it is better, as it doesn't cough any more, but it still seems to really labour going up a slight hill, struggling even to maintain speed in 4th or 3rd. Maybe it is just that slow, and my expectations of 54bhp are too high?

But when it is labouring, it's like it's running slightly rough; you can feel that wobble, slightly more than the normal engine vibration, of the engine not running quite right. Reading other threads on here, people say they notice it running much better after changing plugs, but I'm not sure there is much difference (other than the cough seems to have gone).

So when diagnosing this sort of thing, what are the usual steps?

Plugs - £20
Filter - £5
Leads - £15
Coils - £30

Any more. Or a different order? Or am I just wasting money on those, and I just have to accept it as a bit of character?
 
Hello,

Connect it to MES of AlfaOBD, you might get some errors to point you to the proper direction.
Ah, good point. Wouldn't there be an engine management warning light though if there was a detected error?

I don't have one of those, but I have a generic Bluetooth OBD2 thing I bought years ago and a iCarsoft MB V2.0 which was bought for my Mercedes van a few years back. Are these things generic, or do I need one of those you mention specifically?
 
Every manufacturer is trying to make it hard to use the generic scanners and apps. In general it should connect to the engine module (ECU) of every make, however I'm not sure if it will give correct readings.

Check gendan's offer online.

MultiEcuScan and AlfaOBD are best to use with FIATs.
