General Spark and HT leads

[Adam1984]

I have just checked under the air inlet and looked at how my HT leads where fitted.

The are connected in standard order 1 to 1, 2 to 2, 3-3 and 4-4.

Although I have been told my engine uses a wasted spark principle, do they still need to be connected in a certain way.

My coil pack for my car is a single one. See image attached.

My engine and car is a petrol 1.2, 2015 reg, and engine code: 169A400

Thanks

Would you like to cross-connect them, or what are you thinking?
The physical length of the leads wouldn't allow you to connect them in any other way even if you want to, so this is the correct way. This is the way!

I seen this on Google, so I presumed this was the right way to fit.

I wouldn’t use Google AI because it’s generally a load of rubbish. But also you don’t have a 169 fiat panda

Yes but my engine code for my panda is: 169A4000.

Thanks

There is talk about 'distributor cap'. You don't have that. That's old school. On yours the ECU fires them up in the correct order 1-3-4-2, you don't need to cross-connect them. But... you can try, if you want to. If you really really want to.

Yes that’s right but your car is a 319 not a 169 Fiat panda. Essentially don’t go by google AI. Do you have a problem- I thought your car was all OK now?

I just think my car has really slow acceleration and lack of power. Sometimes it is hard to change gears, but not always. But I am on 63000 miles and never had the O2 sensor changed yet.

I am also getting what feels like engine surge when the car is idle.

 

[Mike1alike]

Did you ever cleaned the injectors?

Did you ever cleaned the injectors?

I used Cataclean about 2 months ago, but am going to use forte petrol advanced cleaner and forte injector cleaner on my next fill.

Unless the injectors are easy to clean myself a novice with car work.

Do the oil pressure reading, see if oil pump delivers good.

And is the oil pressure reading done on MES

 

[Mike1alike]

No. You have to connect a pressure gauge instead of the oil pressure sensor. Get that done at a garage, it shouldn't be expensive.
Using MES, you sould check if throttle body and pedal are transmitting the correct data for their position.

 

[Adam1984]

Thanks and is the oil pressure test called a compression test? Thanks. Will look at them two in MES tonight

 

[Mike1alike]

No. It's called oil pressure reading.
Compression test measures the pressure made inside the cylinders when the piston closes the space (it's at its highest point inside cylinder called TDC - Top Dead Center). To do that you put the pressure reader instead of the spark plug, block the fuel and spark delivery (by disconnecting the crankshaft positioning sensor or the ECU connectors) and rotate the engine with the starter motor. Haven't you measured the compression on yours? Low compression does make the engine to not run at its best. What's the mileage on yours?

I haven't done either of these readings on my car. It's on 63160 miles.

 

[Mike1alike]

On that mileage the compression should be good, but a reading will tell you exactly how it is.

I'm getting a severe case of deja-vu... Adam has been here before. Adding to your commentary @euroben lost spark systems just don't care about firing order assuming this is the case for the later FIRE engine (1.2) as I run a twinair not 1.2.
