Does anyone know what is this little red thing?

Also, how can i correct a bad air/fuel mixture on a mk1 punto (1.1 engine and i get 10l/100 fuel consumption(23.5 miles per gallon:cry:))
 
That looks like a capacitor to me mate, not sure what for though.
 
No, not really, just had the engine cleaned, oil change, timing belt and filters.
 
I'd be checking the plugs and leads, maybe time to replace them but i would have thought you'd experience poor running before noticing an increase in consumption.

How long have you had the car? I just wondering if this is an issue that has developed while you had the car, if so has it lost power at all since the poor consumption started.
 
I had the car for around 7 months now, it runs great, no performance problems. Could it be the lambda sensor or oxygen sensor? (the car if from 95) If yes, what is the difference between these, and where can i find them or it in the car.

PS. had the plug leads changed too. In the winter time, it had a rough idle, turned out to be leaking plug lead and crappy fuel.
 
Never done more than 80 km/h, I also keep the rpm's around 2000. When i get the chance, I'm going to find that sucker, get it out, clean it or replace it, and see what happens. :cool:
 
Just musing... 10L @ 4.5L/gallon = 20/9 galls, 100miles x20/9 = 45MPG
or have I done that wrong?.
Tony.

You did do it wrong it's 10L to 100Km

However OP did it wrong also as UK gallons are different to a US gallon (us gallon would be 23mpg)
so in our money 10L/100 is 28.25MPG which is pretty crap

The sensor in the pic is the air temp thermistor as Dave said earlier on

Could be the lambda or could be badly gapped plugs from when you replaced them
 
Hey I just bought a brand new 1 of those but turned out didnt need it. Loose wire to coil pack was the problem.Paid £15.50 with postage Let me know if u want it, Its yours for a tenner I will send it free of charge cant be bothered reselling it on ebay.
 
10/100 is absurd. Check thermostat and coolant temperature sensor. Lambda probe is a possibility, but it is too often blamed for bad mileage simply because the workshop monkey only knows how to change it and has no idea about how it works. I still have the original lambda probe on my 96 1.1 (200+ kkm) and it is OK.
 
Yes, I'd look at the lambda too. If the engine idles slightly rough and you have a very sooty exhaust too, then that proves it.

But a proper lamda, either Bosch or NGK/NTK since these come with full-length wiring and a built in plug.

The cheapo ones on eBay have short wires and you have to cut your original wires and splice the two together (so you make use of your existing lambda wiring and plug).

Needless to say, it's another complication that can go wrong later. It's worth it to spend the extra and buy the quality replacement, unless you like taking lamdas off and replacing them every 6 months.
