on the stilo there is two lambda sensors as far as i know. 1 at the top ov the engine at the bk n 1 down below near exhaust fittin. i need to replace the 1 below but have been told theres a few different sizes. can anybody help me n tell me the size ov the lambda.

ePER (the Fiat parts catalogue), only lists one post cat. lambda sensor for the 1.6 engine. Part number 46750243.
.

thanks Davren much appreciated.

If this may be of some help...
...I remember someone once said that basicaly only difference between them is in cable lenght (in case front one that's arround 35 cm length, while back one should be a bit longer - about 60cm).
The front lambda sensor has catalogue number 46762182, while after sensor is as Davren reffered.

And, what are the symptoms anyway ?

ye any advice is gud. cheers. well ive found some diag forms in the book n guides that came with car and there was a print off that lambda sensor needed sortin. the top 1 is dun n new but the bottom 1 isnt its old n rusty. the car keeps comin up with engine fault so im just gonna give it a blast. also air bag light. its the mrs car, but i think stevie wonder advised her to buy it :banghead: its had a brand new battery on monday, n ive got new sparks, oil/filter n air filter ready all im gonna do asap as it dies on throttle at 4kRPM so goin for cheap ideas first. O n the air box is Ruined lol. After the way she drives shes prob best off with it not runnin prop and she ay usin my Abarth
