could anyone advise me on were i can locate the iat(intake air temp sensor)or engine temperature sensor and does anyone have any idea were i could locate a workshop manual for the 1.6 sx as haynes could never be bothered to print one well thats what their website claims anyway...thanks in advance

There's a Porter manual for the Marea, but it covers other cars too.

Looking for the air temp sensor..... not to fit an ebay resistor mod, perhaps?

visit this link below if your Marea is 1.6 auto
