It’s impossible to say. Modern cars use an ODB-II compliant engine management system that monitors several sensors around the engine and produces any of hundreds of possible trouble codes when it senses a problem. Just guessing and throwing parts at it can get expensive. Get the codes read. If it is here in the states, there are many auto parts stores nationwide that will read the codes for free. Get the codes in a format like P0131, post it here, and we can offer more sound advise. ---
