	You are quite correct, it could be any other sensor. You need to take it to a garage that can read the diagnostics. It could be crank/cam/temp/O2/MAF sensor at fault or blocked EGR system, split inlet hoses, faulty spark plug or ignition coil. Trying to pin point any of those are a nightmare without a diagnostic check. A diagnostic check is usually a standard fee of 1 hours labour. Depending on the age of the car it could be that the catalytic converters are breaking up and impeding the flow of the exhaust gasses. Is it an automatic per chance? Andrew
