I have had several things replaced on this car already. Taken to three different shops but I don't have the credit to get a new car. I've gotten ignition coils done, spark plugs done, fuel filter done (air filter and battery were already done a few months ago), I think it's called the idle sensor done. My ETS off light has been on since I've had the car but I don't think thats the problem, I've also had an oil leak somewhere in the head gasket. Been told it could be a vacuum leak or timing chain, both have been checked. Maybe one of my sensors? But I don't know enough about cars to which one it could be. I'm to broke to keep playing guessing games...help?
