Buy a new one, or buy the parts and fix it yourself.. Generally labour is always going to cost more than the price of the product.. They of course want you to buy a new one anyway..
Sensor Can this be the issue? Well, basically what happens here is, I have been having some problems with the car intermittently running rough, but I have only noticed it when the car sits for about 2-3 hours. Any longer, or any less, it is fine. The car ONLY acts up when it sits for 2-3 hours...
