Is there any Check Engine Light on? Your car has On Board Diagnostics (OBD2). A 16 pin diagnostic socket under the dash allows a scan tool to be attached to interrogate the on board computer in your car. A professional grade scan tool reads stored trouble codes, pending trouble codes, looks at live sensor data so you can look at a sensors performance and output signals without having to do intensive testing at each sensor, (cheaper scan tools have limited capabilities and may only read the trouble code stored). As with most things automotive it's best to check the basics first, check for vacuum leaks, fuel pressure and delivery volume. Verify engine mechanical integrity (even compression on all cylinders sufficient intake manifold vacuum at idle, ect....) before looking for complex problems check that the basics are sound. You may have an engine misfire which could be fuel, ignition or mechanical. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect....
