I just bought the car with 118k miles. I had the Rad. Coolant flushed, tranny flushed, brake fluid flushed. I am fixing the cracked manifold this weekend. But, iam a maintence junky and feel that replacing the spark plugs is safe. Any advice??? I need the location sequence and any ideas for good plugs for this car..never had a GTP.
At many auto parts stores you can buy a Haynes do-it-yourself manual for your model car, with step-by-step instructions, and basic explanations at the beginning of each chapter. If it is not in stock, you can order it online by searching on "auto repair manuals" on Yahoo search. In the front is a section on "Troubleshooting" that guides you step-by-step to find causes of most engine malfunctions based on the car's symptoms.
db667089 says: you can check http://www.alldatadiy.com. For about the same price as a Haynes or Chilton's repair manual, you can have online access (for a whole year) to model specific info for your particular vehicle. This is the same info that repair shops use. They have great wiring schematics/diagrams.
Also, for about $15 for a one-month subscription, you can get the factory manual, downloadable (careful! Mine was about 500 pages!) or viewable, at http://eAutoRepair.com.
