Thanks for the question.
The parts will not be hard to get. Any local auto parts store should have all you need, including....
- fuel filter ($10-$30)
- spark plugs ($3.00-$7.00 each)
- wires ($30.00-$50.00)
- cap ($27.00)
- rotor button ($12.00)
- pcv valve ($2.00)
- air filter ($12.00-$40.00)
* All prices based on AutoZone.com, may change.
Labor will depend on whatever shop does the repair, but most, if not all of these things you can do yourself.
Sure, if you have some mechanical know-how and a decent tool set, you should be able to perform the repairs.
All the parts I have listed above are typically for a regular tune-up, minus any fluid changes, like oil, trans, rear axle, etc.
As well, all parts listed are available for purchase at most local parts stores, or even a GM dealer (GM prices are usually higher). If the parts stores do not have one of the items, the can order it and usually have it the next day.
If your check engine lamp was one, then a scan would be needed. As far as anything else, I cannot be sure about since I do not know what brand parts they used. Also, you have to figure in the labor time since a shop performed the repair. This weekend, I spent $300 in tune-up parts for my own car, but I didn't pay for labor. To be honest, I do not think you got "taken for a ride".
Thank you, XXXXX XXXXX it. Glad to help.
Please let me know if there is anything else I can do to help.
