$600 is a lot for that; it should be $300 or less for plugs, wires, cap
& filters. If you want to try it on your own, get the FACTORY Shop
Manual from eBay (used) or from www.helminc.com (for new). You should
also have a set of socket & open-end wrenches, a test light, a torque
wrench, and a code reader. The first thing I would do is put in fresh
spark plugs, which go a long way toward helping a car start. Another
design weakness preventing a quick cold start is the Idle Air Control
valve that wears out over the years & miles.

my problem is that on some days my van wont start so im thinking
distributor cap. now i took it to a repair shop and they said that was the
problem and also i need a tune up and wires and they quoted me $600.00 to
put new wires and new cap and air filter and fuel filter so my question is
$600.00 to much to pay?.and is there any way i can do it myself with a book
or anything else. by the way i am a woman could that be why the price is so
high. please help.
