welcome to the site, eewilliams ...

 

Thanks, wheres is it? Is it easy to change? When I fill-up with gas, my car will not start immediately; I have to crank it about 4 x's before it will start. Does the solenoid have anything to do with this? When is a tune-up recommended for my 2006 HHR? It has 186,000 miles on it and has never had a tune-up.

 

That's pretty good mileage for one set of spark plugs, might think about changing them.
