Many new cars require special spark plugs, available at the
dealership, they are expensive, like $20 per, and need special
software to check the gap and are firing properly. On the plus side
newer vehicles don't need plugs changed for 100,000 miles. There
really isn't much an owner can do themself on new vehicles, there are
computerized sensors on everything, even the gas cap. My wife just
had to buy a new gas cap, something died in it and an idiot light came
on. If she went to the dealer it would have cost $120 just to put the
car on their computer and then they'd charge double for the new cap.
She had purchased one of those thingies that you plug in to a port
under the dash board and it checks all the computer moduales on the
vehical and by bluetooth sends a report to her smartphone and she can
send it to her printer. She did the printout and it indicated the gas
cap was defective, she ordered a new one from Amazon and replaced the
old one. I inspected the old gas cap but could see nothing wrong with
it, probably some internal circuitry died. Anyway with the new cap
the idiot light went off after running the engine for five minutes...
Amazon charged $28, the instruction that came with the cap said to run
the engine for a few minutes giving the module time to scan and
correct. My thought was that if you go to a full service gas station
they could easily swap your cap for their defective one... another
reason to pump your own gas or at least get out of your car and watch.
