Having problems with your 2007 Chevrolet HHR Special Edition ?
When should do tune up 2007 97000 mile car now gas mileage is going down i drive about 90 mile a day
Modern cars don't really need "tune ups", but spark plugs and ignition systems should be inspected every 30,000 miles, air filters and PVC valves every 12-15,000. Fuel filters every 60,000. All cars vary but if it's been a while since you've had your car serviced, bring it to a good repair shop and have them do a thorough inspection.
It is not needed to tune up.
