Performance Troubleshooting

How do I know if I need to clean my injectors?

Dirty injectors cause several engine problems (or “drivability problems”). Problems like poor gas mileage, check engine light, hesitation, stalling, surging, pinging, slight overheating, or lack of power can be caused by dirty injectors.

A quick and easy way to tell if you need your injectors cleaned (“rebuilt”) is to read through the following list:

  • Are you getting a tune up?
  • Do you have over 80,000 miles on your engine and use poor quality gas?
  • Do you have over 120,000 miles on your engine and use good quality gas?
  • Have you lost some performance, pep or gas mileage?

If you answered “yes” to any of the above, then you need your injectors serviced by us. We have partnered with shops all across Las Vegas to allow them to give you that extra boost at tune up time. Brick and mortar shops as well as mobile mechanics can save you serious cash when repairing your car.

Are you working on your own car? Read on for some general advice to help you figure out if you need injector cleaning.

Troubleshooting drivability problems isn’t hard for a mechanic and can be relatively simple for non-mechanic types with some basic instructions. Follow these steps to eliminate the other possible causes of poor performance. After you have gone through the steps and your engine is still running poorly, then get your injectors cleaned.

Depending on what kind of gas you have been using, you might need to do an injector cleaning any time after 40,000 miles. We already know that pouring cleaner into the gas tank doesn’t work. This means you have to pull out the injectors to get them professionally cleaned by us on our machine.

  • Check your computer codes (many auto parts stores will do this for free) and fix the codes first.
  • NOTE: Downloadable PDF of common codes that are related to bad injectors is OBDII-codes.pdf
  • Check your spark plugs, wires, fuel and air filters, PCV valve, vacuum hoses and fuel pressure.
  • With your car in park and the emergency brake set, rev your engine to about 2500-3000 rpm. If the rpm remains steady with no surging or decrease in rpm or loss of power, your catalytic converter is probably OK.
  • Check your transmission kickdown to see if you aren’t mistaking performance problems for transmission problems.
  • Check and clean if necessary your throttle body and intake.
  • If possible, do a valve leakdown test to see if you have worn out valves or piston rings. (after 150,000 miles this becomes more important)
