Engine Performance Analysis and Check Engine Light
When your warning lights are on, or if your vehicle’s everyday performance just doesn’t seem right, remember that our technicians have the best training and the best test equipment at their disposal. They’ll analyze and diagnose the cause correctly and get your car running right again. Our on-line-based information system provides current technical bulletins and keeps us up-to-date on the latest repair procedures. The Pellman’s “Test, Don’t Guess” philosophy insures an accurate diagnosis for today’s increasingly complex vehicles and prevents the installation of unneeded parts.
Here are some typical symptoms that could indicate engine performance problems:

  • hard start or no start
  • stalling
  • poor fuel economy
  • rough idle
  • power loss
  • erratic transmission shifting or poor acceleration
  • “Check Engine” light is illuminated

Some of the above symptoms could indicate a more serious underlying issue, so it’s important to have these items addressed. Fixing the problem now can save you money in the long run.
To help us diagnose your problem faster and more efficiently, it helps to have as much information as possible. Please print and fill out the following drivability worksheet and bring it in with you when you drop off your car. It can also be faxed to us at 303-998-0091. Additional forms can be found in our forms library.
