Asked by Jan 03, 2015 at 09:35 PM about the 2002 Ford F-150 Lariat Crew Cab SB

Question type: Maintenance & Repair

Our check engine light came on and either the fuel is "too rich", a fuel injector is gunked
up or something else...per the man who hooked it up the computer.

Yes it can. What code did he say was showing for the check engine light? With that code we can give you a better idea what your are dealing with.

CEL for rich condition can also be a O2 sensor.

Have the computer scanned at your local auto parts store to get the codes. Most stores will do it for free. HTH. -Jim
