From another post.......... Po 442......Check engine light on .....Codes Checked by a "Scan for Free" auto parts store. Quote:

Probable cause: 1. Fuel cap 2. EVAP canister or hose cracked-not connected 3. Purge or vent solenoid defective 4. Vacuum Leak at engine.

Now.. I'll probably catch someones WRATH, But While these stores are offering a Free service , They are also attempting to generate Parts sales. Everyone is entitled to make a living of course, But Most of these "Stock Boys" and Countermen" have very Limited Knowledge and experience ,in "Interpreting" what they see on the Screen of The "Scanner Behind the Counter". As evidence,And from 20 + years in the Business , The MOST probable causes of the above scenario would Be... 1)... Loose Gas Cap....Fuel service attendant or Customer Did not "Click till stop". 2)...Vehicle filled with fuel while Running... 3) Gas cap missing or not replaced after fueling Only one of these would REQUIRE a PART replacement. Tightening the cap and clearing the codes would likely rectify the C/E light. The codes can be cleared with the same scanner that was used to read them. However, customers are told this is not possible. Unless , of course you buy a part from them. Is this what Our Business has turned into??????? Mechanics , for years, have had to deal with a reputation of being THIEVES, LIARS AND CHEATS, And Fraudulent Practice like this , only reinforces these accusations.... __________________ Remember Safety first..

Hi, I have a 2003 lincoln navigator that has something wrong with it. The entire car will not rise- it dropped on its on and when we drive it to the mechanic it bounces like crazy. My normal mechanic works on asian cars and does not have a machine to see what is wrong. he thinks it is electrical bc he tried replacing some pump that makes the car rise and when he put the new pump in no air was getting to that compressor pump? so he knew it wasnt the pump but something else that is causing it to not work. We took it to the dealership and they said it could cost between $600 to $6000. What kind of estimate is that- I think they are trying to rip me off. Please help- I do not know where else to turn.
