Re: Vacuum Hoses
Any time any vacuum hose is easily removed , it needs replacing straightaway as it's leaking vacuum and this is always a bad thing .
Periodically you should give any hose under the hood a slight tug when the engine is off ~ if it easily slips off without twisting , it is bad and needs replacing . Most folks never give the various vacuum hoses any thought until it rots completely away and falls off ~ this is a serious mistake as your engine doesn't like vacuum leaks of any sort . EGR valves are a mixed bag ~ older models tend to have a vacuum source to them as soon as the engine starts and this causes driveability problems , mostly flat spots off idle (hesitation) . If you don't want to disable the EGR , choose a vacuum source that only provides a vacuum signal off idle . -Nate Quote:
