2002 Focus banging into 2nd and 3rd
First post but have used the site for a few years. My wife has a 2002 Focus SE Zetec with 187,000 miles and was having a problem with idle. Took it to a independent garage because I didn't have time to deal with it. I have a 2002 BMW X5 with 220,000 that takes most my time. First garage put a new passenger side motor mount in it and ran some sea foam through it. It acted OK for about 2 days. The rough idle came back. To be honest I don't know if it ever went away. It wasn't that bad so i decided to just let it be. It finally started getting worse so I needed an inspection and front end alignment anyway so I took it to another mechanic (independent) Its not throwing any codes by the way. This mechanic charges me 3 hours of setting the timing @ $70 an hour. The car was running the same. I blew up at that price and just took it home to look at it myself. I replaced the other two motor mounts and took the car for a spin rough idle and no banging into gear. Then started messing under the hood an found that the PCV hose had collapsed and had a hole in it. Replaced the hose and it now idles perfect in park. Put it in gear and the idle is rough. Took the car down the road and now after just replacing the hose and now the car bangs into second and third so hard the belt squeals when it happens. Any ideas what might have happened?
