'87 Westy, 2.1l, automatic So, thermostat's replaced and grounds and hoses supposedly checked, but here're the symptoms I'm seeing: Cold start: Van acts like the battery's weak when I start it (it's not). Turns over quick at first, then slower, then finally jumps to life. Idles up and down at a low idle, sounds like plugs are misfiring, until the engine warms up a little, about a minute or so. Most cars I've ever owned/worked on idle high at first to warm the engine up, or something. What is the cold idle speed supposed to be on a Vanagon? Once warm: Idles around 900-1000 RPMs, idle smooths out, puts out a lot more stuff out the exhaust, particularly when it's cold out. Gas mileage has dropped from 16-17 down to 14 MPG. Drive for 20-30 minutes into town to work: When I'm ready to park it, I put it in Park (yes, automatic), and the idle jumps up to 1400-1800 RPMs for a few seconds then settles down to 1000-1200 RPMs. I was trying to keep track of all the suggestions that have been made here recently since the cold weather hit and everybody seemed to all of a sudden have idle issues. Unfortunately, there were so many different suggestions of things to check for, I figured I better ask again. Thanks for any and all help, Marc Perdue |
