2000 V70 MT with oddly low RPMs

Post by brunocerous » Wed Nov 20, 2019 9:37 pm

Hello, all!

My '00 V70 MT has been nonstop with the P0600 code ( viewtopic.php?f=1&t=90151 ) lately and acting strange with RPMs.

If I'm coasting to a stop and put it in neutral, the RPMs drop down to around 300-500, but only until I come to a complete stop, at which point they return to the 900-1,000 RPM range.

Any guidance on whether the P0600 and the RPM issue is related would be much appreciated. Or is there something else I should be checking?

Occasionally, I'm also stalling upon the first start of the day and occasionally get "lawnmower syndrome" for a few tries afterward. I dig my 5-speed but wonder if it's coming down to new ECU time.

Thanks for any insights!

You got your selfavacuumleak there, partner

Do a vAT inspection of all the vacuum lines, and include the evap system under the car on that inevitably too,

The run down low rpm tango is classic unmetered air into the system.
