Looking for suggestions
Just today I was driving my wifes 240. We stopped for lunch and when put her in park I noticed a very high idle about 2200 RPM. I went in and had lunch only to return to a NO START condition. I could tell it was flooding with fuel due to the smell. But I pulled the distributor cap off and turned it over I had good fire in cap.
I though it must be a throttle position sensor or some type of air flow issue.
I depressed acceleror to the floor about 10 times, tapped on the Throttle valve switch with a wrench. And she started. Still with a high idle though. I get home pull in and get ready to park and High idle goes away.
My thoughts are that it maybe the coolant temp sensor, or the throttle valve switch. This is my first Volvo so I have not got the Volvo experence but I have had many BMWs in the past and the fuel and ign systems are very similar. But is there something I else I need to check.
Does anyone have any other suggestions.
Thanks
