Hi all,
Been a while since I have posted here, but still driving Swedish wonders. Can't imagine driving anything else.
Acquired a real nice 07 XC-70 that had only 104K, and never, ever seen road salt. This is a big deal to those of us in upstate NY. Been working my way through some of the things one finds on a used car. (Timing belt, serp. belt, oil change, new spark plugs, IPD belly pan, etc.) One that has me a little puzzled is an intermittent rough starting issue.
The car always starts and runs great. What is puzzling is how it starts. Many times it starts like any good XC-70, a couple rotations of the engine and it starts smoothly. However, sometimes it cranks a bit more and starts a bit rough. Immediately smooths out once it starts. I just began to notice that when it takes more than a few rotations to start, the speedometer will briefly go way up before it starts, then when it starts, it is running at normal idle speed (around 700 rpm). Not the usual 1500 rpm when it is cold. If I give it a little gas, the idle speed will got to 1500 rpm and hold there for several seconds as is normal for a cold engine. The rough starting also occurs with a hot engine, though without the high idle, which is normal on a hot engine. Another symptom is when cranking the engine (both cold or hot), sometimes the starter is fighting against what seems like a strong kick back. The engine rotation almost stops briefly before rotating again. Eventually, the engine starts and runs fine.
Any ideas out there?
Had our first snow today, and want to get this resolved before winter settle in for good.
