After driving in highway for 15 minutes or longer, the engine spee
meter starts moving back and force, i can feel the engine RPM surging
the vehicle got some "pulsing" effect, after a while , "pulsing
symptom disappear, but feels like the acceleration become slugish
since engine speed meter still moving back and force, (well, most o
the time , stays at 0), i don't know what RPM the engine is at.
It seems like i have to shutdown the engine, let it completely coo
down, before the engine meter come back to normal again. And in ho
weather, this problem happen pretty quick after i get on the road.
while ago when the weather is cool, it didn't happen on my way t
work(30 miles high way).
Can anybody give me some hints on this?
Thank you!

what's your coolant level? look inside the radiator when cool, do NOT
rely on the level of fluid in the expansion bottle.
