WHAT IS MAKING MY 1995 VOLVO 960 RPM GOING UP AND DOWN UP CONSTANTLY WHENEVER I'M ALWAYS ON A RED LIGHT?

Question

THANK YOU.

Answer 1

throttle body assembly coked or fast idle valve and the most easy thing to do is check your antifreeze level or vaccum leak

Answer 2

My 2001 S60 did this in park. Its just a software issue in the ETM. If your car has one idk.

Answer 3

could be a few things. if you have a engine light on. have a mechanic check it out.

other than that sounds like a ECT sensor(engine coolant temp) or a dirty throttle body

Answer 4

Have the air mass meter checked for proper air/fuel mixture, the ecu is trying to compensate. In addition check for vacuum leaks.

Answer 5

in consumer report i heard volvos are cars that your not supposed to get...-too late. my mom has a volvo 850 from 1995 and so many things are wrong with it. although its 13 years old..still.

Answer 6

yeah they are right , might be some air in the system  U have to bleed the system and it prob. does that in park also,,,
