Greetings, and thanks for your time! My 1990 Volvo 240DL idles a little rough, runs ok (I think it does, it's a friends car, and I never drove it until this problem started) and then after a short drive it revs real high when put into park. Here's the back story: Car was hard to start and would die without revving the throttle a bit. We've replaced the fuel relay and the fuel filter. My friend also put in some oil before I got involved (Maybe too much, there's a puddle in the driveway, but I see no oil leak now) . So it's much better now, but still unhappy with something. Any troubleshooting tips would be much appreciated!

I did not have any problem installing the water pump. It took about 2 hrs.
Just pay attention to how the old one is designed and comes off the block.

Tap out the tube from the water pump to the heater core and replace the gasket in place with a small amount of gasket sealer to hold it in place.

use a lever to raise the water pump to squeeze the larger O ring into place so you can start the first bolt and you'll be on your way to the finish line in no time.

This is not a job for your average home owner do it your selfer. a little more than basic machanics is sugested to do this one.

SOURCE: when im idling in park or neutral engine revs high

These cars used a motor underneath the intake manifold to control the idle. The crank sensor may need to be checked, the signal to the motor needs to be checked. If you have a seperate control module (passenger footwell, right side, behind the plastic) under the main fuel control module, you may want to check the wiring on that as well. The Haynes manual for these vehicles describe the system very well.

Welcome to Fixya

If you already tried the paper clip method then most likely the tail light assembly circuit board films or wirings that is having the problem. Use a test light to check for power at the tail light assembly, while you have the switch bypassed.

Thank you for using Fixya!
