Question about 1999 Chevrolet Venture
I was told this van has plastic gaskets that go out alot easier than the standard gaskets. They will make your van overheat. almost had to do this on mine. Lucked out and it was water pump.

I was just having the exact same problem with mine!! (my 1999 Chevrolet Cavalier)
It turned out that replacing all of the parts you mentioned, I just had an air bubble in my system and needed to run it with the cap off and fill it up with water as the engine ran and the air escaped.
Hope that helps you!

I had this same problem with my 2002 3.4L engine impala. Unfortunately, there was a coolant leak at the lower-intake manifold, caused by a cracked gasket. I replaced the gasket, water pump, thermostat, spark plugs and wires and flushed out the heater coil. Didn't find out what it was until after spending 100s on Dex-Cool. I kept refilling it for months until I got a good mechanic to fix the problem whom told me that this is a common repair on older impalas and GM vehicles with 3.4 and 3.1 engines.

Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)
