Question about Acura Cars & Trucks
Revs up to 1500 rpm and down to 1000 rpm after starting what causes this?
Cars are design to run at a higher idle at start up to warm them up quick. There is a sensor that reads water temperature and tells your car's computer how fast to idle. Your RPMs seem slightly high but not out of the norm. Does idle ever drop to around 600/800 after about a minute? If not, your engine temperature sensor maybe defective.

a vacuum leak will cause a high idle due to he fact more air is entering the engine which the computer will compensate by adding more fuel. also, a faulty fuel pressure regulator will increase fuel pressure delivering more fuel than required.
look for broken or detatched vacuum hoses. check fuel pressure; 30-50psi
