88 rx7 turbo
 

just two days ago my car started to putter and stay at 4000 rpms its fine till it its that 4'rpm mark and in nutrual it will go higher then 4 but all the way to redline im thinking its a timing problem what do you think and is it an easy fix.

things to check: tps, grounds. But before you do anything go to the FAQ (its the top thread in this forum). It will help you with just about any minor-major problems you might have with ur car.
