I have replaced the engine with a used one. everything works good on it but it is just the rpm is high 2000 rpm in fifth gear going about fifty mph. And normally it is 2000 rpm at sixty mph when the old motor was on. And I am just looking for what can be the problem. Thanks

scan for codes and check fuel pressure with a gauge as well as look for a vacuum leak first. you may need a professioanl to scan it with his scanner as it may be something auto parts ones cannot read.
