My escort is rpm over 3k when it starts and check engine light comes on. i get codes 116, 412, and 411..what can i do?

Is the check engine light on? Even if irs not i would still have the codes read. Sounds like a bad crank or cam sensor but it should set a light

Check the ignition wires and the module

What is the year, make and model?
How many miles on it?

You should know that when the check engine light flashes ENGINE DAMAGE can occur!!!

When you excellerate and the rpms get over 3k or so. Have you checked to see what codes are causing the light to come on?

It is an indication that the computer has detected a performance or emissions problem and has taken steps to prevent damage by not allowing the engine to rev higher than 2K - 3K RPM. There should be a check engine light on as well. You need to have the codes read to find out where the problem exists.

There are literally thousands of codes that can cause the check engine light to come on. There is no way to guess why yours is on based on your symptoms. Many auto part stores will scan your engine computer and give you a print out of the codes for free, unless you live in CA. We would need to know what these codes are to give you an accurate reason you are having issues. FYI, modern engines won't rev past 3000-3500 rpm in neutral. This is to prevent engine and torque converter damage.

Take the car in and get the code checked. Then you may have an idea what is up

I've got Hyundai Lantra 1.6 year 2000. It's take time to start when it's hot. When I start my car it revs at about 2k-3k rpm. It also does it when I come to a stop. When I come to a stop it will stay at a higher rpm than that of idle speed. It drives ok when on freeway but uses more petrol. I have changed the water & petrol pump but no luck

yes it could be a bad ground. I also would make sure that all connections are tight as well
