KA24E timing problem????

[Ricks15]

So I arive at work in the morning and slip it in to neutral to park and then I notice that once I park and had the car still on the RPM'S in Neutral would jump up to 1,010rpm then go down to 500rpm, It keept doing that for a while intill I shut the engine off.

can you retype that to make it more understandable?

When I put the car in Neutral the Revs go up to 1010rpm's when they are supposted to stay a 500rpm. When this happend the Engine check light went on so I guess there is a problem with the timing or something.

Your guess is most likely wrong, learn how to use the ECM and find what code it is throwing. Your car should idle up and then return to the preset idle speed after placing the car in neutral (sounds to me like you have an automatic).
