I have a 1994 Honda Accord Ex with a vtec engine. The car takes awhile to stop when I havent be ran for a few hours. It also shuts down at 3500 rpm. The car runs fine once it start as long as you shift it by 3000 rpm. I have changed the fuel pump and the distributor. I was told that more than likely is in the ECM but I was tryna get a second opinion before I go buy one.

Hi Lilsteve21,

Thank you for the donation.

Is the Check Engine Light showing?

Do you mean to say the engine would not go over 3500 rpm?

You mentioned it takes a while for it to stop, do you mean to say after ignition switch is turned off the engine keeps running, commonly known as dieseling?

There are a few possible causes for this problem and ECM is one of it.
Others are
1. Faulty Throttle Position Sensor
2. Clogged catalytic converter.

Hi Lilsteve21,

Difficult starting could be due to
1. Weak sparks. Test if the sparks are bright blue by attaching a spark plug to one of the wires and grounding it to the engine while cranking. An orange spark means the ignition coil weak.
2. Low compression. Did you do any repairs prior to this happening? Eg, replacement of timing belts, distributor, throttle body?
3. Low fuel pressure. Could be a faulty fuel pressure regulator, weak fuel pump or clogged fuel filter.
