When coming to a stop or slow down as I take my foot off the gas the engine dies when I restart it I have to have one foot on the brake the other on the gas or it will die again. When I amgoing at higher speeds and let off the gas it doesn't die only when I am slowing down or restart it. Have already replaced the idle air motor, throttle position sensor what else could be causing my problem?

More than likely you have a restriction in the PCV system or idle control system.

However, we should start with checking for vacuum leaks just to be sure we don't have any.

Below you will find the testing that we need to run through in order to find out where the issue is.

As you will see at the beginning of this testing this issue could cause idle issues and should be checked if all else does not solve the issue.

Please run through this and let us know what you find. Thanks
