At first i thought the car just didn't like the cold and needed warmed up but when I took it on a 2 hour trip and it cut out the entire time I realized it wasnt the issue. I have came to the conclusion if I let the car sit until the check engine light pops up it will not cut out ever. So its not a motor being cold issue. It makes no sense to me. Every single time I go to drive I have to wait for the check engine light to show up or longer for me to put it in gear. If I put it in gear or just move the car down the driveway before letting it sit it will cut out the entire drive. Any ideas of what is going on here? INFO: Car is cammed, bored, new distributor, coil, plugs, and plug wires. Smog pump deleted Ac deleted EGR deleted. 5.0 - 5 speed

First thing to do is to dump all the codes, that will help to narrow the issue down and we can help more from there.

There are so many things to talk about here, first question is did you do the work to the car?
If the computer is not giving up codes either the computer is bad or important grounds have been left out.
Are you using the test plug under the hood by the passenger shock tower?

Help me create the "Surging Idle Checklist"

Updated 05 July 2022 to add rough idle when cold and smooth idle when up to normal operating temperature. See the EGR tech information, section #15 for more help. Many of you are familiar with the "Cranks OK, but No Start Checklist for Fuel Injected Mustangs" checklist and the No Crank...
