how to KEEP teener running in hot weather, cool and cold weather good for 74 teener - WHY Options

[9fourteen14]

I have stated my question in a way to get the most responses/help/ideas possible.

when the weather is warm to hot and I have driven it for 4 miles or so, It really
wants to die. and then if i drive it any longer it will die in the hot weather.

THEN

after just waiting until (it seems like cools off - because engine if not running
it will start right back up and go.) in the hot weather.

I know others have experienced something like this BUT
I have never seen any answers that come close to my situation.

thanks for your help.

I didn't necessarily think vapor lock was the prime suspect - but I was explaining what it is. Now that we know you have FI, it does sound like you're running way too rich. On D-Jet, that can be one or more things that include:

1. Fuel pressure set too high. Check fuel pressure to make sure it's ~29 psi.

2. Blown MPS. Test with vacuum pump.

3. Failing CHT or intermittently failing CHT circuit. This is my "favorite" as it's pretty common.

4. Stuck injector and/or stuck CSV. If you have new injectors, you can also just try disconnecting the CSV to see if that helps.

Here's a great resource for you:

That's got LOT of info on these components and how to troubleshoot. I read that page often. Start checking and eliminating variables and potential causes. If you do that methodically, you'll get there, and we'll help.
