Idle issue when hot

Not completely. It has a newer Motorcraft alternator. Oem
With heat and head lights on it will drop it
These are not answers that help, the volts will very according to RPMs normally, need to get familiar with diagnostic tools and terms, beg or borrow a volt/olm meter, read voltage at idle, nothing on, and then with blower, lights and wipers on, then say 1800 RPMs, and battery voltage with engine/key off. I have to write things down cause my memory bank is mostly full of useless crap that takes up too much space.
Also need to monitor fuel pressure to see if/what changes when it starts to act up.
We can point you in the right direction, a good start would be a repair manual or better yet an assembly/repair manual by Ford, ebay has some.
Some helpful info can be found in on the tech main page:
There is some info on the 3g alternator upgrade in there too.

Electrical Use a 94 engine with 89 GT wiring and A9L ECU in non-Ford chassis?

Perhaps, but it's not something that's even mentioned in the Monster swap manual (just re-read all the fuel related instructions) so I'm going to go with "close enough for my :poo:box" :cool: The FPR I have in the car was for a carb'd engine, so 6psi wasn't going to help me anyhow :) Worst case, I am over driving the injectors and running rich.. and I can add a FPR later. But shouldn't the A9L (with it's O2's) adjust fuel trim if it is seeing richness?

I'll toss it to the V8 guys on FB and see what they think (including Martin who wrote the book, literally). Thanks for the tip!
Only question I have is with regards “Low pressure adjustable FPR goes away, running stock Miata fuel pump for EFI motor”.

You do know that the Fird WCU is expecting 39 pig at the injectors and a stock Miata fuel pump delivers more than that.
wasn't thinking when I replied.. I'm using the factory SN95 FPR, so why would I have issues? It's a return style system (95 Miata chassis)

Unable to delete a post from 13 years ago. Please help!

I’m trying to delete one of the only post I ever made on this forum. It’s a for sale post for a car from 2011 and the post has my phone number and email address in it and it’s popping up on Google search. I would love to delete this, but cannot. Any help from admin please?
Can't you just edit your post and remove the info? Look at the bottom left side and click on edit. But the mods should be able to help to remove it.
What an awesome community!
