The issue:
I had the engine running great, drove the car for a few days until one day it overheated idling.
It did not boil over, it just started to lose power and died.
Now it's a hard(er) start, and once it warms up (not hot, just warm), it loses more and more power until it dies. Did I kill my heads? Overheat the C4 tranny?
Odd: idle in park has always had to be ~1500 RPM to idle at ~900 in drive
Help troubleshooting please. I've never had a carbd engine, or an automatic tranny, or an engine overheat. Obviously I can change stuff to prevent it overheating in the future, I don't know why it's dying though.
A little background:
Bought a 78 mustang with a rebuilt engine not yet all the way broken in, block out of a 79 5.0L, cams and timing are correct for regular 302 (not HO)
Automatic transmission, stock C4 from the 78. Sometimes I need to put it in 2 before it will engage.
Ran rough no power backfiring all the way home (it was cheap, I knew what I was getting into)
Got it aligned, the shop took a quick peek at the engine, checked compression, and recommended running the valves.
What I have done so far:
Pulled the leaking heater core and replaced it with a short length of hose. (before any of this)
Fixed the choke wiring
Loosened the rockers and re-torqued to 20 ft-lbs spec (proper process, pushrods down, etc.)
This got it running great!
However, idle seem weird, it needs to be quite high to maintain 900 in drive. I've never had an automatic vehicle before, don't know if this is normal for a C4.
