1966 galaxie weird problem
Hello all! Lately my daily driver has been acting up. It is a 1966 Ford Galaxie 500, with a 390 and c6 automatic transmission.
For those who dont want to read:
-sometimes engine idle goes way down when slowing to a stop (400rpm)
-at highway speeds, car seems like its randomly slowing itself down (almost like its engine breaking or something)
-get off freeway and idle will drop way down (like its stuck in 3rd)
-hard to start when it dies due to low idle
Just yesterday I drove the galaxie to the store with absolutely no problems. On my way back, the motor would idle way down as I came to a stop (around 400rpm, almost like it is stuck in 3rd gear). And when i gave it gas to accelerate, it would kind of accelerate for a second, then would like kick into gear and go. The next time I came to a light, the car just died in the middle of a busy street. Took me a good 5 minutes of on and off cranking to get it started again. Pulled into a lot and let it sit for 15 min. After 15 min, it drove the rest of the way like a new car. This problem only occurs sometimes, but lately seems to happen more often.
At highway speeds after about an hour or so of driving on the highway, the car will randomly start to slow down, almost like its engine breaking except the rpms stay pretty constant. This "slow down" will last anywhere from half a second to 10 seconds. Sometimes if I let off the gas slowly then re-apply the gas pedal, the car will kind of engage back into drive again and I can catch up to speed.
Hopefully I gave you guys enough information, and sorry for the long post. Just trying to figure this out so that I can drive my car again. Thank you!
