Not that long ago the car was having some serious electrical gremlins, so I finally pinpointed it to the memory chip socket in the ECM having bad contacts... replaced the ECM, good to go. Other things replaced along the way were the wires, plugs, fuel filter, crank sensor and air filter. The car ran great after that, but recently it started acting up again. The symptoms are as follows:
Some time ago, the speedometer would go all the way to about 120mph when you would be sitting at a stop light. This happened for quite some time, but the car had no issues, so it was ignored. Now, as soon as that problem disappeared, the car has a lack of power and a stumble to it after it shifts into overdrive. Today, I barely got the car to start after some hard cranking and a lot of sputtering.... it'* about 0* outside right now.
I checked the coils... secondaries read as follows:
plug 1-4: 11.23
plug 2-5: 11.73
plug 3-6: 11.67
I checked the fuel pressure earlier... IIRC, the readings were about 30psi, and 35psi when I would goose the throttle.
Just searching for clues, as I'm working outside and it'* PAINFULLY cold here
Please drop some knowledge on me if you could!
