Last week I parked the car in the garage, after running great.
Last night, started right up, wonderfully. Lowered the driver's side window. Turned on head lights. Then noticed battery light came on. Then noticed there was no power and I had to push the accelerator pedal 3/4 down to get it to back out of the garage (seems to be running on only a few cylinders, smelled lots of un-burnt fuel). Now, noticed none of the windows would go up or down, with headlights on or off. Barely pulled car back into garage. Turned car off, then all windows would go up and down. Noticed slight presure release after fuel cap opening. I am baffeled. What would cause this phenomenon and what can I do to resolve it? Any thoughts greatly appreciated.
