Bmw312i 2004. Lost forward power. Car went well until stopped on hill at lights would not go forward backed back to flat. Started very slow and then went ok

The only thing that comes to mind is the catalytic convertor in the exhaust system.It can become restricted,reducing flow in the exhaust system,which also reduces engine power.These convertors run at fairly hot temperatures,and the extreme heat and conditions aggravated,or overloaded it.It's not very expensive to have it checked at a reputable muffler shop.I have seen extreme instances where this caused parts of the exhaust system to turn red,glowing hot.

Hi and welcome to FixYa,

Offhand, definitely an electrical issue. Some ideas to check, consider and/or explore:

• IGN switch - check for loose, corroded or heating connections. To test, under normal usage of the vehicle, should feel warm but not overly hot. If so, then possibly loose connection;
• fuse/relay box - check for loose, corroded or burned terminals, holders, clips and connectors/pins. Use an electrical contact cleaner and spray. It may also be necessary to scrape to remove burnt marks/corrosion;
• fusible link - the battery would have 2 wires connected to the + terminal. The big wire goes to the starter, the smaller of the two is the electrical systems main wire. This normally goes to the fuse/relay box. Check for frayed ends, loose connection, corroded terminals. In some instances instead of being at the battery's + terminal, it is connected to the end of the big cable down at the starter motor.
• ALL connectors with big wires - these carry the main +12 either as always ON, ACC or IGN. If a connector has a wire bigger than the others, check them. It may be necessary to disconnect to enable you access to the inside pins/terminals. Scrape them clean.

need to recalibrate the throttlebody

You sould have recieved a "recall" notice in the mail about the cruise control for fire and failure issues. they are adding a fusable link where the cruise control harness connects to the brake master cylinder. if you have not had the recall performed yet you should SERIOUSLY consider getting it done, mainly so it doesnt catch fire, but "could" be the result of the failure you've been experiancing! btw, almost ALL Ford vehicles have been affected with the cruise control recall. hope this helps!
