SOURCE: Mercury Topaz loses power while driving, and stalls out

Check fuel pressure. Sounds like a bad pump or plugged fuel filter.

Driving along lights dimmed, instrument panel died, loss of power then engine cut out & wouldn't start. Starts with a jump but when i turn key to heat glow plug, instrument panel goes mad


I assume there's a problem with alternator. Check the grounding to engine, check continuity of a positive wire between alternator and battery. the energizing voltage should be checked as well. Might be the bad connection between battery and vehicle body grounding. Diesel cars are sensitive even in a little loss of connection and rust in the connection points.

When driving my Audi A4 it seems to lose power and the ESP light comes on? What does this mean?


The ESP light refers to your car's traction control. The loss of power you feel is the car throttling back in an attempt to regain normal traction conditions. This is by design but if you car is flashing ESP under normal driving conditions, you most likely have an ESP sensor problem and should have it checked at the dealer.

I,LL BE DRIVEING DOWN THE AND IT WILL LOSE POWER


did you make sure its not the fuel pump. the mass air flow sensor would have set of the check engine light. try putting in a new map sensor never put a used map sensor in a car.

hope this helped.

Faulty Air Conditioning in a 2000 Nissan Pulsar N16


It's quite possible that your A/C compressor is locking up, thereby causing excessive load on the engine.(translates into lack of power to drive wheels) Typically there are signs, such as the noises you heard, or a slipping or thrown belt. If the compressor is locking up, being belt driven it will draw excess power from the engine. It's also possible that the compressor clutch in conjunction with compressor is going bad as well (both are usually related). That would cause excessive amperage to be drawn through the circuit, thereby blowing the fuse. Ultimately, it sounds like you have figured out your own problem, but I hope what I've posted helps.

Carburettor checkup and Tuning is necessary. Engine cuts in slow speed, so also check the accelerator wire.
