It cost me $100 to have my computer reprogrammed. That fixed it. Still, it only took a few minutes for someone who knew what he was doing and saved me a day of changing a fuel filter and going all over the car checking a whole bunch of stuff before I took it to a mechanic.
There are many reasons as to why a car may lose power while driving. However, the most likely cause is a bad fuel pump. This causes the car to 'think' that there is not any gas, so it begins to stall, and eventually stalls while driving.
Car needs service
Gravity! We fight that loss of power by using more torque.
might be a dirty fuel filter
Hmm... while driving, and/or intermittently? Or has something really gone south and the car just has no guts ever? Can you be a little more precise? FriPilot
i replace the erg,tps,idle control module and ignition control module,and while driving past 30mph i loss power why
Texting, drinking, smoking, eating, singing, applying make-up, juggling, etc.
Bad connection somewhere? Loss of power? (check and wiggle fuse)
Perhaps alternator is not charging the battery properly Test with a voltmeter - fully charged battery should read approx. 12.8 without engine running With engine running should read 13.8-14.2
If it is more of a noise than a power loss, then you may simply have a loose exhaust bracket or heat shield. Either of these can make a lot of noise under load. If you are experiencing a loss of power, then the problem may be that the catalytic converter is beginning to fail. If so, replace the them soon.
A bad throttle sensor can cause several problems. Symptoms include rough idle, loss of power, and even power surges while driving. .
Gears slipping, such as sudden high RPM's and loss of power while driving. Failing to change gears at a certain RPM in an automatic.
