Question about 2001 Chevrolet Impala

2 Answers

01-LS stops when idling/driving/hot/cold....

My 2001 Impala LS w/ aprox 122K miles recently began to stop when I'm driving it. No sputter or other warning - almost like switching the key off. It starts right back up after coming to a stop and putting it into Park. It has done it several times in the last week, however, not at the mechanic's where it spent today. I thought maybe bad gas and tried a gas additive, but that wasn't the solution. I can't go on like this.

Anyone got a clue? In my opinion it a fuel delivery problem (filter - pump?) and no, I don't know then the filter was last replaced.

Thanks in advance for your assistance folks

    No aftermarket items have been added and I'm the original owner. I'll add the ignition module & crank sensor to the 'things to check' list. Thank you.

Changing the fuel pump and fuel filter finally fixed a similar problem to this on my 199 Alero.

Make sure to check for and aftermarket ignition module installation in other words make sure the ignition module is factory and not aftermarket,
this is not a fuel problem because fuel problem acts diferent
but coul be your ignition module or your crank sensor

2003 Lincoln LS hot air while stopped cold while driving


Hello
Based on what you have said and my 30 years a Ford dealer tech I believe you have a slightly low AC system refrigerant charge due to a small leak at the AC compressor or the AC line connections. I would have a shop hook up a set of gauges to monitor the pressures at idle and see just how low it is. DO NOT ADD UNTIL YOU KNOW HOW MUCH IS NEEDED, YOU CAN LOCK UP THE COMPRESSOR.

Honda accord ex 2001 check engine light suddenly came on, car started to idle roughly


If it's running rough, chances are that it's misfiring. If the Check Engine light is flashing/blinking, it is definitely misfiring.
If that's the case, drive it as little as possible... Or straight to the mechanic because the more you drive it while it's misfiring, the higher the chance is of you ruining your catalytic converter.
