,
I have a 2004 Buick LeSabre Custom that has 43,000 miles & is in excellent shape but the engine is skipping & shutting off at stop lights. It will run great then skip & shut off every few miles, it just starting doing this. No lights on the dash. any suggestions

 

It was the MAF sensor, purchased one on Amazon for $28.00
The screws were a tamper head so I replaces them with Phillips head from Home Depot & a drop of lock tite.

 

Thanks for the update.
