I have a Buick Leabre that is bucking at times intermittantly while hot . It causes check engine light to come on and vehicle to losse power, once problem goes away, vehicle runs normal. No codes are in system. Replaced ignition coil about a year ago as well as ignition module and cam/crank sensors for a like issue that turned out to be the MAF sensor. Looking for other hints.
