Ok odd problem here. Yesterday while i was merging into traffic i had to floor the van(idiot driver) and then slam on the brakes for a red light, problem was as i am coming to a stop the van starts running terriable. SES light comes on, its barely running i tap the gas it dies. Put it in park and it wont start back for about two or three tries< then it fires up but is idling REALLY high, like i had the pedal pushed down a little. Its running fine besides the high idle, the ses lights off and when i drive away it runs fine.
Stopped and bought some fuel injector cleaner just in case and drove it another 25 miles and it ran great. Today on the way home when i pull to a light it starts misfiring but not even close to a bad as previous day. Any ideas on whats the problem? Oh btw van has new plugs, wires, cap, rotor, coil <all ac delco, and a new wix fuel filter. The fuel pump also delphi has about 24k on it and is roughly 1.5 yrs old
