Lets start off with the.... The ole lady was drivin the burban yesterday and she parked it and it died. Now i know that everyone says do a major tune up. Well it has new Accel U groove plugs, 8mm wires. Jegs red hot coil, air induction kit. I have no idea other the poss. fuel filter. any other ideas? Next rough idle when u first start. smooths out after it warms up. Any ideas? Last i am in need of a "Y" pipe. they do not make a aftermarket one. Is this a dealer only item? Or should i just rebuild the collector end witch rotted off? Thanks for the help!!!!!!!!!!!!!
