Even at slow speed with cruise on and mainly at low speeds. I don't fool with cars like I used to and I haven't even looked at her car but my first thought was vapor lock or clogged injectors. Any thoughts would be helpful. Thanks Hammer Time Ultimate Carjunky / Moderator Jul 19, 2011, 4:19 PM Post #2 of 4 (3295 views) Re: 98 Buick Park Ave sputtering Sign In Vapor lock is not possible and these cars. I would start out by checking the computer for stored codes. You may also need to test your fuel pressure while driving to determine if it shows any changes during the failure. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

If there is replace the wire, plugs and affected coils. If engine light is one pull the codes and post them here.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
