1996 Buick Regal Q&A
1996 Buick Regal Question: Sometimes hesitates to start. Have to add RXP or other gas additive, then it starts.
I think you have bad gas or water in the tank. Replace the fuel filter, see if water or other contaminant pours out of the old filter. If that fixes it, drive it and see if it stays fixed. If it needs another filter, then you may have to clean out the tank. - Superbob
