I have a 90 integra with a 98 ls b18b in it my fuel pressure holds steady and then out of no where the fuel pressure gage surges and then slowly drops then car turns off I turn the key off and back on and it goes back to proper pressure. Change the fuel pump fuel relay fuel filter next thing I can think is bad gas would that cause that
