About one month ago I had a problem with some stuttering on acceleration a couple of minutes after starting the car. After that period of stuttering it runs great with no loss of acceleration. It happens consistently each time I drive. I replaced distributor cap, rotor, wires, plugs and air filter and checked the timing(normal) with no change. I finally replaced the fuel filter and the problem seemed solved.
Unfortunately, last week it started the same behavior again. The fuel pressure is normal during operation and with the fuel pressure regulator vacuum hose disconnected. The only thing I noticed is that the fuel pressure drops after I stop the engine. Within about 5 minutes it is down to almost zero. Could this be causing these symptoms? I imagine fuel pump replacement is the solution. What do you think? Thanks.
have the same problem?
