When I first drive my car after its sitting overnight, when i hit the gas, there will be a bit of lag, and then the car will go. Afterwards I drive for a few mins, and its perfectly fine. It just happens when the car has been sitting. I think the fuel pump maybe going out? Any Opinions Ive already done a full tuneup minus PCV. Thanks
Mine used to do that. I cleaned the MAF and the IAC valve, also replaced the TPS sensor and adjusted it to .99 volts. It doesn't do it anymore, or yet..LOL Vic
