Hello my truck has recently started hard starting every time I go to start it. The exception to this is when I get gas right after I get gas will start fast no problem like before but before I really even get down to 3/4 tank it will do the same thing as before. It also has a rougher idle than normal and is more noticeable now. I've tried priming it two or three times no change. Newer distributor cap rotor plugs wires. In was half considering the Coil since its OEM 144k from 2002 But the gas thing is really throwing me off. Thanks for any help!!!
