Cars running like Asssss.. HELP !
i have a 90 mustang, the list of mods are listed below. Yesterday i drove my car all day running around, car was running and starting up NO PROBLEM, lastnight i go out to my car to cruise around , and my car doesnt start! when i turned the key the motor would just keep turning , and turning , but never start up! i checked my plugs, wires ,ignition coil giving plenty of spark i didnt know what was goin on, i then decided to stuff the gas pedal to the floor while cranking the motor , and it started up !
This morning i had the same problem, i had to stuff it to get it start. But i notice the cars bogging at low RPM, but when i get to 3 grand it wakes up. but the bogging is feeling like it getting worse.
the plugs and wires are new, fuel filter is new, i have a 255 lph fuel pump.... i dont know.. PLEASE HELP ME !!
