smokedout240

okay so I just bought the 240 a month ago and it was okay... The car wouldn't heat up so I replaced the thermostat... Now it has trouble starting... The first start of the day it starts fine but If I drive it a Lil while then shut it off it has serious trouble starting... I hve to crank it for like 30 seconds and tap the gas... After it cranks over it wants to die so I give it more gas and it struggles to bring the rpms up... After it gets like 2500 rpms it will stay running but it will continue to hesitate under 2500 rpms... I have changed plugs twice changed cap and rotor... I bought the car with aftermarket fuel pump, header, intake and exhaust. The car has no o2 sensor and is missing part of the egr(I'm not really sure what it is)
