runnin rich and a heater issue
So i have a couple things i need help with... first is the car is runin rich, really rich its getting worse gas miledge then my 02 liberty, i jus bought the car and the guy said that he had changed the o2 sensor within the last year so i dont think it is that, i dont have a lotta extra cash so iam trying to pinpoint the most likely cause. the car has an intake, megan header, and 2 1/2" exhaust to the muffler, no cat. also the heater only blows hot air when iam stoped or driving slowly as soon as i go on the highway theres no hot air, any help is muchly appreciated

yea its the cheapest to fix, i was also told it could be the egr or the MAP sensor, fuel pressure regulator, or the fuel filter? how likely is it the fpr would go? the car does have 310XXX kms
