ok guys, so last week i was on my way to circuit city getting onto rt 17 and i went to punch it to get on the highway and the car just died.. got the car started as i rolled toward the highway and then the car wouldnt rev up as i gave it gas.. the car died again as i was on the highway so i rolled over into a parking lot in which i couldnt get the car to start for a good 5-10 mins.. once i got the car started it wouldnt rev up past like 2,500rpms and was backfiring like a ****.. i decided i better get the car back home in fear of getting in an accident or stuck on rt 17..for the first few minutes the car would only go 35-40mph with the gas at WOT then as i got closer to my house decreased to about 15-20mph. car wouldnt start for a few hours later did the same thing..i let the car sit and didnt drive it untill 2 hours ago..

today my friend mike (maroman88 ) came by to scan the car to see if it threw any codes but it was no success.. started her up and it ran alright, so we took the car around the block and for the first half of my block the car felt ok as far as revving up and then it started acting up again.. top speed of 15-20mph and wouldnt rev past 2,500rpms.. got the car back to my house turned it off and now it wont start..anyone have a clue what this could be?
