My northstar hesitates at low speeds but runs fine after about 1500 rpm. It's not my head gasket, there is no water in my oil. could it be my fuel pump? or filter? my pump has been louder than usual at some times. it also has a spontaneous popping noise at low speeds. Help please. My northstar hesitates at low speeds but runs fine after about 1500 rpm.

You are likely having a problem with fuel deliver or air delivery. There could be a fuel pump, fuel filter, or vacuum leak issue. There could be other issues, but if the car runs ok above 35mph, it would indicate that at slower speeds, the reduced vacuum and fuel demands are casusing the engine to stall, whereas at higher speeds there is sufficient vacuum and/or fuel to keep the engine running. Sounds counter-intuitive, but sometime car problems are. You need to diagnose a few issues before you can fix the problem.
Does the car idle smoothly? How is the gas mileage (compared to when car ran normal)? Do you have sufficient power above 35mph? Has the car been worked on recently? What, if any, major issues have you had with the car?

CarGurusMay 25, 2014 - My car started sputtering when I was driving and just died. ... no- don'tkeep guessing- take it to a good mechanic in a good garage- "good" meaning, they won't be guessing- maybe you can fix it .... Used Cadillac DeVille".
I have a 1995 Cadillac Deville. The car runs great. When Its cold. As soon as it gets hot, if you turn it off it won't start. And when it does start is has no power and spits and sputters to the point where you have to lay on the gas to keep it running. My husband and I have done everything imaginable to this car and it will run great for a day or two then we are right back to square one. Do you have any idea what the problem could be? Please help/
I have this same problem, what is the solution
