My Kia runs great but when I slow down in town driving sometimes it will just cut off. It will restart fine.


I would have a Fuel Pressure Test done, to ensure the Fuel Pump is working properly. A bad fuel pump will not throw engine codes.

98 and 99 intrepid was manufactured with weak fuel pumps causing them to vapor lock try pouring cool water on the fuel rails on the intake to calm vapored gas then try to start it. Even the temp gauge at half way mark is probably still low on coolant causing engine to be warmer than normal causing the vapor lock to fix this problem replace the fuel pump with a 2000 or newer intrepid fuel pump that carries a little higher psi to prevent vapor lock from reoccurring this pump is compatible with your 98 it will plug right in

Bad fuel pump diagnosis? small flutter in engine got worse within 20 min of driving and had to stop


If the engine wants to stall as you accelerate,and sometimes cuts out at highway speeds,...Its the fuel pump,If it misses at idle,and while driving,its the fuel filter,Have the fuel presure checked,or change the fuel filter,when you change the fuel pump,also ghange the fuel filter.
