PLEASE HELP! HYUNDAI EXCEL STALLING
 

Hello
can anyone help me..I have an old 1992 Hyundai excel 1992 1.5 liter , fuel injected, standard..I replaced cap, rotor, plugs, but when I start the car, it runs for a few minutes, then stalls..I notice some rusty water coming from the tail pipe when running, and added fuel injector cleaner..still have the same problem..it cranks, runs, then stalls..any ideas??I also changed out the fuel pump relay..its not that! PREVIOUS to this problem, the car ran well, but when i shut it off and would go to RESTART IT (WHEN STILL HOT), THE IDLE would rev really high. I am trying to get readings off my multimeter..is there any other way to read these codes..looks like a 15 and 21(idle motor sensor). Do help w/ any info you may have..THANKS!

Hey gail, i'm new to the forum so i just read your post. Since your car has some age on it and your seeing rusty waterexit the exhaust, you may want to check and change your catalytic converter. I had an older car and this was the same problem for me. It had pretty much rusted shut, it is possible. If the exhaust system does not flow properly you could be sufficating the engine.
