Hi, i have a 92 coup de ville with 78,000 miles. Today while driving the car started sputter and could barely make it back,it wasn't overheating, just anyone have any idea.Thanks

 

Need just a little more info, Check for codes, fuel pressure, and use spark tester to check for proper spark.

C FAQ - codes

 

found some codes,E91,E98,E31,E52,EE,7.77 what do they mean. Thanks

 

E31 MAP Shorted
E52 ECM Reset
E91 PRNDL switch problem
E98 ISC High RPM P/N to Drive shift
How does car run now? Clear codes and post what comes back. Poor grounds are always something to check for, along with fuel pressure if you have access to gauge.
