91 318is Sputtering Problem
First Time User,
I have a mint 91 318is, I just replaced fuel pump and fuel pressure regulator in hope to fix a Hot Start Sputtering problem. Car starts and runs fine initially, however, sputters after the vehicle has been runned then turned off.
Example, first thing in the morning car works fine, parked at work till lunch time, car starts fine but will sputter when taking off, this only occurs when vehicle engine is hot. I was told that it may be a thermo sensor relay, is this possible. Any suggestions, Thanks
