Saturday night I took my car out for a cruise gave it some WOT pulls car was driving fine. I wake up on Sunday and the car would roll over but not keep a idle. One time I got the car to run at 2000 RPM, then idled for about a minute and then shut the car off and then it would roll over but not start again. There is fuel pressure, spark, MAF is clean and clocked correctly, put the computer back to stalk, flashed tune again, KAM reset, spark plugs are fine, no codes, battery is charged. I am at a lost why the car was working fine and this happened?
