flassed less engine power wth?????????
Flashed reduced engine power ! Electronic throttle control problem ! Your best bet ,take it to a GM dealer , buick , cadillac , GMC . You do not have diagnostic test equipment or knowledge to even diagnose this.
It is probably one of three things. It isn't getting a proper spark, proper fuel, or proper compression. Good luck!-------------------------------------------------------------------------- VAS 5054A
Sounds like your alternater, get a multimeter set it to volts start the car then check the battery is getting 14 or over volts from the alternater to the battery , if your getting less than that it's not putting enough volts back to the battery to run the car with good luck colin
There are multiple reasons. Need to start the process of elimination. First things first, the cheapest thing to check is the battery. I've had several vehicles which displayed the same thing: ran one day, wouldn't start the next. Fortunately, they just needed a battery.
After that, could be other issues: alternator, starter, possible timing component issues, fuel pump.
I know this is vague, but, the it is sort of a loaded question.
have diagnostic codes checked to see if you have a cam or crank sensor fault. make sure fuel pressure is at the required pressure, just testing to see if you have fuel at the valve is not enough. replace all spark plug wires. if you replaced two then all are just as old and even when they "look good" does not qualify as "they are good". Replace coil pack. start up drive away happy
That fixed it. Thanks. I appreciate your help.
