Question about 1999 Oldsmobile Alero

1 Answer

Check engine light flashes and it dies while it's idling.

I have a '99 Alero. It has been making a noise for a while, but it hasn't effected the way that it drives. {It sounded like the engine wasn't firing on all cylinders.} Then on Monday, I was driving down the interstate and it started to sputter a little bit, the check engine light started flashing. I pulled off the road and it completely died. After a few minutes, it started back up and I made it home. Any time I had to stop for a red light, etc, and started to excel again, the RPM's would shoot up, but it wouldn't go past 10mph.
Any ideas? Thank you!

Why is my 99 Ford Ranger dying when I step on the pedal?


Is the check engine light on when the engine is running ?
You'll have to figure out if it is a fuel problem or electrical problem.
Have you checked fuel pressure yet ?

You don't have right AIR: GAS ratio of 14.6:1 at idle. If you don't have idle adjustment, you need to have throttle valve clean.
If it doesn't work, then your Fuel Distributor is drifting out of calibration.
Don't worry about check engine light comes on when the engine dies. It is designed that way.

My 99 Alero starts up then dies after 1 second. I


check air flow duct where the throttle valve is . check the pvc valve . make sure it isnt stuck open. check the egr valve . it will stick open stall out motor .use a scanner it will tell you if you got egr valve problems. check fuel pressure. it could be stop up fuel filter bad fuel pump fuel pump relay.your car problem sound like a major vacuum leak . change spark plug and wires if they have not been change in a while. it could idle air control. hook a scanner .it could give you a code.

I'm sure you have installed a fuel pressure gauge and monitored the fuel pressure while the problem is occurring?Another diagnostic tool which is easy to do,is while the problem is occurring,unplug one sensor at a time beginning with the Mass Air Flow first,.if it uses one.Many times,not always,depending on the sensor,if the sensor is taken out of the picture as far as what the PCM is seeing,like unplugging the MAF,the PCM will substitute the missing sensor output with a generic value that will allow the engine to at least run,and if unplugging for example the MAF,the engine idle speed returns to normal,you know you're onto the problem.You didn't mention if the engine ran ok other than the idle problem.As far as checking for vacuum leaks,i use something like brake cleaner or WD 40,more of a liquid,and it does sound like a vacuum leak.Plastic intake manifolds do develop nearly invisible cracks that open up more with heat.Revsisit the possibility.And as for the PCM,it is possible,but more likely a mechanical problem.Lastly,remove an O2 sensor or two before the catalytic convertor,run the engine and see if anything changes.Cheap way to verify the catalytic convertor is flowing and not restricting engine airflow,as i have seen bad cats cause misfire codes and strange problems.Good luck.
