Guys, the 96 bonneville is still stalling on me.
New parts mass air flow sensor, plugs wires harmonic balancer, and crank position sensor.
I dont even want to go into how much money.
Car still stalling after a warm start up. car will do cold start fine, or if it has sat over 2 hrs it will start fine.
but a restart after 10min of sitting, up to 2 hrs.. and the car will not run.
Any more ideas? no check engine light
:Welcome


Moved to 92-99 section -Toddster.

Is your check engine light on and if so have the codes been pulled?

NO check engine light at all!

Sorry I see I missed that at the end of your post. There are some codes that will not throw a check engine light so it may be worthwhile to get a scantool on it if you can.

I actually requested that at inspection 1 week ago, and was told no codes showing as pending.. Im a pretty educated/mec. inclined person, but Im stumped.. cause its a constant intermitten problem.. if that makes sence... I have had it at 3 mechanics now and no answers!! I finally assumed it was the crank position sensor from all the info I had, and since the harmonic balancer had to come off anyway, I replaced it as I knew they go bad anyway..
Any other ideas?? the car always starts.. just stalls when the car is warm from driving and has sat off for 10 min up to 2 hrs. after the 2hrs.. its fine.. if its only sat for 5 min its fin..
IDK

May sound odd, but check the ECT sensor, that'* Engine coolant temp. Also check intake air temp, and the idle air control. These couudl cause the problems your having.

thanks I will check that

check for corrision under the ignition module. had that happen on my 93 buick did the samething cleaned it up had good contact again and worked fine . worth checking out

thanks, I will have it checked!
