Question about 2001 Oldsmobile Silhouette

1 Answer

Low idle and dies when hot

No codes or trouble lights. 209,000 miles with a pressure regulator,fuel pump, and thermostat at about 200,000 miles. The engine was hot and it will drop below 500rpm and die. Start with throtle pressed slightly. Then dies if released. Same when coming to a stop sign.
Thanks

Check and clean your idle air control port. If you pull off the air intake port and feel inside the throttle bore you will feel a hole in one side or the top. Clean that out real well with a brake cleaner or carb cleaner solvent. You may also want to clean out the the throttle bore itself. That should at least help with your idle problem.

Good Luck

have your fuel supply checked

Mazda3,2005 trouble code p2177 system too lean off idle bank1


Check for correct fuel pressure.
If fuel pressure is low could be bad fuel filter, fuel regulator or pump.
If fuel pressure is correct could be bad MAF sensor, injectors, O2 sensor or vacuum leak on inlet manifold.

1989 Cutlass Ciera 3.3l Stalls, will not idle


if dies immediately when u put it in drive then whats happening is the torque convertor on transmission is lock and need to unplug the electric connector on the transmission cause that's all it controls, if dies in park u most likely its Idle air control valve on your throttle body, if it does it when fully warm ur injectors cause that .... just try to clean idle air control valve first and unplug transmission connector first u should be running better

Motor shuts off when started up,shuts off when driving.


hot engine or cold, or both? 180F+ is hot.
Shuts off, idling or on the fly, say at 30mph right foot down it dies?
just clue here...
engine stalls. is complex. but in the macro its below, using tools finds the reason,, but you never said did it restart easy./??????
1: lost of engine compression hot engine, (or overheated)
2: lost 12vdc electric power at stall (caused it) dash goes dead. ?
3: lost spark, test spark at the failure point. if dead trouble shoot speak.
4 bad fueling, too lean (say the fuel pump dies) or too rich.
too rich causes wet spark plug tips. (lots of causes )
5: stalls due to idle RPM too low, below 800 is too low.
too low idle rpm is caused by many things, but top 2 are.
A: EGR stuck wide open, clean it, as the books shows at 60k miles
B: ISC stuck closed. (same deal clean it)

now repost and say when it stalled,
at a read light or flying up a hill wot, wot= wide open throttle.
and when it dies, is the restart easy or hard.

The low oil pressure reads out on dash sometimes when coming to idle but goes back up right away sometimes on own or just by tapping gas. the pressure gage is always very steady at about 40 psi.could this...


I only use Mobil 1 Full Synthetic in all vehicles

With 209,000 miles, your going to get those type
issues,because the engine has a certain amount
of built up sludge ,if you want to call it that.

Oil flow will be hindered here and there.

The oil pump-maybe
The sending unit-check it out or replace

Put a mechanical gauge on the engine
and drive it, to at least see what that tells you.

Don't put any additives in the motor.
Stay out of the auto parts store Isle,they
aren't necessary.

I would start testing the alternator and electrical
system firstm as you say at an idle,then goes away

Also go over the entire engine,because it sounds as though
the idle is a little low

I have 8000 miles on my Tucson check engine light came on at start up this morning...gas cap is tight...no problems?????


there are over 200 reasons for the check engine light to come on, the gas tank cap is just one of them, this light and the problem that turned it on are most likely covered under the federal emission warranty, contact the dealer. see trouble code list below for some of the probelems that cause a check enghine light.
