Question about 1995 Oldsmobile Cutlass Supreme

1 Answer

Car drives under power but stalls at stop light. Injectors replaced but did not fix problem. It has 140,000 miles on the 3.8 24 valve V6 engine.

Engine idles rough and has to be throttled to keep it from stalling. Once the car is going it runs great. Injectors have been replaced but did not solve the problem.

Your idle air control valve has gone bad.  It is located on the throttle body and is normally held in with just a couple of screws.  The IAC does just as the name says and controls your idle.  You can pick a new one up from AutoZone for around $50.  Good luck and let me know if you have any other questions.  Please rate my response and thanks for using FixYa!

My truck is a 1994 v6 nissan vg30e series overhead cam if its a valve burnt wouldn't it get worse very quickly? Or can it be a injector problem


try posting the symptoms. hot and cold engine.
idleing, racing idle, driving, flat or hills.
misfiring, flooding, stalling,, bogging, low engine power all the time.
there are many symptoms not just those, even noise.

if compression is good, the valves are ok.
and if serviced right. ever do a 60,000 mile tune up>?

I have same problem, I have 96 Camaro V6. Engine will miss at idle while stopped at light and seem ready to stall but won't stall. Also while driving engine will miss and seems transmission is slipping. My problems in these areas getting worse. Car has 44,000 miles. For what I paid for this car new ($16,000) I must say it has had many problems.

it's the EGR valve and can be fixed by anyone. It involves disconnecting the battery, remove electrical connection, and removing 2 screws and cleaning the surface area well and replacing it as well as the gasket. A new EGR valve runs around $120 and trust me you can fix this and save hundreds!

2001 LINCOLN LS V6 - ROUGH IDLE / SOMETIMES STALLING.


Very common problem is about a dime size hole wearing in the rubber elbow on the PCV valve located on the driver side rear of the intake manifold.

Car stalls


Here is the most common cause of surges and stalls and low idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Car quit and wont restart


It could be a any or a combination of failing components. If you haven't changed the fule filter recently (say within the past 20,000 miles) I'd change it first. Next. check the fuel pressure at the service port near the injectors to ensure you're getting the right fuel pressure to the injectors.

Stalling


Sounds like a fuel problem. Replace your fuel filter and add Techroline (Chevron product) fuel injector cleaner to clean your injectors.
