2001 Silhouette Shudders
Misfiring at idle and driving, especially under load, but can occur at any time.
On hwy, van will hesitate /shudder / jerk; letting up on pedal and gently easing back onto it will correct the
problem for a bit. Also stepping on pedal and shifting to lower gear seems to minimize at least feeling the
shuddering. Especially noticeable cruise is on. Cruise and A/C on seem to make it worse. Within the last day
have noted this: high idle, between 900-1100 rpm.
Where Are The Transmission Speed Senors Located
I have replace almost all sensor and need a diagram of the transmission speed sensors and shift solenoids.
The location of the sensor depends on which ones you want to change.
There are a few shift solenoids and an input and output speed sensor. I will send a diagram in a moment.
Referencing the diagram I will send, the solenoids in the side cover require lowering the
frame/engine/transmission assembly nearly out of the car.

Oldsmobile 88 Dies Won't Start
Live Chat:
Yes, i have a 1998 Oldsmobile Delta 88 3800. Car was driving fine. All of a sudden stopped. Tried to crank it
but, won't start. Its turning over very good but will not start. Changed fuel pump. Can you confirm you have
fuel pressure?
Yes, I pushed the button on the rail and fuel came out. Checked for sparks at the spark plugs it was good.
Didn't check all the plugs.
Did the fuel spray hard or just sort of come out? Just because there is fuel there, does not mean the PSI is
high enough.

Check Engine Light Code P1635 Volt Reference Problem
Replaced IAC and idle no longer raced but still was too high. MAF code for  reference voltage. Back probed
sensor and found 4.2 V at the MAF. Disconnected MAF  and reference pin was at 5V. Replaced MAF, code
cleared. Idle still erratic. Code set  for Reference A voltage high. Back probed TP, Fuel Tank Pressure
Sensor, MAP, and  EGR and found 5V reference either connected or disconnected. Noticed that upon key  
on, Reference A will go to 6.2V. Took fuel pump out of the circuit and Reference A  stays at 5V with key on.
Jumping in the fuel pump causes the Reference A voltage to go to 6.2V with or without the sensors
connected. All grounds have been checked good   and tight. Any ideas of what next? I can't imagine a
voltage regulator in the PCM failing in such a way to cause this behavior, but I'm at a loss as to what's
causing it. Maybe a back EMF on the ground from the fuel pump? In any case, any help/insight would be  
greatly appreciated.

1995 Olds Aurora 4.0 Oveheats
GM dealer replaced water pump, later replaced by-pass hoses beyond pump.
Question: Engine was losing water and noticed leaks. Repairs were done and re-done. After repairs engine
temp was way to hot. Bottom radiator hose burst. Replaced hose, still running hot. Replaced thermostat, still
running hot. Could not get to a repair shop, running hot, mechanic said to bleed air from block. Where and
how? Tried threaded cap where radiator flush goes. I don't think this is right.
1996 Oldsmobile Aurora coolant fan circuit
Numerous electrical issues, engine harness at firewall- replaced entire harness, corrected most other
issues. work  Checked fuses, No 2 and no 3 cooling fan relays.
With ohm meter checked control circuit wire for these 2 relays back to the pcm. Checked engine operating
temperature according to pcm via obd scan port, above perceived fan cut in. Appears pcm is not signaling
relays. According to wiring diagrams pcm should ground the control circuit in relay at cut-in and is not doing
so. Wire back to pcm is inactive according to ohm meter. Can not locate #1 cooling fan relay
(other 2 under hood at rt front) to perform same checks on it.

2000 Oldsmobile Intrigue DTC p0137 oxygen sensor
Check engine light codes P0137. Crank sensor replaced approx 20,000 mile previously.
Question: Code reader gives P0137, what do I check next?
I have been warned not to jump to replace 02 sensor because it could be something else. I have the normal
set of tools such and a DVM.
Answer:
This code is for low voltage on 02 sensor #2, post catalytic converter. Several things can cause this condition.
Oldsmobile Alero misfire no power
The vehicle was just in a front corner collision. Changed spark plugs.
Question: I just had a collision in the front driver side corner of my vehicle, everything is pretty much
cosmetic, but after the collision the car started idling funny, and lacks power when i push the gas
and is really hard to start in the mornings.
Went to Autozone and the guy said it was a mis fire code, and to change my spark plugs and it
would fix it, i did, and it did nothing. Is there a sensor or something that could make the car act this
way? That could have possibly been messed up in the wreck, thank you so much.

I have an Oldsmobile Aurora 3.5L and it has had the light on for fluid level low , and has been worked on for

the other way around. Then my car acted like it wouldnt start , but it did and i was driving. I got home and had

Replaced radiator, thermostat, water pump, reservoir cap, and flushed system. Ever since i
replaced everything above the car still overheats. When the car is running hot the coolant runs out
of the reservoir tank. At times when hot cold air blows out of the vents before turning hot. If been
told that it is possibly a bad gauge or bad head. Please help.

Check Engine Light And Runs Rough
Replaced Intake Manifold Gasket replaced a few weeks ago.
Question: Check engine light came on and car began to run rough after I had the intake manifold replaced on it. Was
told by another mechanic that vacuum hoses were broken and one needed repaired. My question is, could this be
from the intake manifold gasket being installed wrong?
It is possible that the job was done incorrectly. To replace the intake manifold gaskets, basically the entire top of the
engine has to come off. I have also seen the incorrect gaskets installed. This causes several different problems. That
job includes removal of many vacuum lines and hoses. It is very possible the mechanic broke one or more, especially
it the car has a lot of miles on it. The hoses and lines would be quite brittle and break easily.
