#45 of 138 1997 Buick LeSabre Oil Pressure
Sep 29, 2009 (6:11 pm)
I have a 1997 Buick LeSabre (3.8L) with 187K miles. I've changed the oil & oil filter religiously every 4-5K miles. I recently had an oil leak fixed. The oil sending unit was the culprit and was replaced. So no more oil leak. However, now I see a symptom I've never seem before. The oil pressure will fall nearly into the red at idle after car has been driven for awhile and is nice and warm. Was wondering if this condition points to the recently replaced oil sending unit or could it be the oil pump on its way out? I am going to change the oil and oil filter again (I did it just before I had the leak fixed). I thought maybe something clogged up the oil filter. Any other ideas and/or suggestions. Thanks.

Ok my in take gasket warped and water ended up on my spark plugs. The car stalled out and shut down. Oh check engine light came on before the car died.
The water was drained from the engine and new plugs were put in as well as wires. It was hard to start the car and it tried to shut off on me as it sputters and shutters.
New the problems. I though was cared for after the vac line was changed, plugs and wires rechecked and a gas line cleaning as well as a TPS censor.
Now the car does not want to take hills, it surges when I put on breaks, the car pulls funny at 50 to 53 miles an hour and it shutters a nod sputters still as if it wants to cut off on me and finally the engine made a strange revving up noise when I went to shut it off after driving 20 miles to work

What caused your intake gasket problem? Are you meaning a head gasket leaked? That usually comes from overheating the car.
Are you saying the upper intake manifold gasket leaked? You need to tell us what year car and how many miles are on it and what has been done in the way of repairs in the past.
If water got into the cylinders, then it will do that again. The coolant will hurt the bearings in the motor so driving it without fixing it is asking for an early trip the junkyard with a blown or ruined motor.

The intake gasket had warped and water was on spark plugs.The car did not over heat the gasket, filter and intake. I can not describe it anymore because the autoshop did not provide me with any more information than what I gave you. After this was taken care of the car cranks and runns but it does not like to take hills and it shutters and sputters from time to time like it wants to stall out. It pulls hard when the car get to 51 to 53 miles per hour. and some times it rvveis up really hard befor it hits 30 miles per hour.
I hade thing ran for codes and I got a po102 MAf or VAf check low air intake. PO121 Throttle Pedal
and a PO122

Hi, If you ignore the intake manifold replacement, you are doomed...the plastic unit that comes from the factory has a flaw...which is corrected by replacement after market part (yes I would look for that at Autozone...if there is one nearby, I did that for my current car ( the part is about $128) There is 2 scenerios here, #1, is really death to the engine, as it will (at highway speed) attempt to compress water that it sucks into the intake, (and liquids cannot be compressed) and in second the engine will self destruct...like explde..(not like an explosion) but,you can kiss the engine goodbye...#2 is less problematic, but not your situation, it results in so much oil under the intake that it causes loss of oil (unidentified)..it can be observerd when the intake is removed..(a whole lot of oil on the underneath of the plenum) which is the part that you are replacing., and in that instance there will be alittle smoke when you start your car.So in the end you need either to be competant enough to perform this removal, or to find a certified tech to do the job, (if that person knows how to perform this it really takes about 2-3 hours) In reality, if unknowlegable 2-3 Days...really due to all of the nuts and bolt involved depending on all of the really necessary and unecessary bolts that either do or not need to be removed...I guess that you get the idea???? Other than that if the vehicle has had good care and it is otherwise in good condition...go for it...Hope this HELPS

The intake gasket, and filter were changed whether the person had a clue as to what they were doing is beyond me. How do I check to see if the job was completed correctly?

Ok I have my bill this is what each shop did.
Shop one:Replaced Intake, gasket, filter, and thermostat
The car still ran bad it acted like it wanted to stall. It sputtered and spat and shuttered
So I went to a second shop.
Shop 2 replaced: TPS, plugs and wires, cleaned fuel injection system, RR Vac line and oil change.
The Check engine light came on about 30min after I left the shop. The car does not like to take hills and it pulls when I get up too about 51 to 53 miles an hour.
Is there a dummy check I can do, to catch something that might be simple?

#54 of 138 1993 Sputtering LeSabre
Oct 01, 2009 (6:23 pm)
Hey guys I have a 1993 Buick LeSabre with 153K on the motor and tranny. When I bought the car it had sat for a year. When I got the car it started right up after I bought a new battery for it. But now 17K miles later it sputters when it comes to a stop. The check engine light does not come on. But as I am driving down the road it runs like a scared cat. It has great pick up and acceleration. But what is causing the sputtering when I come to a stop? Does it need a tune up? Or is it a vacuum leak? I am getting over 30 mpg on the highway. I have come to the end of my guessing of whats wrong with it. But help me guys.
