1990 Buick LeSabre QuestionsRefine by vehicle
the car generally runs fantastic it just started this hesitation.when you are accelerating from a dead stop the car sputters as if it is on that ground by a toll. But if you roll just a bit first it goes just fine! after that it rides great.
I have a ’90 Buick LeSabre with the end of the shift knob broken off. I purchased a new shift knob but can’t for the life of me, figure out how to remove the damaged one and install the new one.
Can someone explain how I can do this?
Thanks in advance,
my 1988 Buick lesabre was overheating so I replaced the water pump.now it starts and shuts off after ten to twenty seconds .why could this be what are the possibilities??
I recently changed thermostat and the radiator and water pump seem to be working seem to be working fine.
((Note: The year and make selector at this site does not concur with my car.I have an 1989 ParkAvenue)) Seems to start and run smooth and even can accelerate to 3K+ rpm smooth and steady. When selection of any drive position and begin to accelerate, engine goes into a surging cycle and continues even when gear selector is back to Park; will not rev when in this surge cycle, bogs and almost stalls. I can turn off ignition and restart engine and is smooth running again. Again I can rev to 3k rpm smooth and rpm steady. Select gear and accel... repeats as above. Acceleration is at about 1100-1500 rpm to climb a hill when cycling surge begins. I can duplicate surging with brake on & in drive & accelerating; surging starts at about 1100-1200 RPM. Again, surging/cycling resets by turning off and restarting engine. Maintenance/shooting done recently: 1. Checked fuel rail pressure @41 psi; 2. Changed fuel filter; 3. New air filter; 4. swapped out the MAFS; 5. New Oxygen sensor; 6. Oil & filter changed about 200 miles. Where are the ECM, IAC, ICM located that I can do a vibration/tap test?
On the 3.8 lt. motor, does the front engine oil seal need to have the timing chain cover off, and to replace it from the inside?
one person said the problem is transmission mounts shops tell me it needs a complete internal rebuild does this 90 buick lesabre with the 3.8 motor have transmission mounts and what is their location
I have a oil leak around my front seal. My mechanic put a new seal in and its still leaking a lot at between 1100 to 1500 RPMS. He said the crankshaft is floating up and down at about .025. The car runs fine. Does this sound right? Help!Thanks!
My 3.8 motor has develop an oil leak on the front side of the motor and getting on a pulley which in turn is being thrown around. I recently had a timing chain replaced. Any idea where I might start looking. Its hard to see around all of the parts. Thanks!
I have changed the ecm, crank sensor, temp control, ignition coil, coil pack, thermostst, battery, cables, but the problem still persists also had the plugs and wires change there is no specific time it happens but after it stalls it usually starts back up but sometimes it takes a few minutes for it to restart i'm almost at my wits end but I won't give up cause I really like the car so I want to get it fixed it has been tested and retested for everything but it won't stall when it's at the mechanics HELP! !!
Car will start up with no problems, I will drive it around for a bit a shut it off. Will start up or will not start,when it doesn't start it will turn over but wont fire, or will start for a few seconds, but will sound like its misfiring or runs like hell and shuts off. If you let the car sit for half an hour to an hour it will fire up like nothing happened and the motor runs fine.
they seem to doing the job but at some point they need to be replaced or how do you check them to see if there time has come. 98,000 on the vehicle. thanks
The check engine light came on showing dtc65. I looked it up and it said "Right bank O2 sensor rich exhaust indicated" Have any what that means? Thanks.
