I AM WORKING ON A 1999 LESABRE 3.8L. CUSTOMER COMPLAINS OF NOISE IN Left WHEEL
WHEN TURNING RIGHT. SOUNDS LIKE ROTOR HITTING THE BACKING PLATE. HAVE
CHECKED AND REPLACED EVERYTHING ON LF SIDE TO INCLUDE ROTOR PADS BEARING
AND AXLE. OBVIOUSLY I BENT THE BACKING PLATE BACK NONE OF THIS HELPED.
Have had strange tire noises, but make sounds turning either direction.
As long as you replaced the whole axle. Have had inner tripods make noise on that axle. Will ask
SF our trans guy on Monday. If anything with the transmission.
How about this, have had a few loose starter drive gears slide into the flywheel when making rt.
turns. In an open area, drive and keep wheel turned while it is doing the noise, then shut off
engine and see if noise stops (dont turn key all the way in case steering wheel locks).

Sometimes when I accelerated from a stop or just to get into traffic, the engine will
increase in RPM. The engine won't die completely, but will not accurate or
increase in power. The engine has eventually stalled & will restart. Let the engine
sit for at lest 5 minutes & the engine will restart & run like there is no problem.
This is an intermittent problem. Car will not stay broken long enough to be
diagnosed proper. There is never a check engine light & no codes are stored.
One time a cat converter code did set & the converter was replaced. This did not
solve the problem. The engine stalled the next day & died. It restarts a few minutes
later & I limped to the dealership. Nothing found & car ran well. The engine stalled
again 3 weeks later. Driving about 25 MPH, engine began died. 5 minutes later the
engine started up ran well.

Answer: This really did sound like a fuel pressure problem, but that is not the case.
You may have a crank position sensor acting up, or possibly a wiring problem
somewhere. Moving harnesses under the hood while running may cause it to act
up, or correct itself.
Grounds on the engine / trans bellhousing may be loose, or even a power feed
problem at the underhood fuse box. Either of these would most likely not set a
check engine light or codes.
Move those harnesses around, pull on the fuse box and harnesses, check the
ground, and see if this helps

Question: The odometer on this car is a digital display and it goes dark, or sometimes dim or other
times normal. How can the display be repaired?
First be sure that the odometer is the only display acting like this. If the backlighting of the radio and
HVAC controls etc. Or also doing dim or dark, then you most likely have a problem in the dimmer
switch. Try adjusting the switch when it is acting up to see if it changes any. If the odometer is the
only problem, then you have an internal problem in the instrument panel cluster itself. It would need
to be repaired or replaced. Best left to the dealer, since it would need to be programmed to the
vehicle after repair or replacement.
