Check the IAC (idle air control) valve...disconnect electrical connector and remove it, usually two torque screws...clean it by spraying mass air flow cleaner on it including spring and pintle...spray it liberally..wipe straight down with a clean rag. Try not to turn the pintle..the pin inside the spring..if you do, it will auto adjust anyways, just take a bit longer...replace it and connect connector...go for a 10 minute drive...just saved yourself $200..take about 15 minutes...cheers
Good guess Christina351...
I was just in the process of writing a HUGE sympathy
note...
Assuming you have the 5 liter V8... (??)
your parts listings show you have a HYBRID system:
Rather than get trashed gain by the IAC/TPS answer
(ahead of me
(and lose another 20 minutes looking up PARTS))...
I'll simply say TPS (nah)...
You are having CHOKE ... IAC or Fuel Injector
seal issues... (depending on CARB options)

SOURCE: 1994 Buick Lesabre service engine soon light. Can't read code.
I found several shops in my area, Albany, NY that had the older code readers. It worked fine, and cost me $30.00. It showed a bad O2 sensor that I replaced myself. I suggest you go to a reliable shop. Auto Zone/Advance etc.. do not have the right code readers. Joe

If the trans.oil is dark brown in color and smell's burnt your tranny is probably on it's last leg.If tou have bad pump pressure or low oil you will have to rev the eng to get it to build enough pressure to move.Your detent cable or kick down cable is for passing,when you step on the gas when passing someone this cable is pulled causing the trans. to go into a lower gear and when you let off the gas it should shift back into a higher gear.if it's out of adjustment it will kickdown to soon or to late.If your car has alot of miles it may be in need of a filter and fluid change,but usually when slipping occures its to late and you will need a replacement tranny.Hope this was helpfull.

the transmission breaking apart but in a really slow way. There's not a thing that can be done to save it. It's going to someday give out. You can prolong it by not punching on the pedal to test it. just drive it normally and DON"T get the trans oil change. Just leave it alone... I own 89 P/Ave 156,000 original owner. Same thing happened to my car and picked up a used trans at junk yard and my mechanic installed it and runs like a baby at half the price(700.00). If you go to junk yards half of the park ave are because of trans. Good luck
