I''ve got a 1986 Olds Cutless Supreme with the 3.8 liter V6. It has a habit of stalling when it''s cold generally but does it when warm as well. If ai start it in the morning, it''ll take a couple pumps to choke it and it''ll fire up easily. if i leave it for a min, ten mins, or even a half hour and go to put it in D or R, it''ll stall. On the highway when cold, if you put the pedal 3/4 down, it''ll bog out and die and when warm and you punch it already travelling highway speed, it drops a gear (which is of course normal), but it won''t speed upten km/h without it taking about 35 seconds. Any suggestions on what the problem is or is this normal but there''s an Oldstrick (:P) to improving it?? [img]smileys/smiley19.gif[/img]

 

not really familiar with this model. is it carburetor or fuel injected. have you used any fuel cleaning additive?

 

I have the same problem in my carbeurated 84 with the 3.8.... i cant figure it out either..... let me know if you get any good ideas

 

Yeah its got the carb sittin'' on top. EFI didn''t come until either ''89 or ''90, I can''t remember. It gets alright fuel mileage, but it was much better before this problem. I''m inclined to think it''s maybe a sticky rotor cap; i''ve already replaced the vacuum hoses so i''m inclined to think it''s mehanical. I''m not sure. I work F/T at a heavy duty shop but they don''t work on carbs, so i''m alone on this one... [img]smileys/smiley2.gif[/img]

 

i''ve also tried additives and carb cleaner as well, even the warm water-down-the-carb trick while the car is runnin'' warm, but no solution ensues.
