1987 sentra stalling problems

rothchild · Jun 21st, 2006, 07:29 PM

My sentra seems to run great on the street as well as the highway, but seems to instantly stall as I come to a stop. It will not idle at all except when it is cold at start ups. Ive changed the plugs, wires, rotar cap & button, fuel filter, cleaned the carb with gumout spray, and checked for vacume leaks. I know that others have had similar problems, but this really has me puzzled. Are there any suggestions to my problem?

If it idles when cold I would say the fast idle curcuit is working properly. Have you tried adjusting the warm idle adjuster screw?
Also to check for vacuume leaks You can use a can of starter fluid to spray around all the hoses and the intake manifold to check for a leak. If the engine changes RPMs when you spray it you probbaly have a leak.
Sorry I can't help much

where would the warm idles adjuster screw be located on an '87? I've found many around that carb that could be adjusted
