Question about 1992 Buick LeSabre
I had the distributor and carburetors rebuilt, what else could be the problem
Hello, Ok this can be several things but they do not have to be difficult. I would change your spark plugs and wires. I would change your fuel, oil, air, filters. I would check your EGR vavle and systems. This could possibly as well be a slipping clutch in your transmission is this between shifts or no? I would check your vaccum lines and hoses and also your throttle body. I would pretty much assume one of your vaccum lines on your careburator has a small pin hole in it or is connected wrong. I hope this helps you!

I believe this year had a temprature compensator on the side of each carb, these can cause hesatation, also all these carbs, and stromberg cv carbs benefit in being set a little rich at tickover. Finally what oil are you using in the damper? the oil needs to be quite thin (sadly this tends to leak out quickly, top up often)

First, you need to check fuel delivery and spark, or spark and fuel integrity. You can check spark by running the car with one wire off at a time and listen for running change,or lack thereof, if you see no change upon pulling a particular wire, possibly that is the faulty ignition lead or bad spark plug. you can also run the car at night and look for high tension leaks on the wires and distributor cap in the dark--- they show up very well. If your ignition seems to be o.k. then look at fuel delivery. Pull the supply line off the carbs and have someone turn the key on and watch for steady flow. Then repeat the test with the tube immersed in the can and look for bubbles in the fuel; if there are bubbles then there is a leak in the fuel supply line somewhere from the pump to the carbs which you must remedy. If it is neither of these, then look at yo. ur fuel filter and possibly change it---put on the clear type, not the steel canister style that you cannot visually check. also consider looking at spraying some carb cleaner through the throats of the carbs to clean the workings. But don't go buying things willy nilly until you perform some simple checks. If the car has points (still) then check the condition of the contacts, the rotor, and also the condenser, sometimes condensers fail, and everything else can be fine. Many engine malfunction checks like this are in your Haynes manual. Matt J
