check fuelline pressure...recently had to replace fuel filter and fuel pump. When you turn the key on listen in the back and see if you can hear the fuelpump turnig on. Use guage to see if fueline pressure is correct for your ride. Check and see if fuel filter is rusted and possibly plugged, it can restrict fuel and wear out fuelpump. I find original fuelfilters never changed before alot.Also, check throttle sensor. See My answer for other vehicle with throttle stickingstalls at stops for tips in checking and replace throttle sensors. I have replaced many on 80 on up to 2000's mainly on escorts, sables and torasses.....Marvelous.
Posibly the Throttle sensor. A rectangular metal box with 4 aluminum phillip screws on side of the engine by throttle body. Before removing get one from an auto salvage yard. They are normally alot cheaper and they take them off fairly new cars that were totalled. Take a large long phillip screw driver that fits the screw and put it in the screw and give it a few good whacks with a hammer to loosen screws. As screw threads become visible on all four spray screws with WD40 and turn srews back in to get holes lubed it will be easier to remove the screws after about five minutes,Aluminum screws into thicker metal tends to heat and cool weilding itself in place. Take off old rectangular cap and look inside for aluminum shavings and inspect throttle shaft. Throttle shaft should feel like it is riding on glass. If it appears okay clean area and blow out. Pick which one you want to put back on. Before closing I sprayed a little mild graphite spray on shaft seals or WD40. Hope this helps if no one else has a better idea. I have had several Sables and Torasses with this problem over the years.Worked for me. Also, I have found throttle cable brackets bent..Marvelous
I was told that the engine gets really hot on the side of the coil pack. It is recommended that you cake the engine side of coil pack with electricall gel. Three years now without a problem. Also they are usually about 25 bucks from auto salvage yard....alot of parts are new and taken off totalled cars...they save me a fortune in parts and most times if you find a good yard they will take it off for you and have it waiting for you if they remember you. So chew the fat with these people. When your one of us we tend to go out of our way to do good for a brother or sister wrench slinger.....Marvelous.
My father taught me early in life that you need to keep fuel dry. Each time you get gas there will be some water in the fuel. Most people only add a gasline antifreeze water dryer during winter when they fill up. My father said pretend in winter that 1/2 a tank is empty and put in a bottle about every third fillup or more often if the weather is below 20 degrees. This is a good practice but people need to add periodically during the warm weather too. Especially when it is hot dog days of summer. This will remove water purchased with gas and condensation in the top of your tank rolling back into the gas and it will prevent pressure lock. In the summer have you ever taken the gas cap off and the pressure almost knocks the cap out of your hand? Keep air filter clean. The trick is getting the right amount of air to the right amount of fuel. Poor air poor economy. Have you tried air tornado adapter goes in airline hose between aircleaner and induction door or carb on older vehicles?
On a Toyota the fan clutch seal was leaking oil very slowly so the fan was kicking fluids into alternator and filled coil that was built into the top of the starter. When you stopped it would stall. It was so slow that it was not visible till parts filled up with oil and shut the whole electrical system while sitting at a light. Replaced seal and replaced with used rebuilt coil and starter from starter shop as we noticed missing teeth on flywheel. Cleaned alternator and re gelled all electrical connections. Solved that problem. Make sure battery cables are totally cleaned.
on my gmc I had a crack in the plastic top of distributor. I changed that and about a week later it started again. My son in law came by that evening and we were standing in front as my daughter cranked it. The coil powerpack started arcing a spark to metal next to it. We replaced coil pack 25 bucks from auto salvage yard. Do not forget to cake on electrical connection gel on engine side of coil pack, it prevents engine heat from wearing it out pre maturely. That was three years ago...solved my problem.
If I switch back and forth it causes the left blinker to blink.
