On the back of the engine are some vacuum lines that get damaged.either that or the throttle position sensor is not working properly.it is located on the throttle body.

2001 Mercury Sable - already asked but this is in better detail???


Not plugs. Go to AutoZone, Advance, or Oreilys autoparts for a FREE scan. Bring pen and paper and write down trouble Code that their scanner shows. Clerk should be able to tell you, but you want the Code so your can price repair.
Once you get Codes you can call and price work. A few can be done without much effort. Unfortunately the ABS may be a victim of heavy braking. The ABS can be checked with a better scanner(Not all are equal).
Try tightening the gascap, although each time you added fuel additives you did that, know that one Code may be related to a loose cap.
Think back about your gas purchase. The cheapest is E85. If you put this in your car, it is not made for it. If this is what happened, then it will give a Mechanic a better idea of everything broken.

2002 regal would slow down going up hills then


the catalytic converter most likely is no the sorurce of the problem, older design bead type Cat converters used to plug, but it is very rare on the newer ceramic honeycomb cats, u need to have the electronic engine control tested, are u getting a check engije light? if not has the fuel filter been replaced every 30,000 miles? also a part called the Mass Airflow sensor can cause these symptoms as well as igntion system problems.

2 times now when my 2002 Mercury Sable was low on gas (about 1/8 tank) it died while driving. Both times while it was in the process of dying, it wasn't running rough or RPMs going crazy, the RPMs just...


Sounds like your gas guage isn't accurate. A fuel pump is not designed to draw fuel from the tank until it is completly dry. This is to avoid sucking up all the debris on the bottom of the tank.

Oil smells like gas


sometime you will get this smell if you go a little over your oil change time of every 3000 miles also check when you replace the PVC valve normally in top of the valve cover gasket cause this will cut back on the ventilation that is needed to go through your engine if you take it off and it rattles it is still good but if it has been a while since you changed it it would be a good idea to change it also

1995 Saab 900S engine cutting off after drop in RPMs


Check the IAC valve and all vacuum lines. This link will take you to a DIY site showing where the valve is located on the naturally aspirated 4 cylinder Saab and how to clean it. If any vac lines look suspicious (dried, cracked or otherwise) replace all that you can get to. Vac leaks are notoriuos for causing poor drivability and stalling. Finally, clean out your throttle body and throttle plate and do a tune up if it has been a while (i.e. put in some new plugs, a new distributor rotor, a new air filter, etc.).
