Question about 1998 Mercury Sable

Open Question

Car feels like it is going to stall when idling at a stop

It does not happen all the time...but occasionally while at a stop my car will drop rpms and almost stall, then jump back up to a normal rpm. When this happens, it will happen multiple times until I start accelerating. I recently changed my fuel filter who the mechanic says was filthy. He wanted to change it to prevent a fuel pump problem in the future. Also, if it is a fuel pump how much will it cost to fix? The mechanic I go to says it will cost about $2,000.00....

SOURCE: rough idle

Mercury had a recall on 3.0 duratech motors in 2000 and 2001. If you get a fuel smell at startup then you might have a bad lower intake gasket, it could cause a miss if seal is cracked. Article No. 01-4-3 you can get it on AllData.

Also, check the PC rubber L piece that runs from the PVC valve to under the throttle control - it could be busted.

Make sure ignition wires are not cracked. If you haven't tuned it up in over 30-40K consider doing that.

SOURCE: I have a 96 Mercury

I have a 96 Grand Marquis with a similar problem. Also on the highway it would just conk out on me suddenly, almost felt like I was hitting the brakes, then it would pick up again. Eventually got to the point where it was stalling out on the highway and at red lights. One day it wouldn't start. Mechanic said the fuel filter was clogged solid. It has run well but every once in awhile still stalls out on me. From talking with other Grand Marquis owners and the mechanic the Mass Air Flow sensor may be to blame. He wanted to charge me $400 but I found the part online for about $85.

Periodically at idle chugs. When trying to rev for more RPMs it almost stalls and takes alot of chugging before it gets back up to proper RPMs in 1st gear.


Does this happen occasionally after a stop? My 02' did this- brake light switch was sticking. I noticed it one night, after the car started chugging, I happened to look in the back window and saw the brake lights were illuminated for a few seconds even though i was totally on the acc.
This was a huge recall- lots of cars involved. Call a stealership and have them run the VIN # to see if you fall into the recall

Rough idle on 1990 saab 900 convertible, 16V


Because the car has adaptive technology, it may take a while to reset and adjust to the new, cleaner and better conditions than those to which it had previously adapted.

Did you change the cap and rotor? if the plugs needed replacement, likely they do too

Possible other causes include:

loose or corroded connections to any electrical component you disturbed (make a checklist and tick them all off as you check them);

mis-reinstallation of any F.I. part disturbed(checklist again)

obstructed water flow through the AIC valve;

improper voltage output from the AIC valve (for LH 2.4 systems, should output 8 volt at idle, dropping as load increases; for LH 2.4.2 system output 7 volt at idle etc; testing between terminals)33 and 17 at disconnected LH connector;

possible problem with MAF.

Hope this helps

Trouble with my rpms


Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
