Question about 1993 Ford Aerostar Extended

1 Answer

'93 Aerostar-stalls while driving/scary-stalls in 'drive' at stops

Starts fine..stutters in 'idle'-battery needle bounces wildly...try to throw it into gear and give it gas..lurching violently into motion..lightly pumping the gas until the engine has a chance to warm..after five minutes or show it's fine. today I give it enough gas to be going 50..I'm going 25 ( air/fuel ) when I'm climbing a hill a flopping,clanking noise accompanies my acceleration..as I slow and take my foot off the gas I stall completely, losing power brakes and steering (yipes!)..I pull over and start the engine and it works fine for 5 minutes and the process repeats itself...is it an oxygen sensor issue,air intake..or a diabolical combo of 15 expensive possibilities? HELP! sell or fix?

Wow!!! Now that's a headfull of problems....
This could be a great many things...
Check these before you sell. I have a '93 Aerostar and can't live without it.
1. Check idle speed
2. Fuel filter may be clogged or water in the fuel system.
3. Choke improperly adjusted or sticking.
4. Distributor components damp or damaged.
5. Faulty emissions components.
6. Faulty or incorrectly gapped spark plugs/ Also check wires.
7. Vacuum leak at the carburetor/fuel injection unit or vacuum hoses.
8. On 1986 models, stalling during idle or deceleration may be caused by sludge in the throttlebody. (2.3 litre engine)
9. On 1986 & 1987 models with a 2.3 litre engine,hesitation or stalling during acceleration may be caused by carbon build-up on the intake valves.....I hope this helps!! Adios

2002 sequioa sudden stall


Often when the battery is disconnected or replaced the computer will lose it's learned idle settings. You could try letting the engine idle in park until the engine temperature comes up to normal and leave it like that for a few minutes, then put the Air con on and let it idle again for a few minutes, then switch the air con off and put it into drive. If it does not stall, let it idle in drive for 2 minutes or so, and then do the same with the Air con on. This should relearn the base idle settings and stop it from stalling on you. Before you carry out this procedure you should make sure that when you replaced the battery you didn't remove any other plugs or knocked anything that may be causing the fault. If you try this procedure and it still stall when you select drive, you will need to get a Mechanic to check the vehicle over.

Hope this helps,
Mark.

While in drive, the idle will bounce low and high, there is a stutter when you press on the gas peddle, has stalled while pressing/pumping gas pettle. have to hold gas peddle too keep from stalling when...


I have a 91 shadow and had a similar problem. Mine is fuel injected, and the quick fix was to just go buy some fuel injector cleaner, I reccomend STP, and throw that in the gas tank every fill up for about a month. Mine hasn't had the problem since.
