How to Fix a Car That Stalls: 7 Steps (with Pictures) - wikiHow

www.wikihow.com > ... > Cars > Car Maintenance and RepairwikiHowFortunately, this usually does not signal a major repair to your vehicle, and it cangenerally be ... Does the car idle roughly and stall when at idle? .... has been running for a while, the fuel pump may overheat and stop working, stalling the car.

Loss of power, but no mention of rough or inability to idle (including stalling). If those additional symptoms are part of the problem, check for a vacuum leak to the intake. Listen for hissing or sucking noises near air hoses. Look for loose, cracked, or broken air hose connections. Check PCV valve...Cheap to replace, could be sticking, then loosen after truck sitting with engine off. A vacuum leak will not give any light indications, and vehicle will seem to run normal when applying gas, but will want to stall or run rough (or want to stall) when at idle or sometimes when taking foot off gas when slowing down.

Did you ever figure out the problem with the miss on one cylinder ?

sounds like you have water in the fuel, put in a some dry gas and let it sit over night then drive it the next day to see if it improves

First of all there is a vacume leak, second how is the air filter?, tell the husband to change the MAF mass air flow sensor and I would also change the TEMP tempreature sensor.

Has the Fuel filter been changed? Clean the MAF the IAC and seafoam the intake. These things would be cheap to do first. Does it feel like a misfire? If so Id look into testing the coils Might need new plugs.

there is a small chance that something was knocked loose when they did the test. be that as it may you seem to have one or two problems. one of the sections of the coil pack may be failing and need to be replace. quick test for this is to pull one lead at a time from the coil pack to see if the engine idle changes. the other issue may very well be a vacuum leak. listen for a whisting sound at idle.
if you do need a coil pack the best (cheapest) way to get one is to drop by your local wrecking/recycling/junk yard. my ford windstar used the same coil pack as a toyota, it cost me $40 dollars as opposed to $160 at the dealer.

You need to see if you have any codes in computer, it may lead you in the right direction. That being said it sounds like you either have a idle control valve issue or a vaccum leak but I would see if you have any codes first. You can have codes without engine lamp on.

I would have to say your engine is probably shot. The bearings are probably gone. It is possible, i suppose, that your oil pump is faulty. As soon as the oil warms up, and becomes thin, the rods and lifters start to rattle. The same goes for the oil pump, as oil becomes hot, and thin, it may not be pumping properly. I would try a used oil pump, and see if there is any difference before i wrote the engine off.

low idle speed...or the need of a tune-up
