Hello, I am driving a 99 ford ranger manual 4-cyl. Recently, it has been having a tough time staying running. It seems to turn over fine, but i have to give it extra gas for a while, or the whole thing dies. as long as i give it a little gas, especially during idle times, it seems to drive fine. a peculiar thing is that after ive been driving it for a while, (10 minutes at least), it no longer requires me to gas it during idling, however it seems to have this sort of rumbling cycle where it will almost quit, and i notice the voltmeter dips as well. I have taken it into a few places, and i get no clear answer. the battery is new. someone suggested that it might be the alternator, another place said it couldnt be the alternator. I am afraid that if i cant figure it out soon, it will get worse, and ill end up having to take it into a place and spending way too much. at any rate, if anyone has any ideas, i would be very appreciative.
thanks,
Mark

I would take it to Auto Zone or Advance Auto and have them check the charging system

99 Ford Ranger. All this advice about sensors, plugs etc.. I have never heard of an alternator affecting the running of an engine. This vehicle has obd 2 so the mil ( check engine) lite would be on if there were any of the conditions related to the emission system.
This problem takes some hands on to solve.

I have a 99 ranger, 183,000 miles on it. HAd similar problem. Does yours have 2 plugs per cylinder, mine does? Dont ask me why, but anyway 1 spark plug coils had a hole burnt in it where the plug wire plugs into it. It was on the back side so you could'nt see it. A mechanic found it. Also another time it was running ruff, so I just got a can of carb cleaner and gave injecters, cables, linkages a good bath. that worked to.

it sounds like the idle air control, the EGR valve could be stuck, but the cycle is common in ford 4 cyl engines with a idle air control problem, you may need to clean the throttle body unit with carbon remover like sea foam. Another possible problem is coolant temp sensor. You just need to test each of these things.

Could be one of two things:
A) A vacuum hose came off the intake manifold and is causing a lean condition.
B) EGR (exhaust gas recirculator) valve is sticking open, causing the exhaust gasses to vent back into the intake into the engine.
This is only supose to open durring moderate acceleration to reduce engine detonation. (or knock)
First thing I'd do is pop the hood and listen for a slight sucking noise where a small hose may have come off. You may want to feel around the intake manifold for an open vacuum port or loose hose.
The EGR is a little tougher to diagnose, and you may want to ask someone with a little backround in engines to check for you.

I have a 98 ranger doing the same thing. Mine turned out to be a bad EGR valve. It was running fine while moving and idling fairly well if idle for say 1-2min it would almost die and all gauges would drop even the volt meter, and sometimes it would die...Thanks

Look around in the engine compartment for a vacuum line that possibly fell off or if has been a while since it was tuned it could need some sparkplugs, also a dirty air filter will create problems although if that was restricted you would be having problems when it was warmed up more than when its cold, If it happened all at once check for a hissing vacuum line while engine is running to see if one fell off.

i own a repairs shop in Tennessee and you need to take it by any advance auto parts store and have them do a check on the alternator before coming to any decision on it,i have seen the alternator do this before ,but it don't seem lie that the cause for what yours is doing,id have it checked out before Any work got done on it at all because this is one of those things that can start as being one thing and turn out to be another thing so have it checked and then see what they say about it,at least you,ll know for sure ,,good luck i hope this help,s.

I had a car that did the same thing and it was the idling sensor it easy thing to change so i would try that first the thing with the volt meter is nothing it does that just because the motor is idling to low that is all.

notice what is going on when the truck has a problem. for instance do you have the lights, radio, heat or a/c?
the best to to ensure a vehicle runs good is to ensure the proper maintenance is done. plugs, wires and all.
