Default 88 ranger 2.3 idles rough and bogs at full pedal

i just got my first truck. 88 ford ranger 2.3. needed a new fuel pump to make it run. drove it once to school and back and my brakes locked up. fixed that then my tranny blew. swapped a tranny and now i have another problem. I drove the past 3 days to and from work and school. it was rather cool the past few days. today was much hotter. i drove from work into town, then from town to my house, as i was driving i noticed i was losing some power, but dismissed it as it was no big deal. as i got home, i had lost a bit more power. still i thought no big deal. i get home and talk to my family for about 15 minutes. as i get ready to leave i noticed my power loss was still there. i turn onto the highway and floor it to get up to speed, i go from 6k rpm and lose all power until 2k rpm. from there if i keep it held to the floor it will only run around 2-3k rpm and wont go any higher. however i can run it at 3/4 pedal and it will run fine, until i get it hotter. the hotter it gets the less pedal i can press until it does the 2-3 k rpm thing. if i get it any hotter than not being able to even press the pedal, it imply dies. and will not restart unless i give it time to cool off.

----------

i should also add it chugsfuel like a sunuva gun. ive only driven it 30 miles the past 2 days and im at 3/4 tank. could that also be solved by fixing this problem?

I would check fuel pressure & pressure regulator function. A bad regulator could/would allow excessive fuel through the injectors as the pressure could be too high. If yours has a vacuum line, remove it and take a whiff to see if it smells of fuel. If so, the diaphragm may be ruptured, allowing fuel leakage through the vacuum line AND higher than normal fuel pressure to the injectors.
Take a look at the inside of the MAF, the sensor near the air cleaner. It uses two pieces of thin wire to measure how much air is coming into the engine. If the wires are dirty, they won't report properly. THEY ARE FRAGILE, so don't mess with them too much. You can use a spray cleaner or a small brush to clean the elements carefully.

i done some searching on the maf. the 2.3 model didnt come with one back in 1988. i did however take off the iacv (idle air control valve) and have a look at it. all parts inside were clean as a whistle.
sometime soon i will be doing a fuel pressure test to see if the fuel pressure acts weird when the truck begins having problems.

----------

i should also add that if the truck begins having problems, i can turn the key off and turn it back on and it will run fine for a few miles. if it happens again i can shut it off and turn it back on again. after a few times of doing this it will eventually quit bogging down, but will get god awful mileage and have no power.

No MAF on the 88. I have some issues with mine not idling right, low power, etc. My research has led to the MAP sensor mounted on the firewall, vacuum leaks, TPS, and timing. I haven't noticed poor mileage, but my fuel gauge doesn't work yet.....

Keep in mind that I have not gotten mine running properly as yet. Work will progress if I ever get back home again.

I knew that....

Sorry, didn't pay attention to the year detail.

The MAP measures manifold absolute pressure, more or less manifold vacuum, to tell whether the engine is idling or working hard. That signal is sent to the computer to help it regulate the amount of fuel to be injected. Hard work, need more fuel, lazing at idle, send less. If the MAP goes nutz, the idle will likely be all over the place, very very irregular. Fuel mileage may fall in the dumper.
If the ignition is good, plugs, wires, rotor, cap, coil, and TFI, it should run ok if the mechanicals of the engine are good, AND there is fuel supplied.
A new fuel pump, was it the in-tank lift pump or the pump on the frame rail? Or do you have the more modern(30+ year old...) single pump system? There should be a 'sock' on the pump or fuel pickup in the tank. It may get clogged and limit fuel flow, or the filter may be clogged, again limiting fuel flow. It is either a lack of fuel or a plugging of the exhaust that will lead to 'loss of power as it runs...', in most cases.
If you have a fuel pressure gauge, you can connect it, and tape it to the windshield, and watch pressure to see if it drops when you lose power.

all new plugs wires tfi and all that. when i first got it i replaced the in tank pump and all that. the frame rail one i took off and inspected it works fine. however when i took off the first fuel filter-the one that goes before the second fuel pump-there wasnt a filter inside the canister so i put one in. just took it out yesterday and it wasnt looking too hot but im gonna have to cycle thru a few filters before i am able to gt all the gunk out. i did some research on the map as well and i think im gonna have a look at that. may need a new one.



also i forgot to add that when i rev up the engine as it idles back down it skips from 1.5k rpm to 800rpm on its way back down. i cant quite tell what would make it do that but i think if i get this problem out of the way then most of the other problems can be cleared up.

update


got a new map sensor today because i used a multimeter on the old one and nothing was showing. plugged the new one in and got it all set up, took off the neg terminal nd put it back on after 10 minutes. still does the same thing. should i let it sit longer with no negative terminal or did o'reillys just screw me over. i have a warranty on the new part if i need to take it back.

i just really wanna get this truck to be dependable and reliable like ford says they make it.

After some time, FoMoCo started using the canister on the frame rail for 'surge' supply to the high pressure pump upstream on the rail. They quit putting filters inside.
Check that there is/is not a filter further towards the injectors. If there is another filter, you don't need the canister filter.
I'd still get a fuel gauge and tape it on the windshield. Cackling and popping indicate, to me, to look to the fuel supply, sticking valves, or lean fuel condition. You might want to consider looking at checking the TPS. If it has dropout, the computer will want to cut back fuel supply to match throttle position, and the engine should seem as if it is running out of gas(which it is, sorta).

will do. planned on looking at the tps in the first place.

took a look at the tps. it was perfectly fine ohmed it ad tested voltage. all read good and clear. goa borrowa fuel pressue gauge from o'reillys an check an see if is my fuel pumps or filters messing up. till then i just pay the waiting game

yeah, when i first got it, it didnt have one, ill note that, i had one inside it but it was nasty and had nasty clogs in it, so i took it out, it was a you-know-what to get that o-ring to seat, so im not going to be putting another in there. thank you for the tip.
