2000 Ford Ranger engine stalling

Which engine do you have?

2.5

I see that code says intake air temperature sensor intermittent nothing to do with the throttle position sensor.Do you have a scan tool that can read live data like intake air temp sensor?

I am sorry looked up the wrong code looked up code P1115 by mistake.Do you have a scan tool you can read the throttle position sensor on and mass air flow sensor on?Since that code is for tps inconsistent with Maf sensor.

Also have you tried cleaning the mass air flow sensor with mass air flow sensor cleaner to see if it runs any different?

Yes i do have a code reader. just put a new 80.00 maf sensor on it in June. put new tps on it today.
I'm just wondering if the maf sensor went bad already. the starter wont turn over on it now si i cant start it and
read the live data
Thanks

So the starter is inop you have a no crank no start?Does the starter make any noise when trying to start it?Also you can watch the tps reading with the key in the run position while moving the gas pedal and watching your scan tool.

correct. no noise at all. friend is going to remove starter tonight. Is it possible that the maf sensor failed after 3 weeks?
Bought it from rock auto

Anything is possible do you have a k and n air filter ontthat? Before you remove the starter see if you have power to the small trigger wire on the starter with the key in the start position?

I just have a stock filter. Ok ill have him do it

Alright keep me posted.

Changed the o2 sensor and got rid of the code. Engine has lack of power and stalls when cold. when it warms up
it runs fine. no codes

So you have the lack of power all the time?And it only stalls when cold?

No , just when it's cold. Then it seems as soon as the engine warms up runs perfect.

Have you checked the coolant temp sensor yet?

No I havent

If the lack of power and stalling only happen when cold I would check the coolant temp sensor.

Just changed the ect sensor yesterday. The truck still stalls at lights and stop
signs. still have some loss of power at take off.

Did it get any better with the new coolant temp sensor?

No it actually got worse. I think its the wrong sensor, so i'm going to put the old one back on. the end of it didn't look like the one i took out.

What brand and part number was the part you installed?

motorcraft dy-1144 I do believe this one they sent me was for a 3.0 instead of a 2.5 because the original was shaped like a cone and the new one was shaped like the firing end of a 22 bullet

First pic is is the oem
second is the replacement they sent me.

Does your old coolant temp sensor look like the one I posted a pic of?

correction 1st is the replacement

no that looks like the one for the gauge. this looks like the oem

I will send both pics side by side. 1st is the oem
second is the the replacement they sent me.

The pic you just posted is for the dy1144 so maybe the one you got was miss boxed if its different.

Well i changed the ect sensor and still have an issue with stalling. doesn't happen all the time., just once in a while. Sometimes at stop lights somtimes at idle when it's in park.

Sounds like its running better if the power loss I gone.Have you checked the throttle body for being all carboned up and also inspected idle air control valve being carbone up/sticking/failing.

Not Yet but i will this week. With the iac valve being 7 months old and the truck running poorly for a few weeks, would it be possible for it to carbon up that quickly?

It doesn't seem to idle up when the air conditioning turns on.

I would check it for carbon and the wiring going to it.

Ok finally put a new iac valve on it and ect sensor. Runs well and doesn't stall at lights or stop signs. drove it 3 miles and shut it off for 10 minutes to run and errand and started it back up and ran fine for 15 seconds before stalling again.
Started easy and ran fine. what's causing the stall in park after it cools down for
a bit?
Thanks

So it runs fine when its warm but stallls when the engine is cold?Do you have any codes still?

yes it still does. i was told to
remove B- cable to erase old idle memory. now it's back to no power when I
give it gas till it warms up.

No codes yet.
