when i try to start it with iac off and disconnected from wire the engine stalls immediately

 

found the screw and looked right and accidentally turned it the wrong way. But when i screwed the right way the idle didn't seem to change until i turned it counter clockwise a lot i readjusted it back to normal rpm.

 

??
Not sure what to say then

It will be the only screw on throttle linkage, probably has a spring around it, holds the throttle plate open a bit when its closed...............

 

found it. read previous post

 

drove 20 miles then decided to look at LTFT, LTFT 1 was 7.72% and other was 3.12% press on accelerator LTFT goes down to 3.52% and 1.17%. I have a small vaccum leak and idk where...

 

along with small vacuum leak guess what else i found... something that looks like it bolts onto something. Its on the ac compressor line

 

Those LTFT numbers are OK, any thing between -10 and +10 is OK when cruising or at steady RPM

looks like an AC hose, if you can't see/find where bracket attached cut it off

 

Alright well im gonna try to replace the power steering pulley again tomorrow (its hard) heres a video of the some play in ac compressor pulley. And the power steering.

Not sure why you are replacing the power steering "pulley"?

The bearings are inside the pump part, if thats the part that was vibrating then changing the pulley won't help

Did you check all the other bearings?
alternator, water pump, fan clutch, idler, tensioner
AC clutch?

 

oh well damn i was about to replace the power steering pully. The pully has end play as seen in the vid. So thats the whole pump not the pulley? Also everything feels good. Did you see ac compressor play in the video? AC compressor pulley was first. then power steering pump

 

idk i might just go to a auto shop. Out of ideas and fixes

 

What you were touching on the A/C compressor was the clutch part. It engages when it's turned on. The pulley is where you see the grooves, it should turn freely and not grind, rattle, etc. Your P/S pump appears to have significant play in it. The thing you found on the A/C line is just a bracket to to hold the line that someone failed to refasten.

 

So could that power steering pump cause engine to shake? Do I need to replace the whole thing? Do I need to replace ac compressor?

 

AS Grampa said up above regarding your AC Compressor and as I saw in your video, what you were pushing on on the AC is the clutch, that is normal and will only turn when the AC is on with the engine running. The pully with grooves just behind it on the AC is the free wheeling pully for the AC, so what you show for the AC in the Video is Normal. Now for the PS Pump Pulley you may need to replace the pump as the pulley rides on the pump's shaft and if there is play on the shaft any pulley attached to it will have the same end result.

 

I just fixed an issue with my truck that had some of the same issues youre describing. Before pulling your fuel injectors, maybe check for cracks on your ignition coil. Perhaps your misfires are not bad enough to throw a code.

 

I took my truck to a shop and the guy said it looks like its just what i have. Meaning its normal. The engine vibration. But he said he would more tomorrow to see if he finds anything else. But 10-11 mpg seems low for my taste

 

Yes, it is low, upper teens for 3.0l in a Ranger would be normal, 17-19mpg

 

Let's assume engine vibration was normal. What would we look for low mpg? I used to get 250 miles to a tank 3-4 months ago and now I get 180. Idk what happened

 

With my 2003 XL regular cab, long bed with a shell, 3.0L with 259K miles, well maintained (a bit tired) I get on freeway drives between 19 to 21 MPG. City driving drops down to 15 to 17. Of course no burnouts or heavy footed acceleration keeping the RPMs either above 3500 RPM during hills or cruising at slightly above 2000 RPMs.

 

i do no heavy footing and still get bad gas mileage. I really don't wanna think its just an aging engine. idk whats wrong

 

Something is not right, how many miles do you have on yours? I shared what I get with mine (forgot to mention its an automatic) so you have something to compare too. HTH

 

mine is 2002 ranger edge auto trans 210k miles. I used to get like 250-260 per tank now only 180.

 

h

 

I think i'll have to deal with what i have on the gas mileage...
