problems
 

i have a 2002 ford ranger xl 2.3l and i have a few dtc's one of them was a code telling me that the truck was running to lean on the upstream o2 sensor then a second came up saying that it was running rich then my final code was a po1537 something about the intake well my truck died on me well it didnt die it wasnt running past 1000 rpm in drive and wouldnt drive past 5mph and every time i stepped on the throttle it would bog out how do i fix this problem

Welcome to FTE.

From your description of how it runs, sounds like you may have more than one problem & fuel delivery may be one of them, so post All of the actual trouble code Numbers, as they can provide good trouble shooting clues.

Did this problem come about slowly over time, or suddenly after some event????
Are you up to date on All past & present due scheduled maintenance???
How many miles on this ride????
The answers to these questions could help us make a more focused guess as to where best to look for your problem/s.

Hi
 

My 2002 Escape acted similarly. I found the catalytic converter had melted down and the exhaust had no where to go. If you put a 0 to 10 psi pressure gauge in your O2 sensor hole the pressure should be less than one psi. If it's more than that your catalytic converter may be have burned up maybe due to it running rich. If you think this may be what yiour looking for you can remove both O2 sensors and exhaust into the atmosphere and see if it runs any better. that would confirm it or dismiss it.

hello all,can somebody help me out with my 01 ranger,i keep getting codes 1132 and 1152.i replaced dpfe sensor,all 3 02 sensors,egr vavle,fuel filter,vacuum lines,spark plugs.still get cel,i dont know what else to do,feel like i keep throwing money away and not getting anywhere,sprayed around intake for leaks none to be found,also cleaned out the throttle body.anybody have any suggestions for me i would really appreciate t/y

Did you replace all the parts at one time?
Give us an idea on the repair sequence so we can help eliminate probable
cause and effects.

What kind of miles on the truck prior to repairs?
The two codes are FORD specific and HO2 sensor related.

Before you replaced any or all of the sensors and electrical parts did you
disconnect the NEG battery cable?

khadma,1st i replaced all 3 02 sensors,2nd egr valve,3rd dpfe sensor,then vacuum lines,fuel filter,then replaced plugs with proper gap of .042-.046,none of these corrected problem.keep getting same codes 1132 and 1152.i bought truck from father,had 119,000,its now at 124,600.everytime i work on it i disconnect battery so computer will reset itself

Are you using Motorcraft O2 sensors?

Check that the O2 sensors or getting power.

Check your fuel pressure or leaking injectors.

Are these the only two trouble codes?

Where are you located?

Is this truck flex fuel?

To "glackey88:" Welcome to FTE. This is a great site for help with your Ranger. It is also a place where some common courtesies are used.

Hijacking a thread is something that is discouraged. What you have done is sidetrack the issue the original poster (OP) started. Unless someone replying to either the OP or you specifies which person's issue, the responses get confused. Instead, what you should have done is to start a new thread.

Give it a try.

Give the new guy a break.

Although his problem is not the same it IS similar to the OPʻs.

AND I would like to think the OP corrected his problem since the first post

was nearly 7 months ago.

If you do start a new thread, let us know so we can follow.

Let us know the new tittle.

Give it a try!

khadma,the 02 sensors are upstreams bosche and down stream a denso.to test injectors ive never done.as far as flex fuel dont have anything saying flex fuel and where would i check to make sure if flex fuel or reg gas.i replace dpfe sensor when i used multimeter and ehow.com to test it,found not getting proper volts/ohms out of it.has for testing 02 sensor how do you test them.i was always taught that they either tell you your running rich or lean

just took maf sensor out cleaned it and then resetted computer,i forgot multimeter at my shop to measure the ohms on it so i got to pull it out again when i get my multimeter.
