I have a bit if a problem with my 2005 Jeep wrangler

Customer Question

I have a bit if a problem with my 2005 Jeep wrangler unlimited. It started the random stalling issue about 2 months ago. Replaced the crank position sensor, cam position sensor, throttle position sensor and had the PCM checked and was cleared with no issues. It continues to stall out random times and is getting more frequent. I get the p0300 code along with p0032, p0038, p0052. Could it be the Opda?

I am not a mechanic so what do you mean by readings? Are you talking voltage?
Customer: replied 1 year ago.
No the throttle body was not cleaned
Expert:  Greg replied 1 year ago.

Okay no tools to check the live data reading on a scan tool .

Okay have the throttle body and IAC cleaned out and then retest .

Have if you can an exhaust back pressure test to see if you have a possible blocked catalytic converter

And do a fuel pressure test .

Ok I have had some other priorities arise and can get back to this issue. I do now have a scan tool to get some readings

Okay good after the last repairs did you clear all codes ,you probably did ..

Recheck now for any codes ,even if the check engine light is ON or OFF.
