I have a 95 Sport, code 13 and 41 came up. Code 41 has been on awhil. This morning code 13 came up. I replaced the MAP sensor and it still wont idle. It isnt bad at higher RPMs,but itll die if you let it idle. Anything else I should b looking at? Thanks

 

code 13 is a problem in the O2 sensor circuit, have you replaced the sensor and inspected the wiring?

code 41 is ignition circuit:
DTC - 41 Ignition control error
DTC - 41 MEM-CAL error
DTC - 41 C³I Cam Sensor Signal error

Is it running rich lots of black smoke from the exhaust?

 

my dad has a 95 cherokee sport let me check his jeep book at the codes real quick

 

to see if its running rich hold a white peice of paper like 6 inches behind tail pipe. if it dont turn black then its not running rich.

 

same thing in my dads book

 

This is exactly what came up when I plugged it in/ 13 No change between MAP during idle and baro pressure/

Thats why I replaced the Map sensor, should I be checking the 02 sensor as well.

 

No black smok. It will start but will not idle, it just wants to die. If you push the gas down slowly it will run at higher rpms. Its almost like its chocking itself out.

 

yea if you want to

 

like almost not enough air getting to it right. check the air filter. my 98 did that and the air filter was dirty.

 

just replaced it about a month ago

 

The 41 is usually "alternator" related.

What is the voltage gauge reading on the dash? Should be around 14 volts, give or take.

A marginal battery can definitely lead to STALLING. And if the alternator isn't charging the battery, that fits.

Have your charging system verified.

 

Code 13 had to do with my fuel pressure regulator. The one I replaced a week before went bad. The code 41 was a shot altenator. My guage read normal most of the time. I finally caught it low and then jumped up in the morning. Anyway, it would stay really low while it was warming up and then jump up to 14. It was the original one, not bad 180,000 miles on it.
