hi, what i did i went to dealer and left my wk for 4 days, all this time they tried to find a problem, after they get reply from jeep to update the pcm firmware they did that, but i still have problem but now my needle is steady now but still vibration exist.
anyway today i had again problem it nearly stalled at traffic lights!!!
i got no warranty now!!!
Merlin if i was in dealer to sort the problem and i took my jeep back and after still problem exist can i take it back to dealer to do work under warranty.
i mean the same problem not other, when i took jeep from dealer my warranty expired after a week but problem still there.
thanks

Hi Merlin, i have the same problem, my jeep is a WK 2005 4.7 L V8 Laredo 4wd, i changed the 4 o2 sensor by new oem ones, and still have P0430 and P2096, the pcm shows a label:

SOFTWARE UPDATE
MODULE P/N P56044552AL
MODULE S/N TEH014552BUS RENUE SEQUENCE # 549220

i would like to know if this is the last software or what is the last one number to ask? i know that exist many tsb's, but wich one correspond to my jeep?.

thanks, Juan

Hi
That goes to number 68055273AA and TSB 18-034-05 best describes your fault codes.
Good luck,
Regards,
Merlin

ya know thats weird, two years ago before i bought my current 5.7 jgc i test drove a 4.7L jgc and it had a slight miss in it also while crusing around. thought it might be related to ignition or ac compressor cycling. that was the only reason i didn't buy it though.
