i got a 2004 jeep wj with the 4.0l i went to start it this morning and it started at 400 rpm gave it some gas for about 30 sec it started idling at 1k rpm and after it got warm it was working perfect i seen where you need to clean the intake blades but what else could it be i don't have much money but it's the only truck i got for 2 people to get back and forth to work, it was 34 outside about 6am and i tried it again at 2 pm and it started and idled at 1k rpm and it was 50 out it's drove me crazy just changed the 02 sensor and changed the oil so i know them isn't a problem anymore
