Hey I just registered an account to say thank you for this thread!!
Had my Liberty MY06 for about 3 weeks, after a few days it felt kinda doey so I filled it with 98 fuel and it was sweet!
Then yesterday I was pulling up to a roundabout, stabbed the gas and it sputtered and coughed real bad WTF ?!?!
Then after reading this thread I reset the ECU, when I 1st turned the key it wouldnt start but then the 2nd time it started straight up
Warmed it up and then took it for a thrash and it felt smooth all the way up the rev range
So yeah!
thanks again, I thought I was going to have to take it in and spend $100's to get it checked out.
