Replying to: cb70 (Apr 11, 2003 8:51 am) Insufficient EGR flow. Mass air flow problem (hot wire), and turbocharger airflow. My warranty expired about a month ago. My mechanic told me there is bulletin out on the same issue and I do not what it means. |

My mechanic read code for Check Engine Light problems as follows: Insufficient flow through EGR, code P0401 Mass airflow circuit, code P0101, and Turbocharger flow,code P0299 Malfunction. Only about a month agoe the dealer serviced the vehicle, changed air filter, oil and so forth. What I understand, these items are not covered by warranty. Is this problem wide spread or isolated one?

I am new to this Jeep diesel experience and have an '06 Liberty with 20000 miles. I have had numerous diesels in the past, and am familiar with diesel quirks. I was getting about 20-21mpg overall and decided to put an edge chip to get some better mileage. I have never chipped a diesel before and was wondering which setting would yield the best mileage. 1st setting is stock hp and torque. 2nd setting adds 15 hp and the 3rd setting adds 25 hp. The manual does not clearly state which settings should be used, except that the 3rd setting should not be used for towing or hot weather. Any help would be appreciated for getting my maximum mileage.

Replying to: ratsass (Jun 01, 2009 9:09 pm) here is a few suggestions for better mileage.. When on the highway don't drive faster than 65 mph , you will find a lose of 20 % . rather stay in the trucking lane far away from trucks and cars, give your self space, drink a coffee and put some news or music leave 10 minutes early for work and put it in cruise control. the method is drive up to 65 mph then then to 55 mph. you'll notice when you call up your over head display on mileage and reset that there is a "big " difference in mileage after this point. "use the cruise" -Also changing the oil to the recommended 0 W 40 mobile every 7K miles, , when going on a long trip , - fill up on.. recpmmended.."premium fuels", anything that is better than the regular cheapest fuel on the block" for eg... B.P Premium diesel Sonoco "red" Shell "V power" ultra diesel Look for the higher " cetane type diesel fuels". and start using a cetane improver fuel additive like Power service or stanadyne , or maybe even lucas formula for upper cylinder lube. -The next step is pumping your tires to 38 psi , and hoping you have your summer tires on not the monster mudder lugs .. I am also hoping you did the fluid changes on the tranny and differencials as well. Over all you'll notice a "big change in performance " when you do these little things. It worked for me , and now with fresh fuel , I am peaking at 38 mpg Ca. but my baby has 100,000 miles on her. so she is broken in , you may have this until 30,000 miles on yours . but try it . good luck .. Lightnin..

Replying to: kesh25 (May 30, 2009 2:14 pm) I haven't seen the MAF code, but I wouldn't worry about it. You might try "blowing the nose" and see if the EGR will unstick. It is an expensive fix, I have disabled it to solve the problem, along with intermittent stalls.
