So it would seem. I bough the Jeep because I needed a 4 seat off road car for the family. This is my 3rd Jeep but the other 2 were 4.0l sixes. So far I am not a fan of the 2.5l. The last 4 years have been spent building VW based baja bugs - I am beginning to miss their reliability and simplicity. Originally this was going to be a off-road mostly toy but some life changes have made it necessary to re purpose it into a daily driver. Hence the need to get everything working well. Had I known this a few months ago I would have bought a TJ with a 4L. Oh well. Now back to getting this thing to run right.
