Hook n ladder 1 Posted May 23, 2011 Share Posted May 23, 2011 Need your ideas men. 98 Ch 613 with reman 427. Never had any problems. I did pm yesterday, changed all filters etc. Truck running great. about 100 miles down highway it starts to buck alittle then smoothes out...did it a few times. i think the motor shut down but fired back up a few times. ( i was still in gear)then i seemed to lose power 1600 rpm then 15 etc. I got to 1400 and pulled into a rest area. Shut off engine, Opened hood. everything looked ok even filters were fine. Got back in and everything seemed fine. It may be running BARELY a little rougher. No check engine light either. Any ideas? Motor installed in 2008. I might have 25,000 miles on it.
