  1. R mack with five speed. In gears 4 and 5 around 30ish mph I have a vibration and doesn't matter if it's in gear in neutral or coasting with clutch pushed in I have this vibration. Sitting still revving motor or running in all other gears including 5th over 30mph it's smooth. Any thoughts? Thanks

  2. 2008 cxu overheats and shuts down during parked regen. Wasn't there when it happened so not sure if engine fan was running. I do know in the summer time while sitting still the engine fan won't run while a/c is on sitting still which makes a/c blow warm air. Once you start driving and moving air through front end it's fine. Didn't know if this fan issue could be the culprit for both problems. Thanks

  3. Took for test drive and still acts up. Noticed it only cuts in and out when pedal is pushed all the way down, let off pedal a little bit and it runs smooth. Could this be a peddle issue or something at pump. Is there a way to check the pedal for intermittent voltage? Thanks

  4. Thanks for the replies. I cut the wires on either side of plug and used a sealed connector and heat shrink to reconnected them. Before I did this I could get the truck to misfire while idling while moving the plug around. Now it seems to idle fine, going for test drive tomorrow. Thanks

  5. Does anybody have a schematic of that plug? I pulled the plug apart and the one terminal had the plastic guide broke off and the spade is discolored. The two wires going in and out of the plug at that position have a zip tie on then as if its been a problem for the previous owner. Thanks

  6. 1995 CL 613 with 427 and inline injection pump cuts in and out while pulling empty or loaded. Only acts up for short time then goes back to normal. Tried new fuel filters and new lift pump and still same thing. Was wondering something with pump or injectors or something electrical like the throttle pedal?

  7. Everybody keeps talking about the exhaust side and intake pipes and hoses. Have you looked at the actual intake manifold itself? Last time we had a whine like that it was 3 broken intake manifold bolts on the bottom side. To make it hard to find, the bolts were broke, but the bolt heads were still in the holes so it was hard to see anything out of the ordinary until you shined a flashlight on the bottom side of intake and could see were the gasket was slightly pushed out.

  8. What I've found is the volt gauge wasn't reading anything, when i put a charger on the batteries it still didn't register any volts, but i tapped on the gauge and volts showed 13 to 14 then my signals worked with the lights on. The batteries are pretty much dead. Always have trouble with these six volts going dead. How hard to go to 12 volt system?
