rolloffron

no warning lights at all when it acts up, also the truck will not idle more than about 2 min, if you don't bump the idle up, i had it at a mack dealer they replaced timing sensor? or crank sensor, truck used to idle very slow only about 350 rpm,so they re calibrated it to 700 but will still shut down if you don't bump up idle,they didn't have an answer as to why.

no,not the roller part that works fine,its the hinge at the floor that makes it stick.so i've been oiling that. i know this will probably sound crazy, but about a month ago i was running down a county highway truck was running perfectly, started to slow down with the jake for a stop,again running perfectly,stopped at the corner, go to take off,no power at all, sputtering,smoking blue as can be smoke, acted just like it was gelling up, go to the side of the road,engine seemed like it was trying to run with the jake on. shut it off change fuel filter,bled injectors 2 cyl, were getting no fuel, took mainline off blew it back into the tank. primed pump and bled injectors again this time all fuel. shut it off, restarted same thing,chugging, misfire, and smoke like hell, i had it about 1/4 to half throttle,and i guess frustration by this point got the better of me so i mashed it to the floor and let immediately off ,you know basicly slapped it down,3 times,and wala ran perfect. it has run good up until recently when acceleration gets erratic, the jake has always been hit or miss,but the throttle pedal has been sticky as long as i've been driving it.the floor is clean,no dirt build up on it.

i have a 95 cl 700 too,and it does the same darn thing,only if it's damp or rainy weather it's a 427 coolant is full,and oil full too, i don't get it.

hi,sorry for the bad puntuation,i'm not a typer. i have a 1995 cl-700,and i'm not sure if it has a bad throttle pedal,or some other electrical issue,the jake brake,now i'm not sure if it is an actual "jacobs" brake or if it's a dynatard, what it does,is you can have it on "high" and sometimes it does nothing or very very little to slow you down.sometimes it will work like it should, it mostly won't work unless the engine is at 180 degrees.the other issue is with the throttle mostly it will rev up to 2100 in the lower gears,then once you get to 7th and higher it is slow response and seems like it cuts out at about 1600,if you "pump" the pedal it will sort of throttle up but very slowly. it's an E7-427. it has supposedly had the valves adjusted,and it's had cam sensor put on it. some of the time the truck is an absolute powerhouse,then all of a sudden the power goes away and it slowly throttles up.it's an electronic throttle pedal,and i've been oiling the hinge on floor mount because the pedal it hard to push from an idle. anyone have some ideas for me?
