So I just got a new 2.5 liter rebuild from Jasper put in professionally with the install kit. The kit includes all the bells and whistles like water pump hoses belts thermostats spark plugs distributor and so forth. I have a new problem there's no Rhyme or Reason to this problem. It only happens when I'm in first or second gear accelerating from a stop. It is not happening when I downshift and I have not felt it in 3rd 4th or 5th. It feels like when an engine used to choke out. It jerks a little bit. It does not rev up as if the clutch is slipping. Also when I got the new engine I got the clutch serviced as well with a new flywheel and clutch plate. When I try to recreate the problem I cannot it just happens randomly. It doesn't matter if the engine is warm or cold. There are no check engine lights so there's no codes. Any thoughts out there?
