My runner got the engine and transmission burned and I get another engine and transmission with 97K for 600 hundred bucks, so I switched engine and transmission, I did follow all the specification, something went bad with the damper and I use JB weld to fix it and stopped the leak, it works, I replace all the vacuum lines but I still have a problem with one that is attached to fender and have a white and blue in between, I dont remember the exact location so I stuffed aside to the vacuum line white and orange, I have a pulsation on the engine with the car stopped brakes applied and in drive, can someone help me what would be the problem please, I'm new in this forum, just asking for help.
