Hey guys i just replaced the engine on my 99 dak 5.2 4x4 and there one thing that i cant figure out..

Here whats up.. idles great, driving good. but when i start off, shift to drive and hit the gas there a small delay and then starts moving... sometime when warmed up, it will just stall out. under the hood i was playing with the TB and when i hit the gas the engine just about dies for a sec and then catches up.. maybe short of fuel or air?? what do u guys think?? vacuum hose, fuel injector no idea...

let me know if you guys need more info

thanks

 

i dont know if this would be of use.. but the engine i put in is a 5.2 ram engine in the dak now

 

I would say the tps is bad but before you get one pressure test to see if you are getting enough fuel I want to say 45psi at idle but Im having a hard time remembering lol

 

i switched over the TB from my old 5.2 and still same story..

 

bump

anything else it can be besides fuel pump issues

 

sounds like a vacuum leak. to prove it, temporarily plug off all ports to the manifold. caution - you might not have power assist brakes and your transmission might not upshift with vac lines disconnected.
