hey hey, new guy here

swapped an engine recently. I drove the good runner before engine purchase, and it ran great.

after swap I cant get her running right...and could use sum help

1995 3.0 dropped into a 1994 (3.0 had bad head gasket)

all went well install wise...starts immediatly

but after a lil warm up ...a min or two, engine begins surging or pulsing. stays running tho.

it then wont take throttle over 1500 rpm....just goes flat

swapped a lot of obvious things and looked for leaks....but my pea sized brain isnt overcoming the issue

any and all ideas welcome.....


thx
bro out

3vze has tons of opportunity for vacuum leaks due to all the pair/egr/vsv we have.

 

thx rtd33...

vac lines suck indeed....perhaps it is possible that a line would prevent proper acceleration

and....surging.

be nice to have a 2nd runner to view lines and proper plug ins.

am much better with visual than schematics!

Lots of times moving things around knocks dirt loose.

 

Fool filter was changed.....the

And I wonder if there isn't some vacuum device that has power over engines ability to rev
