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

i would re-check the enormous amount of vacuum lines on the passenger side. and the right side, too.
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
