OK here is the deal. I recently replaced my intake manifold gaskets, rocker arm cover gaskets, and fuel injector o-rings on my 2.8 ltr MPFI v6. I've got it reasembled, and its not working right.

Here is what its doing
Starts but the rpm immedetaly drops down to 0 and teh car stalls immedetaly onless I hold down the throttle to about 2000 rpm
Hi pitch squealing sound coming form engine. The sound gets higher and higher when the rpms go up
White smoke coming form the exhaust manifolds

I'm out of ideas, i hope someone can help

You've not got the manifold sealed properly, and you have a bad vaccum leak. Also, the smoke sounds like coolant getting burned off. You may have a blown headgasket, improperly selaed intake manifold gasket, or a cracked head to cause that. Take it to a shop and let them look at it.

any other suggestions, plus the timing is screwed up on it so it wount stand there and idle, how can it be driven?

Well, here's the smart-*** answer...by fixing it.

now, something helpful:
If you replaced the lower manifold seal, then I bet you are leaking coolant into the motor as stated above. You'll have to rip it apart and redo it if that's the case.

does the white smoke smell like oil or antifreeze?

It doesnt smell like oil, and I've never smelt antifreeze so i don't know.

talking with some friends its a vaccum leak (duh), so I'm tearing into it again tomorrow and re sealing the intake.

wish me luck

Problem fixed as of now. one of the intake gaskets slipped and the manifold wasnt torqued down enough. Thanks to everyone who helped

is the engine running rough? like really rough and when you drive it there is no power?

check to see if your injectors are working.

i had 3 injectors stop and my engine steamed and smoked like crazy
