HELP m30 running and idling issues

[vic_325]

other than the idle problem, i love the torque this engine has. its perfect for the e30! now its time i get a good clean paint job on my car.

well i have lots of time to bitch on the net while im at work... and thats mainly the reason why i dont have much time to put the thing back on lol...becuase of to much time at work. ill get to it.

lol, no worries

i removed that shit.

Ugh...

[vic_325]

Dude, its 2 nuts and a bolt to put the support back on... If you have time to be bitching about it on the net then you have plenty of time to slap it back on...

BMW put it there to brace the intake, stop premature failure of the intake gaskets and prevent cracking... Pritty much explains itself.

Good for you. I guess you can all do what you want but my $0.02 is to leave the damn thing on. BMW didn't put it there for no reason and it harms you in no way to leave it.

we made our own engine mounts. it does fit on.. i just forgot to put it on, and never got around to it. i want to know if bracket does anything for the vibrations, or is it just to brace the manifold

I just re-read what you said, you had a missing stud that makes sense lol

[Jean]

If he is using Joe Funk's mount the bracket won't fit and you'll need to make something custom.

didn't put that bracket back on. out of laziness......... coming to think of it maybe that bracket has alot to do with the shaking?

Uh, I would go put that bracket back on. Right now. 12 little metric nuts isn't really sufficient to hold that big intake manifold on imo.

[vic_325]

im running e30 manual harness and tps

[vic_325]

one of the two studs that holds the bracket underneath was missing. that threaded hole goes right through. so i plugged it up with a bolt... didn't put that bracket back on. out of laziness......... coming to think of it maybe that bracket has alot to do with the shaking?

[RickSloan]

just relized this sounds alot like a tps issue. are you running an auto or manual TPS? Was the I harness Auto or manual???

[Jean]

alright, i found the vacuum leak. it was the bolt that holds a sensor and the triangular bracket under the intake manifold. it runs smooth now at about 900rpm, but still after driving it stays around 1500-2000 and SLOWLY comes back down. once i get a decent exhaust with a place for the o2 it should be fine. ill clean the icv too.

Can you describe this further? The bolt/nut that holds the bracket on the drivers side, under the intake manifold shouldn't cause a vacuum leak?

[vic_325]

will check that out. ill even check the injector wires are in correct order aswell
