completely lost need some serious help with idle and low power

[Zalmoxis]

But idles 760-800

I've unplugged it and let it sit till I figured out something that didn't work out anyway :)) I put it back and the car caught a second wind man, it's not sluggish anymore spins the tires every corner ... But I still have a rough start !

Thanks that's what I thought ! I've reset the ECU the car gained hp it's running like new ! I'm not even joking guys!!! It's like she coughed the flegm.. Still has some issues at starting but it runs !!

how did you reset the ecu

I thinks that purple switch goes on the radiator of earlier models('88 verts and older). Tell them you have a '90 coupe and you should get the right one.

[Zalmoxis]

They are not the same ! I can't find a purple switch ! fuxk this switch ! I changed the other one just in case, I found a disconnected hose it was loosing vacuum I plugged it the car runs better .. But still no choke ..

[bmwcarnute30]

The plugs are different :-/ I can't find the purple one ... Online either ! I have a 90 325i if it makes a diff

the color of the sensor should correspond to the color of the connector if irc.

so the purple goes in the 2nd hole ?! If this fixes my car I'll sell you a t shaped ICV ;)

[bmwcarnute30]

I hope that will fix my idle ! I've changed two airflowmeters I have 3icv and everything else related ! If this won't do it then .. I'll
Shoot the block with a magnum and put a 1jz or ls! Neaahhh I'm just pissed :))) thanks bmwcarnute30 !! I think I know what you're saying !! Thanks ! Right on top of the front of the block on the right side by the valve cover ! I'm heading right now to the garage ! I'll keep you posted !

do you have a t shaped working icv for sale?

Since you probably took apart the C191 connector under the intake, I would make sure it is not corroded on either side where the wires feed in, under the rubber boots. That connector can be a big source of problems, even intermittent ones. Any problems can get worse if the connector is disturbed since the corroded wires are usually holding on by a thread...

[bmwcarnute30]

I would still do it, the fact that the head was rebuilt even lends more to a valve issue.

Also, what issue caused you to rebuild the head?

I don't see it much on this forum but more old-timey mechanics will do a compression test with nearly any new problem to rule out serious problems and create a base line to work from.

i was pulling the intake to get the injectors cleaned and then it turned into a while you're in there project.
anyway it seems almost like im running on 5 cylinders. im going to check to see if im getting spark at all 6 when i get the chance and the report back.

if not ill bring it to work and do a compression test
