max-throttle sensor location?

[m3outtanowhere]

there is a sensor on the intake manifold by the throttle cable that depresses at max throttle. The wire that plugs in is missing. The mechanic i went to is useless. he said that it is not functional! But my motor has flat spots at full throttle. My question is where does that wire go to from the sensor? mine is missing!

[m3outtanowhere]

anyone help? im at the end here trying to find it. im going to have to take apart my whole intake manifold. This is in place of a cruise control unit i think. Yesterday i got to look at 1996Bmw318TI's car and it is obviously a m44. But it was under a plastic cover. So i couldnt find it

[m3outtanowhere]

ok. it starts tomorrow. im gonna have to remove the manifold and try to find 1 wire and a clip. It plugs into a sensor that activated when the butterfly in the throttlebody is wide open.!!!!!!

i tried. No Luck! I feel like im talking to my self. I need help from someone with a m42. PLease...

Your mechanic might not be that useless. I have an M42 but not this switch.
Mine has cruise control cable there.

[m3outtanowhere]

does it only depress at max-throttle? is urs an m42? I dont have cruise. And it is a clubsport.

But what is this?

[Sergey]

My guess this switch is not a piece of stock equipment. Somebody added it to activate something (NOS? ) at full throttle and either didn't complete the installation or didn't complete the removal.

Is there a part number on that switch? If so run a search in realoem.com to see if is a BMW part.

thank you all so much for your help. you were correct. This car used to have a turbo on it and i spoke to a friend with a mutsui-gsT and he said aftermarket turbos that are seperate from the cars cpu would have many added on sensors. After looking at my car he concluded that it was a switch to close the wastegate at full throttle. But that mechanic was still a moron. LOOK AT THESE pics.

This mechainc, im not pointing fingers (Adams Independent BMW Service in Riverside), rebuilt my head and did not change the front main-seal or the SPARK PLUGS. Now he has since sold the shop (1 month) and im stuck with no warranty because the new owners dont even speak english. GODDAMN mexifornia. The boder policy does need to be fixed. Or at least a requirement to live in this nation should be to SPEAK ENGLISH!

O.K. I'm done

By the way all of the other threads that i have started in regards to idle-problems/r.p.m. flat spots/ erratic gas-mileage/ check codes...ect.I AM SORRY. All of these problems were due to rusted spark plugs. Yes, rusted spark plugs!!! I will never, ever, ever, have a mechanic work on my car again. Regardless of time, effort, or money situation. I have the knowledge just not the experience...yet. I[SIZE="3"]Vow That From This Day ForthI Will Never Let A Mechanic Touch my car again!

oh yea the pics...i was up all night going over the whole ignition system-because i was told specifically that the plugs were replaced
