Fault code P1633
Anyone have experience with this one? I've read "throttle body" but ours is a little different than a single-throttle M54 type deal...
TIA, nekky |

My P3cars gauge is reading that the throttle is at 5% even at idle. Does this sound weird? Could the butterflies be stuck open slightly, causing the shitty idle, almost dying when the revs come down and the dead/not dead/dead/not dead feeling I get in the gas pedal? This may all sound crazy, but I've basically given up on getting the car to run properly this year. |

As much as I wish it was this simple, I doubt it. I don't beat on the car a ton because I still don't feel 100% confident that it's up to snuff. The code hasn't come back since I replaced my O2 Sensor.

There's no idle bypass on the S54. 75% throttle at WOT is also normal

I really need to figure out why it's running shitty. Anyone else have a "dead" feeling gas pedal? And the dead feeling fluctuates as well. Sometimes it feels like stock, sometimes it feels like the first inch or two, I have nothing. And then it bogs if you just lightly press it. So confused!!! |

I read that the most common one with a fault is the one located under the intake manifold, which is a bitch to get to on NA cars. Luckily, with the ESS manifold, one needn't worry; it's easy to change. I took the one at the front of the throttle bodies off my dad's coupe and swapped it with the one located under the manifold on my roadster, and it *seemed* to make a bit of a difference, but I think that was just the placebo effect. Still runs like crap. That was well over a month ago too, and my dad's car is running fine as well. Obviously wasn't bad.
I actually thought there were *three* TPS. Isn't there some sort of sensor actually *at* the gas pedal??? |

After it stops the revving, it will idle *rock solid* for the next few minutes, and even while driving, it will run and drive near-perfect. After it warms up some more, it will now proceed to bog if I push the clutch in and let the revs drop. Sometimes it will die. In addition, after a few minutes more, still running well while driving, it will now *idle* shitty too. It feels like a lumpy idle and that it's missing or something. The car has a brand new VANOS system as well as spark plugs. I know there are a lot more things I could do but I've checked quite a few things already and I'm not an expert. It's getting late in the year so I doubt I'll figure it out this season lol. Any input? Thanks in advance! |

Didn't you drive this back from Ontario or Quebec?? What have you done to the motor since then, Vanos, plugs what else? The erratic idle sounds like its in "limp mode" but if you can baby it to the point that it will settle into idle and drive it probably isn't that. Have you checked the connections on all the parts you took off and replaced during the Vanos change.

Next step is to make sure all the connections are good with the VANOS.. have any specific suggestions?? My father thinks it could be the solenoid pack. |

Are you sure all the coil packs are seated properly? So many things could have become dislodged working around under the bonnet, retrace the steps you took doing the work and eliminate those things as the problem.

Have you checked the Vanos adaptations?
I had similar issues and it turned out the mechanic that replaced my Vanos bolts had the cam timing way off.
