I'm going to despair...

Hi!

So I have the following problems with my 93 3.6 automatic, equal to 2 in number.

1: Pulsing acceleration. Yeah, I know, should be the Lambda probe. But it's not! Right now, she's gone. Besides, the only good 20000km is old. The BC does not indicate any change in the current structure.
Furthermore, I have exchanged the following: 2 new tap sensors, 2 other distributors, other air mass meters, all new temperature sensors. If you have a TIP, please write. I'm really pissed off.

2:: As some know, I'm driving around with a wrong gear control unit (from 4.2). Now there are 3 different ECUs. I need the three. (from 92). So, who has one, please report.
So, and now Alex Kölske was so friendly and has got me a transmission control unit of the 2. AYU to 92). The key letter of the gearbox is the same, so pure with it. Started, driven, no switching operations, just like with the very old ECU. ==References== Gang (or 3.).
So even once the engine control unit that fits to the transmission control unit, with in. My baby didn't even jump!
So, everything back out and put it on the old stand.

Here we go. Since then, the S-E-M switch no longer jumps to E when I start and all switching attempts at the thing to choose another program level are in vain. Nothing is happening, no more changes in driving. Not even on M! Everything's E or something. What a mess! What can that be?
Measured at the switch, no plus pulse comes to snap back when starting, mass is due. Please give me a hint what this is again. Lock them all up.
Oh, yes, if he's on E before starting, nothing will happen. No reaction while moving the switch. Trying others doesn't work either.

PS.: If you have a transmission control unit with the characteristic letter 441 927 156 AC or ....R, be so gracious and give it to me.
