I have had this war w/a TB I got from a buddy. off an V8 to a V6
1. install idle at 1200 rpms.
remove clean iac.
2. install idle at 1100 rpms. (getting better)
remove replace gasket
3. install ran like sh1t.
remove and got jet chip II
4. install chip (no tb upgrade)
RAN GOOD!!!
5. install V-8 TB and less low end TQ but O.K.
started this a.m. to a (the) little yellow
light.
6. reset computor and planning burial services
for a TB
Any ideas? (for the light not funeral)

I am wondering what code you are getting when your light comes on. It is probably your MAP sensor freaking out. Also, are the TB's from the same year? You may just need to change the throttle position sensor from your V6 TB to the V8 TB. I have noticed that when changing electrical parts from one year to the other that it can cause the PCM to read errors. In the software industry we like to call this "Keycodes" or "Product Registration #'s". There may be one minor difference in the signal that the throttle position sensor is sending to the PCM. It should interchange just fine if I remember correctly.
Also, the V8 throttle body flows too much air for the stock V6. If you have lost low end, then this proves my point. Get a Dremel tool and some polishing bits and shine up the inside of your V6 TB. This will give you what you are looking for.
Good luck!

The TPS, MAP, and IAC are the same from V6 to V8. No differences in the reference voltages and initial settings.
Does sound like a year/model issue though. If the TB came from an older (95 or older) model, they have an EGR port (and two small holes in the bores). It will work on a newer model, but you would have to cover up the port.
As for flowing too much air, the 48mm is actually the perfect size for the V6. Dyno, street, and track tested.
Here's a little trick:
Drill out the two brass inserts on the TPS sensor and then reinstall it. (You'll need a Digital Volt Meter for this next step.) Set the Key ON/Engine OFF voltage to .68-.70 volts. Reset the PCM and start the engine (without stepping on the pedal at all). You're throttle response will be much better from idle to off-idle. (This applies to the V8's as well.)
On the "shining up the TB bores"...do NOT do this unless you know what you're doing. One slip and you can kiss your TB goodbye. There's a step in the bores (Torque Step) that can be removed but if you enlarge the bores in all the way down, you'll need to replace the throttle plates with larger ones to match. Also, polishing up the bores does absolutely nothing...Flometrics already proved this one on their simulation and flowbench testing.

OK so I am 100% wrong then. Thanks Bernd for being so smart. By the way, I haven't heard back from you on the price of the Mopar PCM for a '97 5.2 auto 2wd fed Dakota.
Let me know!

what happens if the pins are drilled on a v6. I took the V8 off. i also have the chip (jet II)
