It's the second write-up in post 38.

Which connector did you use to check the TPS? Square or flat?

 

Square. Tps voltage is at 4.66 and it is adjusted to 0.79.

 

Yes I did the ground test today. It was good. Stayed at. 01 the whole time I was shaking connectors.

 

For idle/driveability issues you need to be using the flat 3-wire connector, not the square 4-wire connector.

Flat is for the engine and square is for the auto trans.

 

Lol it figures!!
Question: If it is adjusted properly for the Trans/driveability, wouldn't it, or shouldn't it be correct for the idle as well.

Crusier, you are awsome by the way.

Technically correct. But in reality not.

There are 2 different "ribbons" in the Renix TPS. One ribbon can be good and the other bad. I took one apart and proved it to myself. One for the trans and one for the engine. They work opposite of each other!! At closed throttle the trans side is about 82% of the input voltage and the engine side is about 17% of the input voltage. Add up 82 and 17 and you get close to 100%. See the correlation? So, you need to adjust your TPS using the flat 3-wire connector to 17% of your input voltage.

In 1991 Chrysler changed fuel injection systems and made their TPS work like the trans side of the old TPS. Now, only one ribbon for both functions.

 

Ok, tell me if I'm trackin.

On the flat plug my output should be .8? At 17% of my input voltage.
On the square plug I should be closer to 4volts.

 

4.66 X .17=.79
4.66 X .82=3.82

Concentrate on getting the engine side (flat) correct. So between B and C on the flat connector you should see .79 volts.

 

I'll give it a shot tomorrow.

I think I will pull my plugs again and see if there are any signs of the cylinder that is missing.

 

Wiggle the connectors on the injectors, too.
