Silly Questions

in my quest for knowledge, does anyone happen to know what this switch is and how it works on the 700r4/4l60?


NonGrounded Governor Lock-up delay switch

Good morning gents. Im in the middle of putting my engine back in. I have a question. Im trying to time my engine and i know my timing is correct, firing order and plug wires correct. I cant get it to idle and i have alot of little back firing. You can hear the intak going crack......crack.......crack..........crack....

My question is my TPS sensor is only puttin about 2.4 volts with WOT. There is code 22 from the ecm. Can the faulty TPS cause all these idle issues.

Im also gettimg a knock sensor code 43, but i havent looked at it yet.

Please advise

ok so I got it to Idle after I replaced the TPS. I also adjusted the valves. The Code 43 for the knock sensor is gone. For some odd ball reason the Code 22 for the TPS low voltage is still there.

Is there and adjustment to the TPS. It is not the type with slotted screw holes. looks to me like no adjustment. Anyone have any recommendations?

Well after a couple of hours of tracing, I finally figured it out. I had the Knock Sensor and TPS wires crossed. Didn't realize until I got back to the ECM under the seat. Swapped the Dark Blues and BOOM, no more check engine.
