Disconnecting the TPS allows the timing and idle to be set properly. When it is connected again, the ECU will take into the account the position of the throttle plate.
The reason I asked was because when I disconnected the TPS, the timing marks advanced past the limits of the movable rotor asembly. When I hooked up the TPS, the marks moved within range of where I could align the marks, so I left the TPS connected while setting the timing. Was this wrong? If so, what did I do wrong, and why did the timing marks move out of range when the TPS was disconnected?
i also did this same thing and it happened to myself. and my rpms went up to 1900 rpms. so i just plugged the tps back in and the timing was only off by about 4 degrees. :S
oh god. ok go read my post on the definitive guide on how to adjust the timing. then come back. you can't miss my post, its the first post in this forum board. you guys aren't even doing it properly.
i did it exactly how it said on the post...after disconnecting the tps it reved up to 2000 rpm....which isn't idle...and the timing was WAY off....so i tried hooking the tps back up and well....look at that....i could find the timing marks easily
okay FIRST:
REV TO 3000 RPM THREE TIMES WITH YOUR TPS DISCONNECTED AND LET IDLE SETTLE
ADJUST IDLE WITH IDLE SCREW
THEN ADJUST TIMING
whatever, your timing is WRONG and so is your idle. so did the timing marks stay in one place with the TPS back on, or did it JUMP everywhere when using your timing light?
i used the all knowing "alldata" that we have at my workplace and it doesn't say anything about reving it up or even unplugging the fan...the instruction on that software was tolet it warm up...disconnect tps and check the timing....so that's how i did it the first time...then i seen the way it was posted on here and it still didn't work with the tps disconnected....so im confused and puzzled...:S
