Timing wire

[G Winter]

Can someone tell me where abouts the tan with black stripe wire is located that I need to unhook to set the timing on my 90 ?
Thanks in advance.

Mine is located next to the brake booster ..Just below the MAP sensor...their is a plastic juntion you take apart...pic if you need it.

Thanks JonM I found it . I just had no idea where to start looking. I wonder if mine has never been checked cause it looked like it was taped to the harness with original tape. I replaced intake gasket because of oil leak at the valley and had two bad injectors. The new injectors cured a surging problem in lower gears at low RPM. Also had a slight thump to the idle which is now gone. Two injectors were way down on ohmage.

Did you just replace the two injectors, or buy a new set? Did you have any of them flow tested, and their spray pattern checked?

Just curious

I just replaced two for the time being . Next spring I may replace the rest of them. This close to the end of the summer I couldn't see spending the money.
I do think I have bad spray patterns in some cause the idle isn't 100 % yet.
But have a big improvement over what it was before. Got rid of the bucking in lower gears and the jumpy throttle is gone. You know, just try to crack the throttle and is seems like it all of a sudden gets a burst, that is gone.

I am not sure why this has to be disconnected, I have read multiple places to remove it and also it is not mentioned in others writeups. Jon M do can you send me or post a pic?
