Timing problem
 

I recently checked the timing on my supra because it will not idle below 1000. it is at about 30 degrees instead of 10 :-0 My only problem is that i don't know how to lower it on this car... i can't find anything even in my hanes manual about how to do this. btw it is an 89 toyota supra turbo.

remember that on the 7m gte engine you must use the #6 wire not the #1 wire. for anything else i would always consult the TSRM
