ok what would make my 89 740 GL run rich? besides..
TPS
temp sensor
O2 sensor
timing

i dont want to have to buy new sensors and find out they dont fix the problem, if at all possible.

i checked the ignition codes and all i get is a 1-1-1, which would mean that the sensors are good, am i right?

also the timing is on when i use a timing light, but could it be off at the cam? i dont have the plastic cover to line up the marks :( i'm thinking that i could be a tooth off on the cam because i had replaced the timing belt not too long ago.

thanks in advace for all your help
