Trust me, change the temp sensor first. It's on the front of the intake by the water neck. Two wires to it ( green & black I think) Change when the motor is cold, unplug it, unsrew it, put new one in. This sensor tells the computer if the motor is cold or warm so it can send the right mixture of fuel to the tbi. When it goes bad the computer thinks the motor is warm and will not richin the mixture up(like not having a choke) thats why it keeps stalling. Bad O2 will make your motor run ruff. ( like its not firing on all eight cyln) If you feel a miss its the O2. Good luck. TBI are great when you get to know them. P.S. Electric fuel pumps either work or they don't.
