i have a 88 toyota pickup that i just did a head gasket on. after days of with it i finally got it running, but it lacks a lot of power and im pretty sure it ignition timing. ive redone the timing about 5 times and still lacks power but each time i do it, it gets better. ive been using a chilton manuel and still cant figure it out if some could please help me out thanks

 

you're shorting the E1 and TE1 terminals in the diagnostic connector behind the battery, correct? and when you do that, the idle speed changes, correct?

 

i figured everthing with the timing today now i got another problem im getting a c.e.l code 25 and thats because the o2 sensor is not plugged in but i cant find a connector any were that would fit the o2 sensor the truck ran great before i swapped motors with an 86 but i put the 88 wiring harness and efi from the 88 motor, and that motor never had a o2 sensor and it ran great lots of power. i want to know how that motor could have ran with out a o2 sensor and this motor is running like because it has one, and yes the 88 motor should have one but it doesnt. so any help on the would be great thanks.

 

the o2 on an 88 should be under the cab, in front of the catalytic converter.
did you look there?

 

found it haha toyota likes to hide things i see well thanks for all the help now im getting code 25 should i swap and o2 sensors with the 86 and see if it helps or buy a new, im flat broke i spent all my money trying to get this thing running again so let me know what you guys think thanks.
