Why is my 84 chevy truck stuck in closed loop

I'm working on a 1984 Chevy C10 with a 305. The vehicle is stuck in closed loop and the scan tool shows the knock sensor is retarding the timing from 0 to 45 degrees. There is no knock sensor on this vehicle.

SOURCE: knock sensor

The knock sensors are located in the rocker valley underneath the intake manifold. GEt a hynes manual to assist you in replacing them. There is acertain tightening sequence when taking the manifold on and off. It is made of a composite plastic so use care and do not over tighten.

Under intake manifold on top of block,you need to remove intake to access sensors there are two of them you can't miss them when intake is off. After replacing sensors you need a new intake gasket.

84 chevy running rough

Check the choke when cold. When its hot take notice that its opened. Upon starting next time when its cold look at the choke and see if its closed fully. It should be. If not push the throttle all the way open and let it retract closed. The choke should close when the engine is cold. If it does not the vacuum break is shot which should be the rear one that controls the choke. Yours may be on the front since some are but very few are made on the front
