    I need some help here I have a 1989 dodge d150le with a 318 tbi I put headers and a cam in it as well as deleted the factory smog pump having issues with truck being boggie on bottom end and pretty sure its vacuum related I need to know what the vacuum sylonode do and if they can be deleted they are normally mounted on passenger side valve cover.

    New issues - always, always, always look at the last thing you did before you start changing more stuff. Was the cam degreed?

      But was it degreed on install? I may be mistaken but I seriously doubt any 318 tbi has a computer controlling your camshaft. If it does, you have an extremely exotic setup and I wouldn't expect to see any of the vacuum sensors and the like in your original question still in the engine compartment. That is a chain driven camshaft and chain driven camshafts should be degreed on install to ensure the proper valve timing. Many have done the dot-to-dot alignment with the crankshaft/camshaft gears and had no issue, others have had problems with mismarked gears and such and that won't be found without degreeing the camshaft.

        Computer controlled timing. Do not confuse that with computer controlled cam timing. My 89 - 360 still has a plan old timing chain setup.

        What did you set your initial timing at?

        Does it matter on a 89? By 93 the computer just moves timing it to were needed. But then the 93 has a crank position sensor.

        My 88 has them on the pass side if it helps. The FSM covers their purpose.

        Well back to the original vacuum solenoid removal. I have not gotten that far into reinstalling the 89's EFI. I know it will not get installed unless needed and if it has a no purpose for being there it will not be.

        I did that when it got stuck in the 82. If the timing cover has the fuel pump access. Just remove the plate and install a pump. The esentric is all ready there

        Yes it does matter.

        So the computer does not take total control of timing and adjust to engine demands?

          I may be wrong about 89, I can't remember for sure if you set the initial with a timing light. The computer will handle all the advance though. The 93 dist is zeroed with a scan tool. The computer handles all advance.
          I believe it matters what type of pickup the dist in the 89 has, a magnetic pickup or a hall effect.
