its to keep the antifreeze in the intake longer so the thermostat will open, at least that's my thinking

Thanks.

Got this thing all back together and for the life of me I can't figure out where the hell this plug goes? I have had one of my friends look as well and he can't seem to find anything either. Anyone got a clue what it might go to?

it goes with the other end of it

oil sending unit.

it should be almost under the edge of the distributor. well as long as you put the adapter back in the port in the block behind the intake

trucks don't have fetzer valves.

Only one way to know for sure. Place your lips around it and have your buddy crank over the engine. Suck hard to remove any obstructions in the hose and to start the fluids flowing. Use your taste buds to determine what's coming out. Don't swallow.

Thanks once again. I was hoping this plug was my issue because I still can't get the truck to start and stay running. If I give it gas it will start and run until I let off the gas. When it is running it is running super rough (shaking the vehicle rough) and I have black smoke coming out the exhaust. I have checked everything I know to check at this point. Doesn't sound like that is going to fix my issue.

sounds like the map sensor vacuum hose is unhooked or plugged at the throttle body.
or a ground is loose or wires pinched that have an injector hung open.


the map sensor is that square box in the upper left of your picture just above the egr valve that is missing the vacuum hose.

are you sure you have the firing order right?

hey I just saw I was right here. wow. good guess

I was wondering about the plug wires being out of order.

ive been dealing with a bunch of cars the last week that a nationwide gas station (its in a supermarket parking lot) had a dumbass tanker driver roll in and dump the whole tanker into the unleaded tank.

on Saturday night, right before a 58 degree sunday that everyone knew Monday was going to be 0 degrees. everyone in a place with much rural areas is moving on a day like that, town was crazy.


yeah its costing them tons of money in rental cars and repairs.

follow the #1 wire to the dist and its 1 8 4 3 6 5 7 2.

7th grade shop teacher made sure I would never forget that

Firing order is on top of the manifold. I have double and triple checked. All is good.
