SOURCE: what two coolant lines connect to the throttle body on a 3.1 multi port engine

There are no coolant lines connected to the throttle body, just the two fuel line. The high pressure side and low pressure side (Return line) and I believe the lines don't even connect to the throttle body on a multi port engine, the lines go to the fuel rails to the injectors.
Good luck

SOURCE: 1993 toyota 4x4 idle problem

sounds like your throttle positioning sensor is not set right so i would undo the two phillips heads that hold it and turn it till the idle doesnt fluctuate should be turned most of the way to the front of the truck. Also check your idle screw that throttle body could be set different.

On a 84 porsche 944 where do the vacuum lines go to on the fuel rail 2 regulators. Where do they connect from regulators to where?


If it's not a turbo, the vacuum lines for the damper and regulator go to the vacuum nipple on the throttle body that is underneath the assembly and on the manifold side of the throttle plate. The other vacuum hose that is connected there is ported, on the non manifold side of the plate. If it has vacuum when the throttle is closed, it is on the manifold side. You'll need a vacuum tee to join them into one hose to connect to throttle body nipple.

Replaced egr valve and cleaned ports, giving same code.


When you say you cleaned the ports which ports did you clean.? These engines are very sensitive and do build up lots of carbon on the small egr vacuum ports. The focus here is usually the vacuum port inside the intake manifold that is behind the throttle body. Take the throttle body off and look inside you will see usually a big deposit of carbon where the port is to be. That needs cleaned. You also need to check the vacuum line that runs from the intake manifold over to the right strut tower. This goes to your boost sensor solenoid. Make sure that that line has good engine vacuum. If it does not clean that port as well. If that line is clogged I have seen the carbon get so bad that it clogs the boost sensor solenoid and the vacuum line after the solenoid. All of these ports need cleaned not just one.

I need a vacuum line diagram fo a 1996 Chevy Lumina, 3.1. One line that is not connected to anything, is located at the top of the engine.


Sorry I don't have the diagram, but I do have a diagram of the engine and component locations. Your vacuum system is fairly simple. You have a MAP sensor attached to the air cleaner. I have pasted a picture below. It has one electrical connector and one vacuum hose that goes to the intake manifold or the throttle body.
Behind the right headlight is your evap canister. This will have a hose or line running to the fuel tank. Then it will have another hose going to the purge valve. The purge valve should be close by and it has a connector plus another hose that goes to the intake manifold.
Then you have the PCV hose that goes from the PCV valve in the valve cover to the air cleaner or intake manifold. I think yours just has a hose from the air cleaner and the rest is internal.
There is one more vacuum hose, and that is the bog one that goes from the intake manifold (or throttle body--looks to me like there are a couple of vacuum ports on the back side of the throttle body, and there may be a "T" on one of the hoses) to the brake booster. It this one was off, the engine would not run, as the vacuum draw is large. Please let me know if you cannot figure it out from these instructions and provide a picture, if you can.

I have a 1987 s10. I need to figure out where the three vacuum line coming out of the transmission are supose to go. I bought the truck with just the vacuum lines hanging from underneith the truck.My 4...


The three lines hanging under the truck connect to a valve on top of the 4x4 transfer case, this is why the 4wd does not work. As for the throttle body lines there should be a diagram on the radiator support that explains that. You should have one large line that goes to the PCV valve, a small line going to the air cleaner, a small line connected to the MAP sensor and possibly another connected to a valve that controls the EGR valve. Your fifth line should connect to a port on the manifold that supplies vacuum to a tank that is the vacuum source for the HVAC control doors and the front axle engagement system. The axle engagement system is what the line hanging by the transmission under the truck is for.

  5. Disengage the wire harness connector from the injector.
  6. Disengage the wire harness connector from the WOT switch, ISA motor and TPS.
  7. Disconnect the fuel supply and return lines from the throttle body.
  8. Tag and disengage the vacuum hoses from the throttle body assembly.
  9. Disengage the potentiometer wire connector.
  10. Loosen throttle body retaining bolts and remove throttle body assembly from the intake manifold. To install:
  11. Clean the intake manifold and throttle body mating surfaces of old gasket material.
  12. Install a new gasket and the throttle body assembly. Tighten the mounting bolts to 16 ft. lbs. (21 Nm).
  13. Engage the potentiometer wire connector.

I am installing a Holley 2818 on my '65 327 and need help with routing the PCV lines. Which line goes to the PCV inlet on the carb? The rear block inlet or the one on the oil filler neck?


On the 2818 holley there is a calibrated elbow on drivers side of carb about centre of the main body.This connects to oil filler stand pipe in front of intake.Fresh air hose goes from air cleaner to back of block where road draft tube used to be before PCV came along.
The calibrated elbow serves as PCV metered orifice.Be sure flame arrester screen is inside of air cleaner on fresh air connection.

Lost vacuum at defrost & vent & floor control.


It does not hook to throttle body , it hooks to a vacumn port on the intake manifold. Follow hose from cruise control module to the tee-three-way connector on firewall. Over time the tee will fall apart and will leak One hose goes to the vacumn port, one to cruise module,one to ac contols.
