My 2003 ford mustang is sputtering and the check engine light is blinking no code


You can get a free scan from Autozone, Oreilys, or Advance auto parts. This should indicate a problem. If the standard test scanner does not verify a problem, the Dealers have more advanced scanners which can capture intermittent problems.

There are so many possibilities that you need more tests to find the problem. Offhand, if this is a V6 engine, there were problems with intake Manifold runners and sandwich gaskets for 2 piece intake manifolds.

Stuck manifold runners could provide lousy low rpm performance and perfect high rpm performance just like you describe whether a V6 or V8. The 2 piece intakes were used on V6 engines and once you get above midrange in Rpm, it could run acceptably at higher Rpm.

Where is the air intake


Your air intake is the big aluminum piece at the back side of your motor parallel to your valve cover. If you look at your motor, the exhaust manifold is on the front of the motor, and the air intake manifold is on the back of the motor near the firewall. Hope this helps

I have a 1973 ford mustang grande and the engine in it is not the original engine. I was told it was the original 302 but i know its not. I looked up the model/serial number right behind the carbeurator on...


That number is not on the block - it is on the intake manifold. It is also not a model or serial number. That number is the casting number for an intake manifold. Yes, it is an intake manifold for a 302 cid engine.

Coolant leaking in and around the intake manifold as well as the under carriage of that same part I think. Outake? I know that the part that attaches to the manifold appears to be metal but the manifold...


The plastic piece is the upper intake manifold. The metal part is the lower intake manifold. Sometimes the gaskets go bad between the upper and lower intake manifolds. But usually the upper intake manifold is cracked and needs replaced.

Where is the temperature sensor located on a 1978 Cadillac fleetwood with 425 c.i. and carburated intake?


It should be the same as the other GM engines, Between the first 2 cylinders on the driver's side of the engine. It's somewhat hidden by the exhaust manifold. Hope this helps.

Intake manifold gasket / replace


3.8L Engine

NOTE The 3.8L (VIN K) non-supercharged engine uses a two-piece intake manifold consisting of an upper air plenum which mounts the throttle body and a lower intake manifold assembly which houses the fuel injectors. The 3.8L (VIN 1) supercharged engine uses a similar lower intake manifold. The supercharger serves as the upper manifold.
Lower Manifold

NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold. Remove the upper intake manifold to service the lower intake.
The 3.8L (VIN 1) supercharged engine uses a manifold similar to the 3.8L (VIN K), but the supercharger serves as the upper manifold.
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Remove the upper intake manifold using the procedure above.
  4. Remove the EGR outlet pipe from the intake manifold.
  5. Detach the engine coolant temperature sensor wiring harness from the sensor.
  6. Remove the lower intake manifold bolts and carefully lift off the manifold.

To install:

  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces and between the lower manifold and the cylinder heads..
  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Apply thread-locking compound to the bolt threads. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 11 ft. lbs. (15 Nm). Follow the toque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

Upper Intake Manifold (Plenum)
  1. Disconnect the negative battery cable.
  2. On 3.8L (VIN 1) engines, remove the supercharger assembly. Please see the procedure in this section.
  3. Tag for identification, then remove the right side spark plug wires.
  4. Disconnect the ignition wires from the fuel rail.
  5. Remove the fuel rail. Please see Section 5.
  6. Remove the cable bracket from the intake manifold.
  7. Remove the throttle body.


NOTE Two bolts which fasten the lower intake manifold to the cylinder head are accessible are accessible only after the upper intake manifold is removed. These bolts are located in the right front and left rear corners of the lower intake manifold.
  1. Remove the upper intake manifold bolts and carefully lift the upper intake manifold from the engine.

  1. Clean all parts well with degreaser, especially the gasket seal surfaces on the upper and lower manifold pieces.
  2. Install new gaskets to the cylinder heads and new seals to the engine block. Carefully lower the manifold into place. Make sure to install the two hidden bolts in the lower intake manifold. Hand start all bolts, then torque evenly to 89 inch lbs. (10 Nm). Follow the torque sequence, starting in the center, then working outwards in a circle.
  3. Install the remaining components in the reverse order of the removal process.

Engine idles with choke on only


You either have cracked intake boots/ manifolds or the idle circuit in the carb is plugged with stuff. Spray some brake cleaner around the intake manifolds (air box in place) and see if the idle picks up. If nothing happens pull the air box, fire it up and put your hand over the carb(s) to try to **** it through....rev it up...cover carb with hand...repeat. Next you're removing carbs and cleaning
