fuel cut, check engine light with a loud valve tap!!

[mazdaspeedson]

i had a similar problem with my protege with what felt like fuel cut but it was actually the engine sputtering and what it was, was the manifold bolts holding the turbo and manifold together had loosened and there was a huge seperation causing loud turbo noises and compressor surge the super sequential sound the problem worsened because they just kept backing out, also again i had what i thought was a similar problem but it happened to be a bad coil pack which should throw a check engine light to notify you which pack to change because your car has 2 of them


ps if your checkin your manifold yourself it isnt always just looking under the hood the heat sheild has to be removed but not just that my seperation was in the back side so just looking in the front didnt work you can take a mirror kinda like the ones dentists use they sell them at your local parts store and look in the back a sure sign will be easily seen seperation or harder to see carbon build up (black) on the engine block or on the turbo


good luck

MSP protege problems..

Hi guys, I'm new here and I figured you guys could help me with problems I'm having with my speed. First in the morning, when I start the car it will Rev up to 2000 then drop down to 0 and shut the car down...Sometimes I have to start it twice before the car run proprely.

Second problem is that I have a check engine. The code is P2009, what does that indicate ? I read it up on the net but I have no clue what the description mean....(boom04) Can you guys help me with that ??


Third problem I'm having is, my HEATER doesn't work !! Again what can be the problem ??

1st problem sounds like you need to change your spark plugs...could be other things, but that is a problem I had and new plugs took care of it.

2nd problem...I dunno what that code is...i think it has something to do with the tumblers in your intake manifold...I might be wrong, but even if i am not I do not know how to fix that problem.

3rd problem...I also just had to fix my heater...check the wire cable and make sure it is attached to the heater door knob and that the metal clip is still holding the rubber around the wire tight to the white piece of plastic that it should be attached too. The heat only comes on if the heater door is held open by the cable...if the cable is not connected correctly you might get too much slack and it wont hold the door open. Or it might not be connected at all. (the wire is easily located by removing your glove box and looking under the dash on the passenger side of the car). It could also be a coolant issue.

P2009 - Intake Manifold Runner Control (IMRC) Solenoid Control Circuit Low Voltage

Very few threads on this...sounds like an electrical issue or a bad solenoid

CrashKelly, Thanks alot for the help. You were right in terms of the heater, a wire was disconnected. Now my heater works perfect. As for the problem in the morning, I'll go get me some spark plugs for sure. Any recommendations for spark plugs ??

By the way, what are the negative effects driving a car without a catalytic converter ??
