2003 alero 4cyl. 2.2l throwing a #1 misfire code

My 2003 alero 4cyl. 2.2l throwing a #1 misfire code. I've read about other such problems and people have changed there plugs and the houseing unit and still didn't change the problem. Then I've also read that people have said that if after changing the above mentioned parts it still occurs it could be the MAP hose or MAP sensor. Ok great, but where is this hose and sensor located? The Haynes book is no help becaus eit's more about the 6cyl. rather then the 4 cyl. and where it says stuff should be is not where it is.

TRY MOVING THE WIRE HARNESS TO THE INJECTOR WHILE THE ENGINE IS RUNNING, EVEN STRETCHING IT A LITTLE. THE WIRES CAN BREAK INSIDE THE COVERING AT THE PLUG.

TRY SWAPPING THE #1 PLUG WITH ANOTHER ONE TO SEE IF THE MISFIRE GOES TO THAT HOLE. SAME GOES FOR THE INJECTOR.

LOOK CAREFULLY AT THE COIL HOUSING TO SEE IF THERE ARE ANY CRACKS ALONG THE AREAS CONNECTED TO THE SPARK PLUG. USE A SPARK TESTER ON THE COIL PACK TO CHECK FOR SPARK, THIS MAY REQUIRE THE USE OF SPECIAL PLUG WIRES.

IF NECESSARY DO A COMPRESSION TEST ON THE ENGINE.

The map sensor is located on the throttle body. you have to take off the air intake hose clamps.

Cylinders 1 and 3 misfiring on 2.4 Liter 97 chevy malibu


code p 0300 is random/ multiple cylinders ----misfires detected ===causes ---spark plugs ---HT lead/s---injector/s---ignition coil/s---low compression---wiring
he has changed a lot for nothing
a 5 year old engine can have a lot wrong with it --so new out of a crate is no guarantee
most misfires are from injector problems
it could be a loose valve seat insert so have a compression test done if moving the injectors to new locations doesn't move the misfire

2.4 liter OHC coil housings have this as a common failure. Thery arc over internally to another cylinder and cause the misfire.

Replace the coil packs.
Your issue is NOT the converter, or you would have a P0420/P0430 code

Confused?


it is probably throwing a "cylinder misfire" code which is an indicator that the fuel didnt burn out of that cylinder, just change spark plugs, that is about the cheapest code it could throw, dont be alarmed.
