Hello everyone...I am at wits end with this little car and if I had hair I would pull it out...lol
1996 Toyota Corolla
1.6L DOHC EFI
Standard transmission.
I was driving to work the other day and the engine light come on/flashing and it starting skipping/shuttering really bad. I drove it back to the house, and had the codes pulled from the computer.
The following codes appeared:
P0300 - Random/Multiple Misfire Detected
P0302 - Cylinder 1 Misfire detected
P0303 - Cylinder 2 Misfire detected
P0305 - Cylinder 3 Misfire detected
P0305 - Cylinder 4 Misfire detected
P0105 - Manifold Absolute Pressure or Barometric Pressure Circuit (MAP)
P0120 - Throttle/Pedal position Sensor A Circuit
I have changed so far the Throttle Sensor and the MAP Sensor to no avail.
All plugs look good and all cylinders are getting spark, and all fuel injectors have been cleaned in an ultrasonic bath and seems to be working (I pull the connector off and the engine dies a bit)
It idles at around 1750rpm and it shutters badly like the engine is out of timing through all phases of driving.
So I am pretty much stuck right now.
The computer reader gives the following parameters at idle
MAP (Hg) 7.4
Ign Adv 36.0
ST FTRM1 % 0.0
LT FTRM1 % -1.6^
Fuel Sys Open
O2S11 - .140
O2S12 - .060
