the PO300 code is for a random misfire in the engine, PO332 is for the knock sensor and PO756 is for the transmission not shifting or low vacuum.
I think if you fix the random misfire the rest will correct itself or in other words you need to replace the spark plugs and check the disturber cap for damage or carbon cracks and replace the rotor and you might be in business.
Start vehicle put trans in neutral with foot on service brakes if that doesn't work try disconnecting the TCCM under the right side of the dash if this is a push button type if that doesn't work you will need to have futher diag done could be codes set or a stuck acuator
Mulitiple cylinder miss fire,May be the coil boots and plugs,will fix your problem,and,or fuel injection cleaner with a couple of bottles of HEET,a water dryer to put in the fuel tank.
Yes they could a PO300 is a generic misfire code. PO301 would be cylinder number 1 so on and so forth. check the resistance of your plug wires they should be approx. 7000 ohms per foot. it could also be a coil over plug. primary resistance of the cops should be 1-3 ohms. but since this is a misfire it would be your secondary. which should be between 20000-30000 ohms. hope I helped you out. Happy Motoring!
PO229 indicates tps circut inttermitent.
Po300 303 and 304 indicate missfires on cyl 3 and 4.. Was the fuel filter primed before starting the engine? If not ,remove and reinstall filter. Then prime filter with pump that is on fuel filter adapter. Once this is done restart and verify o/k
I have already done this and still the same problem.
