SOURCE: reads codes of po300,po302,po303,po305

Hi these are mis-fire codes ,
P0300 is a general mis-fire detected code the others relate to specific cylinders,
P0302 is cylinder 2 misfire
P0303................3........
p0305..................5........
I would check your spark plugs first if Ok you need to make sure the coils are working ok for this you need an osciloscope to check output voltage if your not sure then take to a qualified mechanic with Cadilac experience it could be caused by an air leak,bad ECT sensor or even Mass air flow sensor ,codes only tell you the result not the cause

SOURCE: 2002 ford escort zx2 camshaft sensor fit a 99 zx2?

Yes, All the years of the ZX2 utilize the same engine. 1998-2003 are all the same except for ECU programing and the MAF wiring. You should not have a problem.

Zeevert was right about all but one thing. Cylinder two is the rear middle cylinder on a V6 or the second one from the passenger side on a 4 cylinder.

po303 is cylinder 3 misfire, po304 is cylinder 4 misfire, po305 is 5 cylinder misfire. this means it could be bad plugs, wires. or coils that are bad. change plugs and see how it is running.

SOURCE: 2003 freeland code p1319 , misfire code

OBDII those codes generally mean misfire.

P0300 multiple missfire
P0301 missfire cyl 1
P0302 missifre cyl 2
ect.

Ensure you have the proper spark plugs. Check the coil boots/wires, look for burn marks. Anything beyond that you may have to take it back to the shop.
You are misfiring on all 4 cylinders and it is not spark plugs. Those misfires if not addressed can cause serious engine and/or cat converter damage. There are lots of things that could be causing it and most of them need to be checked out at a shop - unless you want to invest several thousand dollars in the appropriate equipment and training.

there is nothing wrong with the timing chain position . Just a series of sensors that have gone outside the set parameters so if you check and change each one you will clear the faults.

Po302 po303 po316 code


The Codes 302 & 303 are cylinder misfire codes,google them

Spark Plugs have nothing to do with misfires,it would be rare in
a life time if one ever failed to fire

Forget the 316 just misfires on start up

A repair shop would be your best choice without knowledge,
