got in my car started it was running bad. check engine light came on. took to advanced and had codes ran. this is what i got:

p0301=cylinder 1 misfire
p0303=cylinder 3 misfire
p1316 manufacture control ignition system or misfire
p1111 manufacture control fuel air metering

can anyone help on this issue?

 

Use Search for each of them. Any P1 code is maker-specific so you MUST look such codes up for the right maker. Currently you have the wrong meanings.

Anf for goodness sake put your car details (year, engine etc) in your profile!!

 

... if not in your signature, or garage, at least in your original post.

 

They mean get ready to reach really deep!

 

ok sorry the car is a 03 stype v-8 with 119k on it. the first two are coil packs i am assuming and the p1111 is a vac leak according to what i have read. i also have seen where running these cars threw a car wash can cause moisture on the engine which will cause the code to be thrown. its the p1316 that i dont know. but further more i didnt know if they were all related.

I don't have my JTIS with me to check your DTC codes, but the P1111 is not a vac leak.

The others may be misfire due to bad coil packs, and if so... easy to replace. On similar failures, oil leaked into the plug well and killed the coil.

When/If someone confirms the two codes for you, and if they're misfiring, be sure to keep an eye out for fluid source.

 

P0301 and P0303 refer to misfires

If, on the first trip, the misfire is severe enough to cause excess exhaust emission, the individual cylinder DTC plus DTC P1316 will be logged. The CHECK ENGINE MIL
will not be activated. If the fault reoccurs on the second trip, the individual cylinder DTC plus DTC P1316 will be flagged, and the CHECK ENGINE MIL will be activated.

If DTC P1111 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE BEEN COMPLETED.

Sorry that is all I can find.

I found this on the JTIS

DTC-P1316

FAULT DESCRIPTION - Misfire excess emission
NOTE: This DTC will flag only
when accompanied by an
individual cylinder misfire DTC:
P0300 – P0308

POSSIBLE CAUSES - Cylinder compression low
Worn camshaft / broken valve spring(s)
Fuel delivery pressure (low / high)
Fuel injector(s) restricted / leaking
Fuel injector(s) continuously open
Fuel contamination
Fuel injector circuit fault(s)
(Injector DTCs also flagged)
Spark plug failure / fouled / incorrect gap
ECM to ignition coil primary circuit fault
(Cylinder misfire detected DTC also
flagged)
Ignition coil failure

 

This is all I found on P1111

If DTC P1111 is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE BEEN COMPLETED.
