ok well ive been getting this check engine light every once in a while. what happens is the car starts to run rough for a little like its missing, then suddenly the CE light comes on. it happens for like 20 minutes then starts to run normal again and i clear the codes and it doesnt come back until the next time it decides to run rough. i cant seemto figure it out. this is the code its throwing and the description. can anyone help me out? thank you


P0356 Ignition Coil F Primary/Secondary Circuit Malfunction

 

hmm, i'd pull your spark plug covers on the valve covers and check all you're Ignition COPs. Make sure they are all making solid connection on the spark plugs. On my old mach i pushed one on and it didnt go all the way onto the plug, and ran rough like you describe. Since it is saying Ignition coil F that may denotethe problem is on your #6 cylinder- make sure to check that one really well.

 

thank you. which cylinder would be #6?

 

I would start with the COP's actually start with cylinder 6. code 351 Thur 362 the coil codes and I believe 356 is Cylinder 6. Make sure they are all good and tight and the bolts are tight

 

Duh! Machmon you beat me to it

 

Also here is a full description of the code/desription/possible causes:
P0351 Through P0360 - : Each ignition primary : * Open or short in :
: Ignition Coil A : circuit is : Ignition START/RUN :
: through J Primary/ : continuously : circuit :
: Secondary Circuit: monitored. The test : * Open coil driver :
: Malfunction : fails when the PCM: circuit in harness :
: : does not receive a : * Coil driver circuit :
:: valid IDM pulse signal: shorted to ground :
:: from the ignition : * Damaged coil :
: : module (integrated in : * Damaged PCM :
: : PCM). : * Coil driver circuit :
: : shorted to PWR

 

Driver side second one back

Doh... sorry lol.

Cylinder #6 should he the second from the front on the driver side.

4 8
3 7
2 6
1 5

Thats how it is on GTs at least- im guessing it should be the same for machs.

 

ok ill pull it tomorrow. do u think it could be serious or maybe just a loose coil pack or bad coil? if so, it can be simple, or can i have something expensive to fix?
