I picked up the 2004 in my sig 2 days ago. the PO said his mechanic cheeked it out and it needs an engine. it has a p0304 and sometimes a p0316.............here is what I know and have done....
I have and been driving it around for 2 days . Before I drove it away from the guys house 2 days ago I cleared the codes and swapped out the #4 plug and swapped the 4 and 5 wires. The cel came on within an hour of driving. I have cleared the codes 4 times. This might be my imagination but seems to be worse right after clearing the codes. The Cel has flashed about 3 times for about 10 seconds. It only does it while idling. The CEL has not flashed while driving. I seafoamed the truck, doing the 1/3,1/3,1/3 way. I did get a p0301 right after the seafoam but I cleared it and it has not cone back. Truck runs good beside this occasional issue. I have plugs/wires on order. I eventually will do compression test. I talked to a mechanic friend today and he thought it could be the injector. The codes I keep getting are the p0304 and sometimes p0316. Another weird thing is sometimes the cel goes out but the code is still there. All ideas are welcome.
P.S. I put my stethoscope on the cam sensor and it sounds perfect. I do have a squeak that I am calming down by spraying wd40 on the pulley bearings.
all help would be appreciated!
