New to the group and I, too, have been the victim of this problem. I was thinking it was radiator leak due to losing coolant and side of radiator was "wet". More and more reading and researching and having pretty much the same symptoms.
- gurgling / waterfall at start up
- rough idle for a few seconds then settles down
- CEL p0306
- sometimes, car will run a little rough (but not all the time)
- does NOT overheat (yet)
took to a mechanic and I told him that its NOT the coil as I've already switched them around and changed plugs too. I've also told him the symptoms and possibility of the HG being bad and I asked him to do some pressure testing and such ... he came back to me and said, it's not my HG but it was the coil - and he was adamant that he's right... so I took the car back...
with that said, any San Diegans who can refer me to a mechanic that knows the problem on these trucks and has done the job?
thanks in advance.
