Sorry Scotty posted that up right after shower and right before bed. Was out tinkering with this thing about 3 hours after getting home from work and still haven't a clue as to what could be wrong..
Anyways here's what all I've done....
1.First after iniatially hearing a mysterious knock turned out to be a loose rocker..
1a. Removed valve cover and sure enough rocker on #3 was loose. retorqued it and knock eliminated..
2. Noticed miss in car after tightening rocker. Went to get scanned. Got a 0303. Checked wires and plugs. Found a bad plug.
2a. Replaced all plugs with OE iridiums..
3. Still noticed a miss so went ahead and bought a scanner and scanned. Got a Po303-Powertrain Cylinder 3 misfire..
3a. Swapped wires around again and no change.
3b. Replaced wires and no change.
3c. Swapped coil packs and no change.
3d. Bought new coil pack to be certain and no change. Used electrical grease on connections eventhough no corrosion was noticeable.
4. Rescanned and still getting a p0303-Powertrain Cylinder #3 misfire.
4a. Removed valve cover and rechecked rocker to check torque spec at 11lbs. Rechechecked spring. All looked good.
4b. Swapped fuel injectors in #1 and #3 to see if maybe bad injector. While doing this I noticed fluid on top of manifold with what seemed like a bit of antifreeze but not alot. Cleaned it up and cleaned injectors. Checked O rings. Good.
4c. Put everything back together. Checked for leaks and anything I could of left loose or broke and all looked good. Hooked up battery and turned on ignition (without starting car) to pressurize fuel lines and rechecked for leaks. All looked good.
4d. Checked oil level. Checked coolant . And fired her up. And absolutely no change. As if I hadn't even touched it. Rescanned and still a po303-Powertrain Cylinder 3 misfire..
HELP!!!
