out of all this problems posted for this particular problem, will the check engine light and or safety mode be illuminated?

knocking sound is bad-probably rod bearing going out on the crankshaft-time for a new car-Denny

If it has the 3800 engine, usually the issue with this engine is at some time, the upper intake manifold (plenum) developed an internal coolant leak, from the plastic housing just under the throttle body, from the EGR tube that flows in to upper plenum. This causes the coolant to seep into the lower intake manifold ports and into the engine cylinder, on top of the piston, and when the engine turns over, sometimes this coolant causes this concern. If at any time you started your engine, and it stopped turning (cranking) over for a split second and then cranked over to start, this could cause the connecting rod to bend slightly causing the internal engine knock. Was your coolant/antifreeze ever low?? Is your engine oil have a milky color?

The shift solenoids are located in the sidecover if the transmission. To get that cover off, the engine/trans/frame assembly needs to be lowered on the drivers side. To do that, special support fixtures must be used. Very big job.Transmission shift solenoid location picture

Here is a diagram of the firing order for you 3800 engine. Cylinders 1 and 4 are misfiring because the operate under the same "Coil Pack" and the coil pack has unfortunately gone bad. O'Reilly sells them for between $30-50 depending on the amount of warranty coverage you want. To replace, simply unscrew the screws that hold the coil pack in place. WAIT before unplugging the plug wires. Place the old coil pack and new coil pack next to each other, unplug one plug wire, then plug it to that same port on the new coil pack. then do the same for the other plug wire. Then screw your new coil pack in place, and start you car. should run fine!

If is factory you wont be able to unless you have a computer and a program to do that. If it wont go away just takeing the battery cable off, tehe dealer is going to have to do it
