I just had my intake manifold gaskets, intake plenum gasket, thermostat bypass pipe, radiator fluid, and thermostat all replaced. Now I am having my check engine light come on with a code of p0106. When I reset the code it comes back along with the check engine light. It runs very good and has lots off power. The only issue is that when the code first appeared it was under heavy acceleration. The car jerked very hard three times and the check engine light came on. Now after resetting the code and driving slow the check engine light and code always come back. What is wrong?
2008 Grand Prix . High beams work but running lights won't come on. Fuses are good , bulbs seem good . If one bulb is bad will this cause both not to work? Or is there something else to look for?

Leaking coolant in 3 locations upper intake manifold(2) and timing gasket or valve i believe. Is it cheaper to fix these issues if under $800 or buying a used engine i know that shouldn't cost more than 1200
At first it would click when i turned the wheel to the right side an someone told me it might be your axel. Then check it the boot is torn.

The headlights will turn on and off by themselves when the car is just sitting. Nobody will be in the car and it won't be running. It seems to happen at random times. This is very persistent and kills the battery almost daily.
Ticking type noise in the motor at high acceleration
Intake manifold or head gasket -- is it possible overheating is caused by one thing and oil in coolant another?
I noticed my driver side head light extremely hot and when I touched the passenger side, it was not hot at all. My car had ran out of gas and when I added gas, it wouldn't start. It turned over, but didn't fire. I thought it was my ignition moduel switch again, but turned out to be the electric ignition fuse. Repalced it and it started completely, but is running terrible. It's as if something is fouling out. My check ingine light was on and at times flashed quite a bit. I know that means a misfire n to pull over and get a tow, but it didn't seem lime it was going to die. When I opened the hood while it was running, the engine shakes more then usual and it sounds like there's a blower on under the hood, but I had all the fans turned off. The car was also starting to overheat. What could possibly be wrong with all this?
I had already driven 8 miles, parked my vehicle, resumed my journey after 15 minutes. During my drive, of less than 5 minutes, I experienced a slight hesitation from the engine, the engine light when on, 2 miles later the car stalled. The car would not start up again. The weather was sunny, dry, temperature 72F.
