My 2000 Pontiac GrandAm Se was hesitating when the gas was pressed and after a few minutes of dragging and the stern wheel shaking/vibrating it would take off like a rocket. I was told that I needed a tune up and took it in for repairs after the tune up was done along with the coil and coil housing cover being replaced. When I went to pick up my car I tried to use the remote starter but it would half start and cut off the mechanic took a look at it and fixed it where it would stay started with the remote starter but said that the coil burned out and the engine light was on prior to the tune up an coil repkacement due to the remote starter(Is this possible? I've had the car for about 5yrs and the starter was put on by the dealership after purchase)

I would start by doing an oil change myself so you can examine the oil and look for water/antifreeze in it. You will be able to see it separate from the oil and you can smell the antifreeze. If there is then you have a leak between the water jacket and the heads somewhere. More than likely the LOWER intake gasket is leaking into the head. You said they replaced a gasket but was it the UPPER or LOWER? If it was the LOWER did they use RTV in the correct areas? Did they torque the intake bolts to the correct pressure and install the bolts correctly? I know you don't have these answers but these could all be part of the problem. It may be leaking more at #2 cylinder and causing it to foul more than the others. Also just because a mech pressurized the coolant system and didnt see any change in pressure (hopefully he wasn't just looking for visible leaks) the issue may not happen until the engine is hot, as metals behave differently when heated, especially aluminum which the LOWER intake is made. Have a mechanic or mechanically inclined friend (gearhead) remove the #2 plug wire, then kick the engine a few times without starting it, enough to let any fluid get into the chamber, this would include gas btw. Then remove the plug and look for any wet residue on the plug, gas will evap. quickly, antifreeze/oil won't. again try to smell the residue and if necessary, lightly touch some to your tongue, antifreeze has a sugary sweet taste that is easily detectable. Remember any time you are working with chemicals such as waste oil and especially anti freeze, minimize spills and clean them up quickly and completely and place the spent fluid in a sealable container and take them to a collection center for disposal. Waste oil is a carcinagin (cancer causing) agent and antifreeze (glycol) new or old will kill any animal (child, dog, cat,etc) that ingests it. Many auto parts stores and some other retailers that sell oil and antifreeze will take your wastes if you bought the replacement fluid from them, check before you buy.

check the sparkplug wires on the firewall side for arching-body seam there that will cut them

if you have the chip in the key, then this will surely help you: http://newrockies.com/vatsbypass . It was the only thing that saved my car.
SOURCE: 2001 Pontiac Montana - what is a misfire #5?
Without your actual trouble code, I am assuming that you are have a misfire on cylinder # 5. The computer cannot really tell what is causing the misfire only that cyl 5 is not putting out full power. If it misfires when cold then smooths out as it warms up, I would say it is probably an injector that is sticky, as it warms up it starts working properly.
Testimonial: "Thank you for your suggestion. I will have that checked out. I will also ask my mechanic what the actual trouble code says."
