Service engine soon light

Nope no leak and I am now getting a code for my bank 1 sensor 1 no activity?

I have this wonderful car.(Sometimes) well, the check engine soon light went on? Code was for cylinder 1. Changed spark plugs. Now car is making funny noise.. And yes the car overheats. Too. Finding out that's normal. But I drove it on a trip it ran fine didn't even overheat. Come back home to Redding, ca. Where its hot and it starts to act up. Go figure. Well what do you think is going on with my car. I have changed water pump, thermostat, coolant resivor and cap. Which helped for a while. NOW what? :(

Yes I have checked the fuel pressure it is fine ive never tryed a smoke test is this something I can do myself or must I take it to a shop I dont have my scaner anymore so ill have to take it back to autozone to get my code again ill post when I do

Yes it does overheat. Have to add water or coolant requalarly. Not to worried about that part. The funny noise. Sound like it is coming from the alternator. Its a taping sound but its not my valves. We just changed the spark plugs. But now the service engine light is blinking. So I am not driving it. Due to reading owners manual say that could cause more problems. But after changing the plugs car now runs slugish.

1999 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic

I just bought a 1999 Grand am Gt, and it has a few items on my laundry list of the car. Any help is much apreciated. 1. My blinker when I turn the right turn light on it blinks really fast ( blown bulb.) But I check and all the bulbs are going there dim. But going and its not in the same pattern as the left. Also after I turn it off I will still hear the clicking although its not in a set order it can be 3 fast clicks, a pause 1 click, a pause 2 clicks. Etc. 2. My abs and trac control lights are on. 3. My right break when ever I use it, it sounds like someone walking across a old wood floor. 4. Services vehicle soon, and service engine soon lights are booth on, I took it to autozone they said my gas cap. But why would that cause both of them to be on? And I don't know if im crazy or not but it seems like the service vehicle soon light only comes on in the day time and at night it does not. Please email me - Rockthistrend@hotmail. Com thank you so much, Eric.

It is a 99 grand am. With a 3400sfi engine. Yes it does overheat sometimes but I always make sure it has coolant in it. Like I said it didnt overheat once on the road trip. Before the service engine light when on it was running but it wasnt as slugish as it is now. It was not making a taping noise at all. It had a squeal that I believe was coming from the power stering pump. The code for the service engine light said cyclinder 1 misfiring.

The plugs looked fine. Wernt oil ie or no ash. Just looked like normal plugs needing to be changed.

hesitant to accelerate, turnin ac on will cause to stall
service engine soon light on, is it cylinder misfires related to coil wires? How expensive of a repair is this?

While driving the car yesterday, it lost about half it's
power, check engine light came on, also low trac lght. Engine idles rough, with raw fuel smell coming from the exhaust. My question, under the engine cover is a odd looking coil pack? Maybe? Can this be tested, also can the ignition modual be tested?
