check oil to see if there is rad fluid in it. if there is you have a cracked head or head gasket. if no rad fluid in oil, check for a spark.pull out a spark plug attach spark plug wire hold close to engine block with gloves and turn over engine. it is best to have someone with mechanical know how to do this,i.e. friend or nieghbor

Check engine light is on and says air intake sensor where is that located on 1997 Pontiac Gran Am?

Locate the airfilter box. It is most likely on your right hand side when you open the hood. Once you locate the box which is pretty hard to miss you follow the large hosing that runs from the box to the engine. This box filters the air that your engine breaths to run. The sensor is located somewhere on the hose usually closer to the box. Check that it is not lose our falling out. If not your might want to remove the box and clean the sensor or see if it needs replacing. Box is easy to remove and replace.

Gran am 1999 se not gt it's 2.4 I changed the sparks plug and the connectors, took apart the cover so in auto zone they can read the coil to see if it was o.k. they said it was ok, my car still shakes...

Try and replace the coil cover, or coil tower as it is sometimes called, also replace the rubber boots at the same time I have these covers internally short on me before

1999 gran marq has new alternater,fuel pump and filter,spark plugs and boots but still skips while idleing and mostly while accelerating,,,getting worse also

I will try to add a few things to check. It sounds like bad plug wires or a coil going out. Sometimes if you water mist the coil and wires with a spray bottle you can see the sparks jump. It will be easier to see in a dark area with the motor running.

The Intake manifolds were changed from metal to plastic to prevent carbon buildup in the EGR passage. This would be under the Metal Airhorn and under the gasket where it attaches to the top of the Intake. There is a groove to clean that carbons up and throws bad codes and interferes with the engine running good. 8 bolts and a $10 gasket and 1Hour of your time to fix it.

You have not mentioned any codes or testing results. Your onboard computer can be checked for free at Autozone or Oreillys. Your "check engine" light should start setting defect codes if your misfires are getting worse. Also, if you can remember a wet plug when you removed your old plugs, that would be a good indicator of a bad wire for that cylinder.

Let me know if you have been fixed.

1985 gran fury. i've changed the distributor,the brain, the coil, the ign. relay, and the rotor and cap. the car fires when it wants to . more like it starts every other day i have no clue what to do

I'm going to assume you have a 318? Also going to assume that the wires and plugs are in good shape? When it's not starting, do you have spark? If not, do you see spark for any part of the time when you crank it? Have you made sure that the carb is OK and not flooding the engine?
What I just said is'nt a "fix...yet...I need to know this stuff first.
