Car not running right. Help

[joeyv19]

So I've been having some problems with the gp. Rough idle, studdering, loss in power, running rich, sounds terrible like it's not running on all 6. SES flashing, Threw a P0300. Basically running like crap. When it first happened I cleared the code unplugged the battery for 15 min and it started up fine and went away. Then 15 min later it started again. So I changed the plugs and wires. Still doing it. Scan Guage told me it's cylinders 1 and 4 misfiring. So I changed the coil pack for 1 and 4. It went away then came back a day later. I swapped out coil pack 1 and 4 with 2 and 5 to see if the new coil pack was faulty and it was still misfiring in cylinders 1 and 4. I unplugged the MAF and it reads no misfires but still runs like crap so I also replaced the MAF but that didn't change anything. I heard the injectors don't go bad very often in these cars especially two at a time so that leaves me to believe it's the ICM. It's a 97 se 3.8 80,000 miles. Any ideas would be greatly appreciated. Thanks.

use a long screwdriver and place it on the #1 injector and put you ear up to the screwdriver if you hear a clicking noise that increases with the engine speed then that injector is working. You can do it on a known working injector to know what sound your looking for. I would start with that and see what you find out. Then do the number four cylinder. If thers no clicking noise its a bad injector.

Thanks for the tip. I just tried it and all 6 are clicking perfectly and increase with engine speed. So I guess it's not the injectors

When you pulled the plugs were any broken?

[joeyv19]

Nope the plugs were all in tact

If it were me my next step would be to make sure they are spraying right. I would pull the rails out and turn the key over and watch all six with the engine cranking make sure its a fine mist pay extra attention to the one and four cylinder. Be careful and put pig mat down and dont smoke obviously but i would try that and see what the results are

I fixed it it was the ICM. Swapped out for a new one it's running better than ever. Thanks!
