Troubles while Idling and Driving slowly

[99ChevyMalibu]

Hey!
Yes, I did figure it out...sorry to not repost the solution....
Basically, it was the spark plugs/wires were misfiring. Had those replaced and she is running great!

99 malibu, I have the same exact problem as your car......basically started right after I replaced my spark plugs and wires and it has been running bad for more than a year. Do u have any idea what brand spark plugs and wires you got installed on your car??

What brand of plugs & wires did you use? I have found oem by far the best for these picky 3.1L engines, oops forgot to ask do you have the 3.1L engine?

Actually.....I used Bosch +2 Pre-gapped plugs and I used a no-name 35 dollar set of wires. Yea I do have the 3100.............should I just change the wires or just redo everything??

I've had problems with bosch plugs, not on my malibu but in my mustang gt, I don't like em at all. Switch back to the stock delco plugs first before the wires and see if that makes a difference.

From what I've learned, the Bosch plugs are rated one heat range colder than recommended for the 3100. This would translate to ~20k miles of use compared to ~60k-80k of use from a delco plug.

I usually pick up wires at the same time I change plugs just incase I break a wire pulling it off an old plug. No matter how careful I am it always happens, if successful then you return the wires or stash 'em.

Use anti-seize on the plug thread and dielectric grease on electrical connections.

I agree on having wires handy, those ends pull off easily. I would go easy on the anti-seize and use a Torque wrench for sure. Make sure the motor is stone cold when you change those plugs. Do not put the dielectric grease directly on the plug terminals, just a little bit on the inside rubber part of the spark plug boot.
