2.4l spark plugs
 

Has anyone had any problems with different brands of spark plugs?
My wife's van had an issue with Bosch plugs, it just ran like dog dooo dooo.
Plain old vanilla Autolight ran fine. According to a Olds tech there is a difference in the internal resistance that messes with the ECM. I was wondering if the quad 4 had the same issues?

I replaced the Bosch with plain old vanilla Delcos and It's like night and day. no more stalling, no hesitation on highway acceleration.

Next time try some platinum plugs. They're a bit higher in the heat range and with the 2.4L it will help give you better MPG and better performance.
