Asked by OwenW Nov 19, 2018 at 10:48 AM about the 2006 Pontiac Grand Prix Base

Question type: Maintenance & Repair

There are a couple things going on with my 06 grand prix...
It'll die going down the highway or sitting in a drive thru
without any spit or sputter. Sometimes you have to press the
throttle to get it to start. The transmission fluctuates in
overdrive mainly between 65-70 in a very slight pull, but you
can drop it into 3rd and it does fine. And now it's taking
longer between shifts. What should be my priority and how
do I go about fixing it?

FIXED- It was dying randomly. After replacing coil packs and the ignition control module, it was still dying. Replaced the Crankshaft Position Sensor, and that did the trick. I actually think it was a bad connection to it, so make sure it's clean.
