2006 GMC Envoy Denali, 5.3l v8 4l60e
- Exhaust setup
- Cold air intake w heat shield
- New starter
- New battery
- new alternator
- new oil sensor
that’s about it for modifications and or new parts recently put on.
For the last 3 months of having this car every-time I put a full tank of gas in, it it will have a small rough start and sound choppy at first. The other day I went to start it and it took a good 10 seconds for it to start up. After it started it was rocking me side to side and sounded as if someone put a sport cam inside my car while I was sleeping. After 10 seconds of it running it went away, during that time there was a lot of smoke coming out of the exhaust, it went away fairly quickly. It started to idle smooth with occasional spikes.
After I let it warm up for a few min I take it to the gas station, coming to a complete stop my car is revving to 2k rpm in drive at a full stop. It was forcing me to go forwards and almost hit someone. When I go to park or neutral it will do the same thing.
I turned the car off fearing it would try and rev higher and blow up, ever since I turned the car off and filled it with gas that day. It will not start AT ALL NOW. I had to have my dad pull me home in his truck with a strap. Already used all my AAA towes with this truck this year.
About a week ago I got a crank shaft position sensor code but it went away, I also have a evap purge code. Only codes that will affect anything. Now no codes will appear. My battery keeps dying while trying to start the car. Battery was fully charged and wouldn’t start the car either. I tried 20 times and died again, I’m about to fully charge my battery once again and try again.
What you guys think it could be??? My ignition lock cylinder is also not opening with charge which is new after this happened. Maybe it is my battery?!
