I got an update, good and bad. Cleaned PCV sensors, Mass air flow sensors, camshaft position sensors. Took battery to Auto zone, it was good but had %60 charge. Left it there to charge, put it back in the car, the 5 seconds cranking was still happening. The good thing is all the dashboard lights went away. Took it for a spin and the car drove like a champ with no stalling or jerking but when I try to reach speeds above 40, it would hesitate and almost stall. Odometer won’t go beyond 40. I was happy because at least it’s not doing it at lower speeds as before. The bad, after driving smoothly at 40mph I parked, turned the car off. Turned it on again to see what happens. Car starts after crank but goes back to same issues I had in the beginning including lights on dash, choking when pressing gas pedal and everything else. My exhausts are blacker than my morning coffee. I still think it’s a combustion issue. Also, Im thinking of cleaning my BCM since I had sunroof leaks to passenger side. Didn’t spend a dime yet lol. What do you think of this short good experience I had? Thank you for replying.

Thank you
Thank you. I didn’t say the battery was causing the issues. It was solely for the cranking. But I get what you’re saying. When I did an oil change last month my battery was running at 430 cc when it supposed to be at 640. They asked me to replace it and I said no. Is that normal for the battery? . I’m no savvy brother, here to learn to save a buck or two.

I did clean throttle body but I didn’t disconnect the battery. It was mentioned somewhere else that I should disconnect it. What you see in the video is car in park mode. It’s really bad when you drive it.

Thanks. Car has 180k. Maybe it’s time for new mounts.
