My car will not accelerate?


Asked by Mar 21, 2017 at 11:46 AM about the 2005 Chrysler 300

Question type: Maintenance & Repair

I have a 2005 Chrysler 300 and it will not go barely above 5mph when I press
the gas. It does rev up. It is not the throttle body. I have already taken it to 4
shops and they all thought it was the throttle body, but that did not seem to fix
the problem. When this happens there is a red lightning bolt that flashes on
the dash. Someone PLEASE help me!

I just towed my 2006 to a shop for the exact same issue, when you start your car does it idle rough and feel like everything is shaking? If you put it in gear from Park to drive, does it get worse? When you are driving it, the lightning bolt light flashes? If all this matches, I will let you know what the shop tells me, I have already been to 2 shops that told me nothing was wrong.

That sounds like a slipping transmission or it could possibly be a transmission control problem. I would take it to a good transmission shop for diagnosis.


I thought it might be my trans. As well but the shop swapped a map sensor, cleaned out ETC then after they told me all was well, cylinder 1 was misfiring. I took it to an auto/electric mechanic so hopefully this will be the last visit to a shop for a while.


@Grindin247 yes, all of those are happening! Please keep me updated!

That is a air leak in your manifold. Check all hoses connect to it.

I had the same problem that lightning bolt is a loose hose. The recently behind the manifold is classic for coming out the manifold because it's metal and the gasket goes bad on it. Find the air leak and that should fix it.
