My car will not accelerate?


Asked by Feather 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.

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.

I have the same proble did u fix the proble

I have the same problem my mechanic got the code for the throttle body car ran fine for about 45 mims now doing it again i was told ita the accelerate pedel sensor please tell me its not my trans


vacuum leak from the EGR pipe or where it goes into the intake manifold.


This is hilarious. Im hearing sensors this sensors that. I just chnged my 300 water pump those idiots at chrysler put it behind the timing belt. I have no tranny dipstick, bot i have a hole for one, my a/c recharge valve is positioned under the aluminum refrigerant line, so i cant use a store bought can to recharge. Chryslers are garbage. Aluminum engines and plastic everywhere else.

Your lightning bolt is due to a EGR or ERG valve stuck open/close. Rought $50 to $60 dollar part. Between firewall an motor closer to the passenger side. What was causing every problem listed on this page.

Ok so you are saying that the egr valve has to be replaced to take the lightning bolt off and this will fix the acceleration problem and the poor idleness?

My car is doing the same thing replaced egr vavle cleaned the egr tube and replaced seal on tube going into inatke. I replaced my throttle body my pedal sensor and pcm!!!! What could be the issue?????? I go for miles then the red lightning bolt comes on and I have no acceleration and have to pull over. Then I start it again it's fine for a while but always does it again? Could it be a loose wire somewhere ?

My 300 just stared moves when its in drive or reverse..but when i press on the gas all it does is rev up the engine..


Check for airflow obstruction between the airfilter and throttle body. I had the same symptoms. Turned out to be some paper towels stuck in the airway, before the throttlebody. I put them their when I replaced the timing belt. Duhh


I have read that it is an issue with the engine wiring harness having a wire break from moving so much, a tech said he learned that and that is what has fixed all the ones with them issues that have came into his shop.
