hello i have a 2001 300m and i have a few problems with it ok first for the last couple of months when ever i am driving when ever i press on the gas there is this loud rattling noise that sounds like its coming from under the hood i have been to a garage with it and they seem to think it's my converter you can put the car in reverse and hold on the brake and give it some gas and you can here the noise clear it sound's like it comeing from the passanger side right next to the motor has this happened to anyone else or does anyone know what this might be? p.s when i here the noise it fells like my car is loseing power while the rattling is going on..
 
and my next problem just started my car ran out of gas and my engine light came on i went to auto zone and they ran a test and it said there was a misfire on four of my sparkplugs so i changed all 6 spark plugs and the little ruber boots that sit on top of my spark plugs my engine light has gone off but now when i go to accelerate the car fells like it wants to kind of be slugish and it jerks back for a second like its not getting gas to the fuel tank do you think it needs to be replaced or has anyone had this problem

I have a 2003 300m with 72000 miles. When I start up the car I hear a herendous rattling noise and there after a hard knocking noise/ticking noise. It gets louder as I press on the gas pedal. One mechanic told me it was my camshaft or my extension rod and that I needed to replace my engine. Is this a common problem? The knocking noise appears to be coming from top of the engine not below. Can any one help me with this one?

we have a 99 300m and think we are hearing the same noise...2 mechanices outside of the chrysler dealership said it sounded likes rods...we have been hearing this sound for 12 months! today we went to get the car from the transmission shop and they said it sounds like it is in the front of the engine and heard it before on a 300 and it ended up being the timing belt/brackets...I don't know alot about that area but when he lets me know I will respond back again...I am afraid it is costly...the whole front end has to come off!

Thanks for the info. I took it again to another mechanic and he also stated that it might be rods or the crank shaft. The timing belt/brackets suggestion is a new one for me. Yes, it is very costly. I recently took out an extended warranty on this vehicle so my deductible is only $100.00... I will keep you informed.

Similar problem in a Caddy my wife drove. Turned out to be a belt pulley with bad bearings. I can't recall if it was the belt tensioner wheel or another pulley. Luckily, it was easily accessible and not very costly to replace.
 
Good luck.

My 2002, 300M engine starts jerking between 2 and 3 RPMs. What could be the problem?

My car is slugish or it jerks whatever you want to call it. When you take off and the needle gets up between the 2 & 3 RPMs it starts jerking back and forth. Or do you call it slugish. I have taken it to a Dealership and had a diagnostic test. They arent sure what it is. It could be 3 different things. Timing Belt, Fuel Pump, or possibly drive plate. So much for a diagnostic test. What a waste. I would really like to know. I love this car. It only has 73,000 miles on it. Now the check engine light is on of course until we fix the problem. If anyone out there knows what it is or they have had some experience with the same thing please let me know. Thanks

Jan 09, 2008 (12:23 am)

My car will all of a sudden stall. it usually happens when i am just about stopped. i can put in neutral and start it back up but it is getting annoying. also when i am driving at highway speeds it will some times feel like it chugs. i have done a fuel system cleaner and that didnt see to help at all. is there any explanation for these things?
