Hello please help I have a problem with my 2005 Crossfire sputtering on take off and on low rpm's. On the freeway it feels like when I step on it if cuts out a bit too. It's like when I accelerate too quickly it always happens. I don't know where to start I used a scanner and it says random cylinder misfire on 3,4&6... When I stand behind the car it smells like excess gas coming out of the exhaust.. It's a manual coupe v6.
Please help thanks guys

 

Sounds like it's running rich or choking on clogged air filters. Also, you told us all about your car but for one thing: how many miles?

Between 75000 and 100,000 miles, the car needs plugs and plug wires. I had misfire and O2 sensor codes along with sluggish performance - put in 12 plugs and 12 plug wires and ALL codes went away; and the car ran like it should. It went down hill so slowly, I'd not realized how sluggish it had become.

(THis was the middle car pictured below, just FYI)

 

I"m wondering what a filthy or just BAD MAF would do as well.

 

Could also be a vacuum leak ......

 

My '05 Coupe started to stumble a bit when stopped for a light, even threw a CEL which came up as related to Throttle Position Sensor. I did a bit of research online and came upon this article: P0121 - OBD-II Trouble Code

So I took that bit of advice to heart, picked up this kit ( ) and spent a few minutes cleaning the MAF and throttle body. No more stumbling at stoplights or hesitation when getting on the throttle.
