AT about 100mph in 4th gear My srt6 just flattens out and refuses to accelerate any more also the pa esp light light came on. Possible cause? thanks

 

Some similar postings describe an issue with CPS

Also, a posting here with BAS ESP light and acceleration issue indicated a wiring harness issue with throttle body.

Thanks you have been very helpful.

I haven't had this happen in awhile, but while testing at the track, I have had the throttle pedal come unhinged and ride up on the mounting. This will result in less that full throttle. I know this isn't your problem but may be a problem in the future if you do many full throttle launches. Might try a throttle reset. See if it helps.

 

thanks I will give the throttle reset a try.

 

I remember a post where something like this happened because of tire sizes, what size tires do you have and are they all the same diameters side to side?
