My 2004 SRT-4 is 2000 miles old. For the past 1000 miles, I have been idleing at 23psi in vac., and when I get on the pedal hard, I might be able to break 0-5psi. I know something is wrong. I always use 93 octane, and the SRT-4 is stock. First question for SRT-4 owners, what is a normal idleing psi? Second, what could cause this? I am going to take it into the dealer, but I want to know what other SRT-4's are running so they can't tell me everything is normal.
