Tim, the fuel presure in idle is 40 psi, 45 when mash gas petal. Don't know about taking off the exhaust system. I have had this thing at Merchants tire aka Tire King. They cannot find the problem. Drives awful cannot pull out in traffic or accelartate from stop light. in iddle and while cold runs like a champ. NO codes in computer. No sounds from engine, just has no power.
