[QUOTE="CudaCobraSVT, post: 16598509, member: 136781"] This is only my second post ever, but I hope someone can help because I am at my wits end. I have a 99 Cobra with 240k and a few bolt on mods (MAC CAI, Borla Catback, Steeda Underdrive Pullies, John Lund Tune). Used to run really smooth. Now after I had my clutch replaced (thought maybe the disconnected something) it runs rough and hesitates at light throttle, but runs great if I run her. Also seem to be worse at lower altitudes. I live at 7400 ft. and drive to work a 5400 ft. and it gets worse. I have tested for a Vacuum leak and replaced some of my hoses. Sprayed everything with Throttle body cleaner. I've also replaced bunch of things ... [LIST] [*]Accufab Throttle Body [*]PCV [*]Spark Plugs [*]IAC [*]MAF [*]TPS [*]Gas Cap [*]Vac Hose at Oil Separator and to Vapor Canister Purge Valve [*]Vapor Cannister Purge Valve [*]Oil Dip Stick [*]EGR Pressure Feedback (DPFE) Hose / Pipe [*]EGR Pressure Feedback (DPFE) Sensor [*]EGR Valve [*]EGR Valve Control Solenoid / Motor [*]O2 sensors [/LIST] Appreciate any advice. Thanks, Joe [/QUOTE]
