Hello everyone, Lately my 240 is idling kind of funny when I first start it up surges to 1500 and back down to stall unless I can keep it running with the accelerator after about a minute or two the idle evens out. the car is also real sluggish off the start and climbing hills once we get up to speed I can go 65-70 no problem car rides great. In the last couple of weeks I've replaced the knock sensor,in tank and main fuel pumps and AMM.(thanks to all you brickboarders for your help and encouragement} Also What are the symptoms of a bad catalytic converter mine looks like it might be bad it doesn't fit very well on the next pipe down stream and visibly leaks at that joint. could this be the cause of some of my trouble? Thanks DK
