Hello and help !! I have a 1993 Cherokee country that I bought new, it has 347,000 miles and up until now has never given me any major problems. It is 4.0 i6, automatic, 2 wheel drive. The problem started about 2 weeks ago, when I started it sometimes it would run rough, I could turn it off and wait a second then restart it and most of the time it would run fine. Well now it only runs rough and has a miss. It feels like its starving for gas. I have replaced the catalytic converter (it was already rattling), plugs, fuel and air filter, throttle position sensor, the crankshaft position sensor was replaced about a year ago. The last time i drove it I had to really press on the gas pedal to get home it. The only code its throwing up is 55.

thanks, Mike
