I have a 1996 Grand Cherokee Laredo I6 4.0L that when you start it it sounds fine then after about 3 minutes the engine sounds like its going to die and the RPM's drop to almost stalling. it only lasts a minute or so. now it seems to have a rough idle. I have replaced the fuel filter and plugs but this started before this. it has 135k on it. Everything else has been kept up but i think after a few rough towing trips a few months back it might have screwed something up. Please help....
