I've got a very stubborn jeep that just won't stay running. I've been fighting it for a year now. And since has improved. But I've been just uses sing and I need a way to solidly diagnose what's going on with it. It has a 2.5l 4cyl Tbi. The issues I'm having is most defiantly effected by the weather and climate and time of day. But the issue seems to mostly fluctuate with time of day. 1. So in the morning at like 5:25am I start it to warm up before I leave for work and it'll start and run just fine till it got to be about 100 degrees then it'll idle down to like 300 rpm and stall ( unless i floor it and hold the gas then it would run fine and do it again. 2. some days it floods so I have to give it gas to get it to start and it'll be fine for the rest of the day. 3. some days (seemingly more humid) it'll start fine or it'll do the first problem mentioned but as I give it gas ( like to go up a hill or some thing) I lose power and then it kicks in again till l let off the gas then give it gas it'll repeat. 4. It kind of goes along with issue 3 it hesitates or "fish biting" effect with acceleration I've replaced fuel pressure regulator, ignition coil and module, spark plugs and wires, distributer cap and roter, timing chain. Last year i did have issues with the injector but since has been fixed. And in the fall the map sensor went bad and almost left me stranded. I did some digging in the Internet and tested the egr and it wont hold vacuum so that's going to be replaced here soon but I don't think that's the issue but it could be playing a part in it
