2001 Ford Escape, very rough idle and stalling only when it is cold.
Hello I have a 2001 Ford Escape XLT V6 and for the second Fall / winter season I am experiencing the same problem. When it starts getting cold out I can start my vehicle just fine and within 3 seconds it will start to idle extremely rough. It spits, and sputters, jerks and shakes and will eventually stall out unless I give it some gas. I am able to drive it like this, but when I come to a stop it does the same thing and will stall unless I put it in neutral and give it gas. This happens for most of my 10-15 minute drive to work and then once I get there and the engine seems warm, it will idle and run fine with no issues. Then of course when I go to leave 9-10 hours later and its cold again the same thing happens all over again. I have been to 3 different shops including a Ford dealership and the following work has already been done but the issue is still there. Replaced the fuel pump, fuel filter, air filter, all plugs and wires, 2 of the coil packs the read faulty when checked, IAC valce and cleaned the MAF sensor and had it tested. Unrelated I have also changed the alternator and water pump. The shops are out of ideas and so am I. Any ideas what this could be? This only happens when it is cold, I do not have this issue in warm weather. Also the engine light is on and it is throwing to codes P0171 & P0174 bank 1 and 2 are lean. I am not too mechanically inclined, however I don't have much money to have the work done and I do know how to do some things and I am good with instructions.
