95 Escort ruff acceleration/hard starting
Ok I have a 1995 Escort wagon 1.9L SEFI. The car has 75k original miles. The car runs great most of the time. I have been having an odd problem that started about 2 years ago. First let me say that i bough the car 2 years ago from my grandmother, she put about 3500 miles per year on it, so it would sit for a month or longer some times. Ok now on tot he problem, since the day i got it (october 2008) it has trouble starting and runs ruff, but only under certain outside termperatures. It started off 2 years ago that around 45 to 55 degress outside the car would take anywere from 2 to 8 seconds cranking to turn over, once started it would sometimes run fine, other times ruff like it was missing or only running on 3 cylendars. Once going at a steady speed it is fine, but when accelerating it is very jerky and ruff. Once the weather gets colder around 40 or below everyday the cars fine, startes right up and runs fine. Same goes for the spring when it warms up to around 45 to 55. Now two years later I am having the same problem but seems this fall it is a wider temperature range more like 35 to 60 or around there. I am worried that this winter the problem will not go away like it has the last two years. Also the problem seems to get a little better once the car warms up, but does not co completly away. Also the idle is fine once, not ruff or high or low. Just accelaration is ruff and seems like engine is missing, and hard time startting. When getting onto the high way or having to pass a car and accelerating it jerks hard and full power kicks in for a sec then away then kicks back in then goes away untill i level off the gas pedal. It just puzzles me that this problem only comes for a couple months of the year. PS I live in cleveland ohio so winter is usualy 25 to 35 every day and summer is around 75 to 85 so this si only as problem twice a year for a few weeks streight.
Also I have not done much to the car since I bough it. Regular oil changes and a tune up about 5000k miles ago with plugs wires fuel and air fulter and that did not solve anything.
Any help would be great!
