i hope that this will be the last post for this 97 geo metro. i need to move on to better things. the last time i posted a message, i was having problems with this metro of my wife's where it was wanting to not start after it has been running. a couple of you out there suggested that the egr was at fault. since that post, i tested and cleaned out the egr valve and replaced a special vac./ elec. post that is located under the egr modulator. i got out to run it and the dumb thing again acted up. it is only doing this when the weather is warm or hot. upon returning from the local grocery store, it would run fine for a couple of minutes and then start sputtering. the engine would all of a sudden drop to its idle speed and if i try to give it gas, the engine would act all retarded like it was getting too much gas. as soon as the car would coast to a stop, the car would die. i would have to get out and take off the air filter cover and it would restart (most of the time). it is getting gas and is falling in the specs. for fuel pressure. what am i missing here? it is something so close and in all likely hood very simple but i am missing it. help?
