i have a 93 4cyl 5sp car. my problem is in low rpm the engines seems to spit and sputter. when you rev it up it sputters and then will clear up above 3k rpm. also when its completely cold it has a hard time staying running and when i go to leave it will spit and sputter for awhile. it will also do it when im under a load such as pulling a hill. now the thing is today when i left work it started up idled a little funny then i took off up the road. with barely any hesitation it was about 93 degrees outside. so i feel like it is temperature related. maybe not. i just put a new maf on it and it didnt fix it. i really am lost on where to start so some help with this will be much appreciated. thanks everyone
