Hi all I'm new here, my expy is 1998 xlt with 4.6 and 313,*** miles. Last Monday I took it out for a drive since I had to move it for snow plow, it was running great and everything. Then have not use it for 3 days due to extremely COLD temps and did not have to go anywhere. Of course battery went dead which didn't surprise me. Jump start last night and it runs rough, so let it run for good 15, 20 mins to recharge up battery. Tried it today it started no problem but runs really rough, so took out for a drive after let it warm up for half hour or so. I slam the gas pedal all the way and it moves like a snail rpm would go high and seems like it cant go over 30. *my guess since my speed cluster not working. Transmission fluid is good, coolant is good, etc... So I was wondering what could be the problem? My brother plan to look at it for me sometimes this weekend. Thanks for your help!
