rough idle on 93'

ok so heres the deal.i bought my probe bout a year ago and almost immediately put a cold air intake on it.then it would bog down and have no power when i got it out on the road.i then found some sensor adapters and had no problems after that.i was driving it the other day and it was fine.then i shut it off and when i started it back up it was idling rough and when i got out and started driving it bogged down.acceleration is just as slow in 3rd gear as it is in 5th.it just doesnt want to go.i gave it a tune-up and put on a new air temp sensor.it ran perfect for bout 10 minutes and then it started all over again.could it be the coil? thats still origional as far as i know.ideas? help please my other cars are gas hogs!!!:banghead:

hey check the seal on your intake. If its loose and there is any air leaking that will bog it down bad it happened to mine, make sure the clamps are tight
