hi im jeff hunter and new to this and all and have alot of friends that do this and get good advice so i said what the heck.

i have a 98 dodge ram 1500 2 wd 5.2 liter . i love this truck and never had anything wrong with it since i got it. til now 2 weeks before we move. well my problem started a week ago it started slipping in second gear when you had to give it gas it would work perfect if you drove it normal. well i decided the other day to change the tranny fluid and filter. well did that filled it up and went for a drive well i got to get on a high traffic road and couldn't get the truck to get up to 30 mph. its like it just fell on its face. well i checked my plugs and wires and they are good changed them like 6 months ago. checked for vacuum leaks and i couldn't find any. so take it and get the codes in it and they tell me that its multiple misfires and o2 sensor and could be a vacuum line or something. please help i lost and please let me know if there is something i missed or is something that can be done? thank you for reading my thread.
