i need help fixing my car there is something wrong with it. while driving around my car starts to die on me. it only dies on me when im on 2nd gear or higher it will go from 3000 rpm to like 0 and jumpes up and down. if i hit the clutch in and get to idle agian then it will be fine. but if i don't do it in time then it will stall. when the rpm jumpes up and down the engine jerks big time. i just bought the car a month ago and recently this problem occur. i already replace the negative wire from the battary and replace the battary like on monday.it doesn't happen very often. just once in a while and that sucks. my car is a 94 honda civic si with a d16z6. i got ripped off for the ecu too after i bought the car i redlined it and it only went to 6500 so i checked the ecu and it was a p06 dx ecu. can that be the problem. please give me feed back asap!

 

bump for some help!
