ok here it is driving down the road today an car suddenly loose's power like i took my foot of the gas ..then i taped the gas again an it started bucking like crazy so pulled over an was idling like crap...took off an was fine for about a mile then did it again.. so check an cleaned plugs an wires everything good there..checked timing good there drove again still doing it..ok so i go back home check TPS sensor an was a little off but fixed it....drove it still doing it.. while car is idling in the shop i pulled the ecu from under the carpet an the car suddenly jumped into a higher idle? then came back down touched wires again idled high came back down does this sound like a jumper harness problem>???

 

More than likely. Pull the ECU out and the jumper and check all the wires and connections over, see if you can't find a lose one and broken wire or somthing.

 

ok yea i cant figure out what else it could be when i got the car it had a ls swap. but it was a homemade jumper harness i mean it looks like its done correct but could just be a loose connection some were
