When I got the car it was already swapped and it had a problem already with power loss after it warmed up, now every once in a while when I start it up the check engine light comes on and it cuts at like 4 grand, I'm not sure if its spark or fuel cut, its extreamly hard to drive since I can't rev past 4 grand in every gear and again if its warm it has a hudge power loss so if I'm going up a hill I have to go slow and stay below 4k rpms so I don't have to gear up. Any help at all would be great.
 
is it a dx? can you help me i need the wires and the location on the plug on the drivers side shock tower.. thanks my cars doing the same... unplug the map it runs and idels fine for 300 feet then cuts out super bad also..did you eliminate the resister box?
