I have a boosted civic with a rebuilt b18c1 tuned on ectune. I had a problem with the 3 bar map sensor harness so I took it off and fixed and put it all back on and now when I start the car it starts normaly and has small idle surges. When I open the throttle much at all it just acts like nothing works and dies. I noticed when doing this in the car when I open the throttle enough for the boost gauge to go to 0 thats when it starts dying. Any help would be great. I just want to get it running.

thanks

 

Ok so I found out that its the tps. I unplugged it and it acted the same. Now the prob. How do I know if its the TPS or the wiring?
