Ok my car has been running great. The only modification that i have made to my car is that i installed infinity basslink over the weekend. Normal idle around 850 RPM's. Today i drove the car normally. havent hit Vtec in a few days. Today i immediately noticed that my idle was bouncing between 1200 and 2000. First thing i checked were all vaccum hoses all were tight and were in the right places. Fuel pressure is at 47 PSI WOT. I thought it might have been the weather cause this is the first time that the car has seen these tempatures 24-38 degree's . Then i took it to the normal vtec point at 5600. It didnt engage. so that threw me offgaurd. But vtec now engages at 6100. What the hell is wrong with the car? cant figure it out i unplugged the TPS sensor and IACV and the car just died. not sure if it should have done that or not. ive never had either of these sensors go out before. Is it the ECU? Thanks all input would be appreciated.

 

common cant someone help me??? also the engine doesnt wanna go past 82. i use to be able to take it to 86 or 9 like it was nothing now its struggling.
