Default CHECK ENG LIGHT P0100 Any ideas ????

Im haveng a huge issue ... check engine light on and wont come off. P0100 my car has run 12.8 trap speeds 108 -110.3 best so far but I went to the track last night and it was a nightmare .... It was nice and cold but the car ran like crap.

14.0 @ 103.5 BEST RUN.... Ive lost over a full second and major trap speed.


This is what i do know. Air temp sensor that connects to the elbow broke off but i manage to take the copper wires and twist them together. I just checked the MAF and everything looks fire but im not a mechanic. And I just notice Fuse in the engine was blown 20 amp.

what is going on any ideas

That is usually a MAF sensor Frequency code, make sure you have 5 volts on the pink wire (from the MAF sensor)
