But afer scanning dtc's it shows no codes. My car is idling all over the place also all of a sudden. It usually idles at 1100 now it goes from 900 to 2100 what is going on? Oh yeah I have 111 race gas in it now so i can spray it very safely.

I forgot I had a nitrous back fire last night and have decided it may be the tps. Does anyone know what vendor sells these?
