In the last two weeks I added three new mods to my car all pretty Stright forward things but my car is acting up any input would be great. First I did a tune from eurocharge everything seemed great the car reved a lot quicker and didn't feel as bogged down when I got on it and the clutch felt a lot better, then about a week later I added a 74mm throttle body which seemed to bolt on and plug in with no problems and a NW intake at the same time. On start up the car reved but wouldn't come back down so I shut it off and restarted it and it seemed fine but my tune didn't seem to be there anymore, it seemed bogged down and the clutch felt the same again. The next day I drove it to work and at an idle it would rev about 500rpm so I pulled the batt to reset everything and then my tune came back but it was still revving weird so I pulled the maf sensor out and made sure it was in tight and clipped together good then it seemed to be good again but it revved up for on reason later that day and wouldn't drop back down besides that one time it was good now this morning my tune seems to be gone again? Any ideas I got my intake and throttle body used so I didn't have an instructions but it all seemed pretty Stright forward idk tho?
