aircon removal and misfire
 

Hi I removed the aircon and now the fans come on when i rev the engine!
I'm thinking i've done something wrong:jerkit: I had an st205 celica gtfour and when you removed the aircon on them you have to leave a sensor connected? same here? or ive got a short help....

also develpoed a misfire, changed plugs still there.
when I pull the boots off the coil get good spark on two cylinders weak spark on two?(thinking coil pack)

Any help would be greatly appreciated.
