Hi all. Right the other day i cleaned my car as usual. Then everything seemed to go wrong. The exhaust went on the flexi part of the pipe so changed that, and now when i drive along it will not rev above 4000rpm and also sounds like its got an induction kit on it. Ive checked all the pipes on airbox and also changed the air filter. Also whilst driving if im light on the throttle it jerks like a bi**h. Today i cleaned out the throttle body but no change. I noticed that the wire for the plug connected to the tb were a bit dodgy with insulation tape around a couple of them, so i took them off and the wires were bodge by previous owner so i tried to re-do them but im not a mechanic so i done my best.
Please if anyone has had this problem before or knows of any information, it will much appreciated.
Its a 2002 1.6 Sxi. I believe the Engine Code is Z16XE
