hi all,im new to this today so..ive just bought an mr2 and a mechanic myself but never worked on one till now.anyway i have a 1993 toyota mr2 non turbo rev 2 engine.i have just replaced the engine to a rev 3 also changed the wiring harness for the engine and the ECU but its not running right.the car is revving to 4000 rpm and then cutting out.if i change the fuse box at the back and the loom going to the dash would it work? :confused:
