Car remaining with CK plates.. converting to awd. Engine, colour change and inspection will need to be done. I heard ppl getting trouble with inspection when they tamper with the floor and sometimes engine change if the find "its too big an engine for the CK chassis. Doesnt make sense to me.
Had the same issue with my scooby some time ago with no check engine light. Turned the MAF sensor was bad. You can try cleaning it first before looking at replacing it.
It should but I think it may not be just a bolt up as there are little differences in generation. Have a sale pending at the moment so I'll keep you posted
