Got a series 1 1.1 xn, idles roughly and I keep getting hesitation under throttle. Picked up a series 2 1.1 today, will the injecter body (bascily like a carb) fit my earlier car? Was thinking if I change that, that might help, then if it does try other things?

It well could be a vaccum leak somewhere, or has it been serviced quite regularly? or it could be ignition problem i.e HT Lead, Spark Plug etc.
