My 96 import is hesertating under hard aceleration. Its as though the fuel is not getting through. The car is fine until it gets really hot. Once hot it seems to not be as powerful even when not hard excelerating. Any advice

Hesitaion could be a number of things.

Crank sensor.....Determines the ignition timing. iirc either works or it doesn't.
Lambda sensor......at fault. Its function is to Adjust fuel map. So could be that.
Mass air flow control vlv........dirty
Plugs.......incorrect gapping, electrode break down.
Coilpack/s faulty.

Any ecu chk light on at all?

I agree, could be numerous things, you need to try a process of elimination.

Coil packs are my first thought, around £65 each, pricey to change all 4, try removing them 1 by 1 and inspecting under the rubber covers for cracks in the plastic, replace suspect ones or try and borrow a good set from someone else to try.

Hi there, exactly the same thing was happening to me when I first got my car and I got all worried about the expense of all the above mentioned things and not even knowing if replacing them would fix the problem. My g/friends brother also experienced the problem with his car so we both decided to go for the cheapest option first. A new set of plugs and hour under the bonnet and we never looked back. I would put money on plugs being the problem.

Good luck and go easy on the revs until you sort it out or it could go bang....
