Camshaft Defaser

[lawser]

After just having my 2003 HPI exclusive serviced the garage reckoned that my Camshaft Defaser needed replacing, now from what little i understand this controls the fuel injection timing. Fair enough the car certainly is a lot quieter now...no longer sounds like a diesel but ever since the service the car hesitates on accelerating and since this defaser has been replaced it certainly is smoother but still hesitates quite badly at times on accelerating.

They now reckon i may need a new coil.....Does this sound right ?

Also to cap it all off my AC and heating has packed in, the blower seems to have given up the ghost , the electronic controls seem to respond but when i try to increase the fan power the electronic display for the fan goes back to zero.

Help......Not a problem for two years and all of a sudden Wham !

I also get the old antipollution fault appearing on a regular basis...any way of resetting this ?

Any help appreciated,
