try leads and coils first. there is a fuel filter. it's in the line just in front of the petrol tank, almost in line with the left rear wheel

As said leads,might be a dirty MAF wire are you running a standard intake.
Fuel filter if you have done alot of K's. At night or a dark carport have the bonnet up run and rev the car see if you can see spark jumping to the heads.
