R33 Gtr - Need Help With Flat Spots Under Load Or Trying To Get To High Revs

[Speedkills]

Hi. I have a 97 gtr R33. 57,000 Kim,

All standard except exhaust. Which is stainless steel 3 inch unit.

Then coil overs etc.

I had my car stored for a about 3 months - I was overseas.

Put new battery in it - started first go and idled as normal ( really sweet)

- let the car warm up with normal driving, once oil temp was up - tried to give it some curry and all I got was flat spotting all the way through the range. It got worst the more I tired to clear it out.

Any ideas from anyone - I'm too scared to start her up again. What do I do- without getting shafted by some mechanic who will just b----t to me and try and make a mint.

At worked perfectly fine before storage.

By the way, there was not much fuel in it - I filled it with shell V. Then I used half and put injector cleaner in it.

Improved a little but was still noticeable.

I use motul as the oil also.

Thanks in advance
